Moving shacks

 I don't really have a 'shack' of sorts as most hams do.  I operate from my yard close to where my antennas are.  During the inclement months I would go into my small barn and operate from a small table and chair.  I have a small space heater to take the edge off when it's -30C and that has served me well.  The problem with my barn is that I share it with raccoons and squirrels.  It is an unwinnable battle with the current state of the barn and access points the critters have to its interior.  I'm not terribly upset that they are there.  They don't cause me any other grief...they do not get into my garbage or anything like that.

I also had an old decrepit large shed/building which raccoons lived under and I could store some things in but the doors wouldn't shut properly and the roof was rotting.  It needed to come down.  I tackled the task which ended up being much more work than I had anticipated.  It took two 20 yard dumpsters and two 40 yard dumpsters to take care of it all.  It took me months to deal with this very well built shed.  Now that it's gone I am having a new, but significantly smaller, pre-made 10' x 14' shed delivered from Pine Grove Sheds in Alexandria, Ontario, just 20 minutes away.  This shed will be located on the opposite side of the yard from the barn and I wondered if I could use this new shed as a new operating position or shack.  It will be protected from the elements and the raccoons and I am excited at the prospect.  I was thinking of putting a vertical antenna up as I had originally thought I would also keep the old operating position in the barn until I went in the other day and saw raccoon poop on my table.  I'm done with the barn.  I will move my antennas to new trees and have a new permanent shack.  This will allow me to leave things there without fear of rodent destruction.  I am getting excited at the prospect of this new locale.  I will post pictures once it arrives in a few weeks.

When I was thinking of putting up a random wire vertical I did a lot of youtubing and reading and I learned a lot about the differences between the EFHW and the random wire antenna.  I learned more about 9:1 ununs and their proper application as compared to the 49:1 auto transformer used in EFHW antennas.  I really enjoy when these concepts that I didn't quite fully understand become more clear to me.  I had been trying to use a 9:1 unun for my 80M antenna at 1/2 wavelength.  I had purchased a EFHW 80M mini tuner that plays the role of tuner and matching transformer but a part was incorrect in the bag and had been waiting for its replacement.  I didn't understand why the unun was giving me an "ok" match but not a great one.  I made some contacts but the SWR on the FT-817 was still fairly high.  Now I understand the difference between the 2 antenna types better and the need for the 49:1 transformer and that the 9:1 just wasn't going to cut it.  Once the proper toroid arrives and I finish the 80M EFHW tuner the 9:1 can be put away until the next time I decide to put up a vertical or random wire antenna....with a proper counterpoise.


Cheers for now,

Summer's gone already

 Summertime is not a big operating time for me these days but as the weather gets cooler I start to think of antennas and what I need to do before the snow flies.  I had put up the doublet in the spring and it ran just touching the weeping willow tree because that was the path between my 2 supports.  The antenna got tangled up with the tree and I was not pleased with using the tuner each time I moved on the band or changed bands.  Some bands worked well and others not so much.  I decided to rethink my options.  I had put up an end fed wire for 40 and that was fine with the little tuner I built but I decided to drop it and put up a tuned dipole instead.  The end fed is a compromise and I wanted to do a fan dipole using the window line.  I made one with 40 on top and 17 underneath.  This antenna doesn't interfere with any trees and I reused my center support from the doublet making this antenna slightly inverted V-ish.  Now I have the 2 fan dipoles (20/30) and (17/40) and my EFHW for 80 which I am still not completely pleased with but I have it and will use it this winter.  It works and I make QSOs and that is what counts.

I plan on taking part in more NAQCC monthly sprints this winter and they use 20/40/80 which I now have covered.  I am not a contester but these are low pressure and I really enjoy having 2x QRP QSOs.  The days are getting cooler and my operating position (a lawn chair and card table in the barn next to the window) is ready for me.  The raccoons will soon be coming home to find winter homes and I hope to seal up their access to the barn but it is a challenge as they can be pretty crafty.  They stay on the second floor and don't bother my stuff but I'd rather not have them but that's what you get when you live rurally...that and the red squirrels.


I have  had a couple of QSOs this past weekend but I am still busy with other jobs and not had a lot of time to operate.  Soon enough, I hope.

Tuner Covers the Bands

I took some time yesterday afternoon on the Good Friday "day off" to try out the QRPGuys Multi Z tuner some more.  I started on 40M, where I didn't have any luck finding a match the other day, and had better luck today.  There's a hi/Lo Z switch and when I switched it to Hi I was able to match 40M quite well.  I even had a QSO with Ron, W3SSF, in Baltimore, MD.  It was turning into a ragchew but had to cut it short because of QRM.  30M tunes alright but I can obtain a better match without the tuner. 20M tuned up nicely and I may have had a brief exchange with 4A60O but he was quick and there were a lot of other callers in the pileup.  I didn't hear my exact call but very similar to mine.  He may have misheard my call because of the QRP.  He did not go in the log.  17, 12, 15 and 10 meters also tuned up will enough but those bands were pretty dead so there were no QSOs to be had.  It was a bit chilly but mostly it was a cool damp very strong wind so I operated from inside the barn.  Even with that my fingers were starting to get a little cold so I packed it in for the afternoon but not before proving to myself that this little tuner will work well for me on this random wire through a LDG 9:1 unun until I can get the doublet in the air.

A Beautiful Day

Saturday was one of the nicest days we have had in quite some time.  The wind was down and the temperatures were in the mid teens.  This was a perfect opportunity to spend some time outdoors.  As the yard dries up there will be a lot to do and being stuck at home will give me no excuse not to get stuff done.  After first doing some raking of twigs from the weeping willow (there are sooooooo many from this sort of tree...especially after a windy winter) I figured it was a perfect opportunity to do some outdoor operating.  I got my lawn chair and collapsible table out and brought out my portable kit.  Everything is still brown but it's better than being white.  I took this panoramic shot.  This summer my plan was to have that old storage shed taken down and removed but with COVID that has fallen down the list of what is important.



The sun was warm and I hooked up to the random wire.  Since 30M is the only band I can work without a tuner that's where I parked myself.  The DX stations I could hear were too weak for them to hear me so I had a couple of QSOs with domestic stations.  The band was fairly active.  I could hear at least one SOTA station and a couple of SKCC stations.  I was unsure of the SOTA exchange.  I was unsure if someone calling CQ SOTA is looking for a SOTA station or they are activating a SOTA station.  With my CW operating confidence (or lack there of) always hanging over my head I avoided the SOTA caller and instead my first call was a 2x QRP with AA9AA in Wisconsin and I always enjoy a 2xQRP...probably one of my favourite contact types.  I also called back to an SKCC station and had a brief QSO where we exchanged SKCC numbers names and Stare/Province.  I was just listening to some of the DitDit podcasts this week and one of them was all about the SKCC.  I've had a SKCC member number for over a decade now but I've never done much with it.  It's nice to be able to have a brief exchange with someone with a shared element.



I'm happy the snow is gone now and the yard is drying up.  I'm going to appreciate the increased radio operating time I'm going to have this spring.  Soon we will be planting the vegetable gardens and getting the flower patches cleaned up.  The perennials are already coming up.

With the warmer weather, as well, is the ability to start practising my bagpipes outdoors.  It's not an activity conducive to indoor practising when it comes to not annoying other people/cats in the house.  Soon, I hope.

*NOTE - I looked up the SOTA details and found that someone calling CQ SOTA is, in fact, activating a summit.  There's a whole community of chasers out there too.

Still a bit chilly...

I went out with full intention of getting this antenna going.  After I put sheets on the clothesline my hands were already chilly.  What I decided to do was start fiddling with my support pole idea.  My plan is to make a pole by connecting 2"x2" pressure treated end to end until I reach the height I need to sufficiently support the center of the doublet.  Because it will be guyed I am not too concerned about strength.  What I will do is place four twelve inch 1"x2" around each joint to provide support.  It won't be pretty but should do the job.  I will guy the pole at the top and again at some midway point.

My biggest dilemma was what to do at the top to hold the antenna in place while still providing for some up and down movement as the antenna flexes with the wind in the trees.  In the barn I found a 3' fiberglass section from a 20' Shakespeare Wonderpole fishing pole that I used to use for portable dipole setups at parks.  The tip had broken off when I dropped it from the second story roof peak one time (on purpose...I thought it would land flat but it didn't).  Anyway, I plan to drill a 1/2" hole in the top end of the top 2x2 section and glue it in place.  I also drilled a 1/2" hole in the top of the plumbing T so it will slide over top and sit on the top of the pole.  The photos below of my plan explain this better than my words can.  I just did this in a scrap of wood to prove to myself that it should work.






The T is able to slide up and down on the fiberglass shaft by as much as 2'6" and I will put something on the tip of the fiberglass shaft to prevent the T from sliding up and off the top completely in strong winds.  Now I need to investigate what length of pressure treated 2x2 I can get (10', 14'...16') because I'd prefer not to use 8' lengths so I can have as few joints as possible in the mast.

The other thing I did was measure out the antenna wires on the ground at 73' each.  I left them on the ground for now and called it a morning.  If it warms up I will go out and solder the center connections.  I can make and put the antenna up without the support pole.  The pole is just an addition I will install to steady the antenna in the wind I will inevitably get here in farm country.  I am also still trying to figure out how I will get the para cord over the top of the 60' tree.

Doublet length

So I had decided to install the 40m (and higher) doublet to save on weight even though I had the space for the 80M doublet.  My original thinking was that some day it might be neat to compare the EFHW 80M antenna with the 80M doublet since my QRP Guys tuner that I plan to use with the doublet does not support 80M.  Then I read that a doublet will actually provide better performance on a given band if the antenna were resonant on odd harmonics for that band so I thought that since the doublet length is not critical I could play with the length to give a boost to a favourite band.  I knew there are websites out there that will calculate this for you so I went searching.

I looked at a couple and then found this page on Spookmate.com.  I was able to put in the frequency for 80M in the calculator and see what my options were.


As you can see where the harmonics are listed that 10.5 is the 3rd harmonic.  This is very close to 10.110 where I like to operate on 30M.  I then adjusted the frequency at the top until the 3rd harmonic was where I wanted it to be.  3.37 MHz does the job and the legs of the doublet would be 72.9' long.  The key with the doublet is that the antenna is not resonant on 80M if I want to use 80M.  It is not (although it may be too close) but I am not using the antenna on 80M so I'm not concerned about that.  Really I'm taking advantage of the 3rd harmonic which I would not have if I were to put up the 40M doublet.



The harmonic frequencies gave me no joy for the 17M band which I also enjoy so I will go with the 73' length.  This is what I plan to experiment with when I put this doublet up, hopefully this weekend, weather permitting.  I'm not sure how much luck nor do I have a way to get tangible results but my random wire is currently working well on 30M only so I can compare the two.

Now you may remember I was going to avoid the 80M doublet because of weight concerns but I have come up with a plan for a guyed wooden support pole.  It'll be a little "interesting" looking but I think it should do the trick.  I'm fine tuning my idea in my head daily and am almost there.

Doublet Dilemmas

When it comes to installing my, yet-to-be-built, Doublet antenna my biggest concern is weight and whether it will need a center support.  If it does need a center support what will I use and how strong will it be?  My original intention was to install an 80M doublet just because I have the space but that antenna will be significantly heavier than one for 40M.  The QRP Guys Multi Z Tuner that I just completed only tunes 10-40 so an 80M doublet is definitely overkill so it only makes sense to only put up what I will need in the immediate future.  As well, I have my random wire that will be modified to be my 80M antenna with the addition of the QRP Guys EFHW mini-tuner kit for 80M.  Once these projects are ready to test I will do so using my FT-817.

Here is the image from the QRP Guys website:



If I still need support for the doublet I have a couple of options I've been contemplating.  I could use a guyed wooden support made from pressure treated 2" x 2" or I could use a guyed PVC water pipe mast with about the same 2" diameter.  I live in a windy location but the center of the doublet will be somewhat shielded from the wind by my small barn but I still worry about it.  The wind on the antenna wire is not my concern as much as the window feedline is.  It is both heavy and easily caught by the wind.  Only putting it up will tell how these factors play out in real life.  The height this antenna will be remains unclear but I am hoping around 40' up.  One end support is the 40 foot TV tower attached to my house and the other end is a tree over which the para cord will be tossed so the actual height of that end support remains to be seen.

The center of the antenna, since I am unable to 3D print at the library is going to be something I have used before for dipoles, although this one is a bit larger.  It is a PVC water line "T".  It's durable and lightweight and I can easily drill or melt holes for the wires to pass through :

During these times...Projects

With everyone pretty much stuck at home in isolation it's a great opportunity to think of antenna projects and other things like that.  I installed a random wire antenna last fall but with my Z11 tuner is not tuning it at all (I'm not sure if it's broken or just a bad setup) I can only operate it on 30M which is fine by me as it's one of my favourite bands.  That being said, i ordered 2 little kits from QRP Guys.  The first kit was the EFHW Mini tuner.  There are 2 versions to choose from and I chose the 80M version.  This little rig will hopefully help me turn that random wire antenna into a dedicated 80M EF antenna.  I will have to lower it down and add about 10 feet of wire to get to the recommended 135' starting point.  The below photo is from their site.


The second kit I purchased was for the Multi Z Tuner 10-40.  My plan with this little gem is to use it with the doublet I plan to install over the coming weeks.  I have the wire and space to install up to an 80M doublet and I figure I might as well go that route even though this tuner will only help down to 40M.  This kit is a bit more involved but shouldn't be too bad since there are no SMT components involved.  Here is the photo from their website:


A few years back I bought a good length of 450 ohm window line for a project that never came to fruition so now I can use it for this.  I have heard a lot about these antennas and the multi-band properties make it attractive.  I've always been one for using tuned dipoles but in my windy location they are a challenge to maintain.

I did have a plan to have the center support insulator 3D printed.  I found a nice one on  Thingiverse but the local library, which has the printer, is closed until further notice so I may just have to fashion one up.

I will post my progress with the Multi Z Tuner as I tackle that kit first.

Spring is Here Today


With the lengthening days, warmer temperatures and the reality of being stuck at home due to work policies surrounding the COVID-19 "situation" has me thinking about radio a lot more often these days.  Last weekend I decided to do some outdoor operating using my random wire antenna.  The temperature was 4C so it was quite bearable and I also had a nicer view than I would have had I sat inside looking at the barn wall.  Basically I sat just outside the barn window and ran a short length of RG-174 out the window to a chair.  The other end was connected to my LDG 9:1 Unun.  I set up and in 30 minutes I had 3 nice contacts on 30M and two of them were 2xQRP which always makes me extra happy.


 I have my rig, battery, key, clock and ear buds in a small Pelican case which I lined with "Cubed Pick Foam" from the local Canadian Tire store.  This allows me to keep everything organized and works a lot better than the computer carrying case I used to use.  The battery is a 7mAh and is heavy and would crush the other things in my bag.  Now it's held snugly in place by the foam. 
I have a small collapsible camping table and it worked great for keeping things off my lap.   I enjoy being outside again and with the COVID crisis looking like it's not going to end any time in the near future it will give me a chance to operate more often that I otherwise would have time for.  I am also taking some of my spare time to brush up on my code rx speed.  I started out using the standard G4FON program I installed years ago but have been found two other resources that are extremely helpful at increasing character and word recognition which will help with head copying and get past the barrier that exists when you try and write everything down during a QSO.  One of these resources is Kurt Zoglmann's Morse Code Ninja site which is full of links to Youtube videos he's created with all sorts of words, prosigns, call signs, etc at various speeds for aural practice for word and character recognition.  He has learned Morse Code to the extreme where he has even had books converter to code and listens to them.  He's pretty hard core on code.


The second site is called Morse Camp and it is quite simply laid out and easy to use for word recognition.  It plays words for you at a predefined speed (default appears to be 30WPM) and keeps repeating them until you think you know what it is and hit the space bar.  This shows the word or letter/number combination and you indicate with a left or right arrow whether you were correct or not and it moves on.  You can select word length but as you progress it increments on its own.

I think this seclusion we are all experiencing can be a challenge for those who suffer from anxiety or depression, let alone the rest of us who are also feeling the stress of the unknown be it job security, financial security, or even toilet paper security, apparently.  They say the key is to make sure to get out of the house for a walk or a hike or some other stress relieving activity.  Radio is that for me and I plan to do it as much as I can fit it in.  I don't need to sit there for hours...30 minutes is plenty and even just 1 QSO makes me happy when operating QRP.

Change of plan

My plan a few days ago was to build a maypole-style antenna supported in the center with inverted vee antennas coming down around it.  I was worried about the wires coming down all over the place and I also realized that there must be another cheaper and more easily implemented solution.  I have done some reading in the ARRL antenna book and also done some youtubing and now have a new plan.  Now my plan is to install a single wire, centre-fed, with balanced window line.  As long as I am at least 1/2 wavelength long from end to end, on the lowest frequency I plan to operate on,  I can feed it to a simple tuner for multi band use.  My tuner of choice will be the QRPguys Multi Z tuner for 10-40M.  I like the way this tuner has an LED that dims as a match is obtained eliminating the need for an SWR meter which is a huge benefit if I take this tuner to the field.  I have watched a great Youtube video on the building and testing of this tuner and I really like what I see.  For $40 US plus shipping I don't think it can be beat.



My existing long wire can be used for an end fed half wave (EFHW) antenna on 80 meters.  My first option is to adjust the length and try and use my 9:1 Unun to make it resonant on 80.  Failing that I can feed this into a QRPguys EFHW mini-tuner for 80M.  I may need to add some length to the existing wire since the recommended length for 80M use is 135'.


If I cannot get it working well enough on 80 with the LDG Unun I will likely order both kits at the same time so I can save on shipping costs.

Less than favourable results...sort of

So I installed my random wire antenna from my barn out to a very tall poplar.  I used #10 wire so that the strong winds at my QTH wouldn't break it and I have about 130' of wire up in the air sloping up towards the top of the tree with the last 50' or so being para cord over a branch and down to the ground where it's tied off.  At the shack end I am using a ceramic egg insulator to a rope tied through a pulley attached just above the barn window to a bucket of bricks so that strong winds won't break the wire.  I then have another wire soldered to the antenna wire which comes into the "shack" to my LDG 9:1 random wire unun.  From there I connect straight to the radio.

I used the Agilent Field Fox to look at the resonance points on the antenna and saw that it wasn't really well resonant on any band but it wasn't too bad on a couple.  I added some radials on the ground of varying lengths and according to the Field Fox this made things worse.  What I really need is a MFJ-16010 L-network tuner to finish things up for me.  As it stands now, when I hook up the FT-817, the only band that presents no SWR issue is the 30M band.  30 has always been one of my favourite bands (along with 17 and 12) so I'm not extremely upset by it.  We are in a dismal part of the propagation cycle and I was still able to have a few QSOs on Sunday (Jan 12th) including a QSO with Ron, K5WLT, at almost 1700 miles in Texas and a 2xQRP with Alan, KR4AE, in Cleveland Georgia which is almost 900 miles away.  It's certainly not as good a distance as I can get with far less power during better propagation periods but I like the fact that I can still make QRP contacts, albeit with 5 watts.

Of course, as with many hams, I'm thinking of other antenna ideas.  The one that interests me at the moment is the Maypole style antenna.  I am a proponent of the fan dipole antenna and this is a variation on that.  The problem I have at my QTH with wind can best be defended against with stronger wires but thicker wire is heavier making supporting the center more challenging.  What the Maypole antenna does is use a non-conductive centre support with the inverted-vee antennas equally spread out in all different directions around the circle (looking from above) acting as guy wires and also not interacting with each other as much as with the standard fan dipole.  This antenna can be fed with coaxial cable but you'll want to keep the run as short as possible to reduce losses.  You could use a 1:1 balun or choke at the feed point to reduce feed line radiation but I don't think it's really that necessary, especially at QRP power levels, based on my use of dipoles in the past and from what I've read on the topic.  The leg pairs will all be of different lengths making the "V" angle different on each band but this shouldn't change the feed impedance too much.  The legs should not touch the ground but can be attached to stakes or pegs with non-conductive guy ropes.  Since I am operating QRP power levels I am not worried about RF burns but at higher power levels you should keep the antenna elements out of reach of people.  The key now is to choose which bands I want to operate on and figure out the best type of centre support to use.  There's PVC piping but the strength is suspect if it gets too tall and there's also wood or fiberglass.  I'm not quite sure yet which is the best choice.  As it stands now, this antenna will take up a fair bit of real estate and cutting grass around it will be a pain but if it works well it will be worth the extra effort.

A Lot of Time has Passed...

 Well, it's been quite some time since I've posted as I have been busy with other things in my world.  I am happy to say that I am getting back in the saddle on both HF and VHF.  For VHF I had a nice Alinco for local repeater work however my local HAM pals are now using (and have been for some time) a closed digital repeater system they have set up on many bands so the only way for me to chat with them is on a newer digital rig.  I haven't had a rig in the car for a number of years but I have decided to take that plunge again.  When ever I am in the market for something I watch for used items on the Kitchener-Waterloo Amateur Radio Club's Online Swap Shop.  I have been looking now and again for a used digital rig and this week I got lucky and found a HAM selling a Yaesu FTM-7250D which was priced nicely and in great condition.  I should be receiving it in the mail today and I will install it this weekend so I can use it during my commute next week.


In the HF department I had always used a fan dipole for multi-band operation.  I live in a very windy area surrounded by farmer's fields and my antennas often got tangled or worse.  As well, my office/shack has been re-purposed and is not the best spot for operating anymore.  My plan now is to set up a new long wire antenna for multi-band use from a small barn I have near the house.  I have always wanted to experiment with one of these compromise antennas and this way I can give 80 meters a go as well.  I will post my experimentation/installation results when I get them.  I have an LDG Electronics 9:1 Un-un on order from Radio World in Toronto and if it arrives today and the weather isn't too wet I may get to this project this weekend as well.  I will use the Keysight N9913A Fieldfox to get a good idea of the VSWR and performance on all my beams of interest and also see how adding additional ground radials changes/improves my situation.



In other news I am still in a Bagpipe Band in my community and I don't see that changing any time soon as it is a lot of fun.



Cheers for now and I'll see you soon!

Silent Too Long

Well I went the whole winter without even turning a radio on and I was worried that I had lost my interest.  A lot has been going on which has had my mind on other things but all it took was listening to a couple of episodes of one of my favourite podcasts the QSO Today Podcast to get my mojo back.  I can always count on Eric (4Z1UG) to kindle my interests...especially on the QRP front.  I also believe some of my issue was the havoc the wind has been playing on my inverted vee antennas (not to mention the grim propagation these days).  The tangling that occurs with the fan dipole style of antenna is disappointing.  I need a better solution and I believe I may have found it.  I read an article in the ARRL Wire Antenna book that I bought from Amazon last fall.  The antenna from the article I read has the radiating elements made from ladder line/window line.  I can have a 2-band dipole that will not get tangled because the wires are evenly spaced/separated by the windows.

What is done is the length of the longest leg (34' for 40M) and the length of the shortest leg (24' for 30M) are added together making a 58' piece of ladder line the requirement for a 40/30 fan dipole.  Then you lay the cable out and measure 34' from one end and cut the top conductor.  Measure 34' from the opposite end and cut the bottom conductor.  What you have now, if you cut along the red line as shown below, is 2 pieces that will act as each leg of the dipole.  The long top wire is one side and the long bottom wire flipped over and end for end is the other side.

Then you need to strip the conductors bare at the double wired end and solder them together and attach them to the coax to create the feed point.  One leg connects to the center conductor and the other side to the braid of the coax.


Once this is completed you will have to raise the antenna and tune it for your desired operating frequency as with any dipole antenna.  I plan to build two of these.  One for 40/20 and one for 30/17 and I will post the results including photos of the tuning and testing process.

Cheers and thanks,

Hawaii - Out of the Blue

I turned the radio on this afternoon for the first time in almost a week.  The bands seemed quite quiet for a mid-afternoon Easter Sunday.  Down at the bottom of 17M band was KH7XS on 18.070MHz.  The Big Island Contest Club is located in Laupahoehoe on the east coast of the Big Island 4783 miles away.


Their antennas did all the work today as they have quite a setup.  I had 5 watts into my inverted vee here in Eastern Ontario and through a little QSB and a few attempts they came back to me.  It was a fast operator for my speed and experience but I got the QSO in.  It was not quite 1000 Miles per watt (957) but I know that Hawaii is not the easiest contact to acquire if one were collecting entities for WAS.  I do not really operate towards any particular awards but was pleased to get HI nonetheless.

The Radio Room Clock

Along with maps I think Hams are particularly intrigued by a nice clock.  Of course we always want a clock to put UTC time on and what better way to do that than with a clock that is both a time keeper and a conversation piece.  For those who are not familiar with the radio room clock or have seen it but were unaware of its significance.  The clock is easily recognisable with its green and red colour wedges at the quarter-hour points of the clock face.


The origin of the radio room clock goes back to the early 20th century.  Following the sinking of the Titanic, it was decided that coastal and marine traffic all use 500 kHz as the communications frequency for Morse code traffic.  The problem with this is that it made it a very busy frequency.  If a ship were to send a distress call on 500 kHz it could be lost in the congestion.  To remedy this problem, the Service Regulation stated that "Coastal stations engaged in the transmission of long radiograms shall suspend the transmission at the end of each period of 15 minutes, and remain silent for a period of three minutes before resuming the transmission."  This would allow distress calls to be heard.  As an aid to radio room operators, clocks were designed with a red wedge at 15 minutes past the hour and 45 minutes past the hour.  You can see this in old photographs but in Black & White, of course.  In later years a second set of wedges was added to the clocks at the top and bottom of the hour but these wedges were green in colour.  These represented silent periods twice per hour on the 2182 kHz for voice distress calls.

In the 1990s, with the decrease of the commercial use of Morse code traffic on 500 kHz, it was being monitored less and less until 1999 when it was discontinued.  Today there are many companies that sell replicas of the Radio Room clock and I got one for myself from Amazon.  It is a fine addition to any shack and will often be a conversation piece.

Podcasts

I know I am late to the game on this but I have just discovered Podcasts.  I was going on a trip and wanted something to listen to on the plane just in case my flight had no TV/movies available.  My iPhone has a podcast player so while I was at home on wifi I went in and started to do some searching for Ham Radio.  I found a few different sources on various topics so I downloaded a bunch to my phone as well as one that I knew was good that was not ham radio related.  The first leg of the trip was a very short (Ottawa to Toronto) 50 minutes so I just listened to a podcast.  I enjoyed it very much and proceeded to listen for the duration of my 7+ hours of travel.  I did the same on the return trip as I was totally hooked.  Not all podcasts are created equal, for sure, and some I listened to, although possibly full of interesting information, were difficult to listen to as the presenters were seemingly unprepared or simply just not very good at presenting.  

There are two main types of Ham Radio podcasts I found.  One type has the presenter speak on a number of topics.  These were OK but lacked the breadth of knowledge and experiences that come with the second type of Amateur radio podcasts I found which is in the format of presenters interviewing guests.  This format, depending on the guest, is far more informative and captivating.  Listening to these podcasts made my travel time pass by quickly and painlessly.  The first podcast I got hooked onto is the QSO Radio Show.  This Podcast is not only a podcast but is also a short wave broadcast.  The program is hosted by Ted Randall (WB8PUM) and co-host David Klimkowski (KG4WXW).  Ted is a broadcaster/engineer by profession so the program is very professional and quite informative.  The guests interviewed ranged from manufacturers of Ham Radio equipment, ARRL Engineers, the CQ magazine Editor and many more.  There are advertisements at various points throughout the podcast from his show sponsors which is to be expected.  The podcasts are usually about 2 hours in length.  



Another enjoyable podcast I found was the QSO Today podcast hosted and prepared by Eric Guth (4Z1UG).  What he does is choose a notable amateur operator as a guest and then proceed to ask them a host of questions, generally the same from show to show.  The carefully chosen questions evoke great discussion and result in 90% of the talk being provided by the guest.  The topics discussed are quite varied and the guests come from far and wide.  The audio quality from the guests is sometimes not the best as Skype is used and the surroundings at the guest's location of the line cannot be controlled.  This is soon forgotten once the discussion begins and I am enveloped by the content.  This is by far my favourite ham radio podcast.



Another type of podcast is the deep technical "work bench" type discussions found in podcasts like Ham Radio 360.  Some of their podcasts are the "work bench" style while others are more guest discussion based.  Both are very informative and some are multiple hours long.  These are great for gaining insight into how various things work such as Oscilloscopes but at an in-depth level.

  
Another, less time involving but equally valuable, type of podcast is the short "Quote of the Day" or QOTD podcasts provided by The Morse Resource and Steve Conklin (AI4QR) that are sent in Morse code at various speeds,  The actual quotations are provided courtesy of The Quotations Page.   The podcasts last a few minutes and are great for working at improving your Morse receive skills. 

I am so glad to have found podcasts albeit years after they have become popular.  I also listen to some non-ham radio related podcasts and there are thousands out there to choose from.  You can subscribe to them as well which means that you always have the latest podcasts ready to download.  Make sure your player settings are such that you only download these shows when you are connected to wifi.  Do yourself a favour.  If you haven't checked out this medium, have a listen with your favourite podcast player or even just from your PC.  You won't be disappointed.

Cheers and thanks,

Make the time

Wow I haven't posted since February!  That's what happens when you decide to move.    Packing and removing antennas and all that sort of thing really puts a dent in your operating time.  We have moved to a larger place about 20 minutes away from our old place.  This is a good thing.  The place is larger and closer to my pipe band practices.  It also means that my shack is on the second floor now instead of the basement.  I'm looking forward to that for sure.  I don't have anything set up in the shack just yet because there are so many other "house" things we have been busy at.  Minor renovations and painting seem to take a lot of my spare time lately...that and pipe band.  I do have a TV tower coming next week so that will be a start allowing me to get my VHF antenna up as well as a place to string my wire fan dipole from.  I hope I will be able to hit the VE3ORF repeater from my place with just 50W.

There's no rush on the tower work, of course, because as with most hams I'll likely leave that tower work to November when I'll need to wear gloves.  There's so much to do in a "new" house.  It's 100+ yrs old so it's not new...just new to me.  You always want to make a place your own and our place is no exception.  We have just under 2 acres and in the very center of the back yard is a monster weeping willow.  I may use it to anchor one end of my wire antenna however I'll likely need to use a pulley and counter weight system because I'll bet it will sway in the wind substantially.

I'm looking forward to getting my first contacts from the new QTH so I really should get going on it. I think the best plan is to take a week off in October and get it all sorted out.  As I've learned over the years, it's not about finding time for this hobby...it's about MAKING time for this hobby.

Thumbs Up for QRP

I was reading recently about some old military radios that only put 5w out but the radios were huge.  It got me thinking about QRP and its operators.  The great thing about this hobby is that even within a sub group such as QRP there are further subdivisions.  There are the backpack/outdoor operators operating Altoids tin radios from a 9v battery and boat anchor enthusiasts whose tubes keep the shack comfortably warm.  One is low power as in not a lot of power consumed and the other is low power out of a rather large army radio using quite a bit of power in the process.  Technology has come a long way from the invention of the tube to the invention of the transistor and then as the years passed there has been the packing of these transistors into chips.  Now we are at the point, with Software-Defined Radio, where micro processors do almost all of the work that hardware used to do.  Add to all this the digital modes that have been designed to use very low power and operate almost in the noise floor.  Whether it's old, newer or newest or somewhere in between, QRPers love a challenge.  We are always looking for the most efficient battery or best gain antenna or the most portable set up all in an effort to compensate for the low power being transmitted.  I think it really fosters the Marconi in all of us as we try this or that to get the best results in an effort to get the most out of the least.

Antenna Project

I often talk about operating in the field again.  I used to do it quite a bit.  I loved setting up in a park at a picnic table whether it be winter or summer.  It was a great way to spend an evening or afternoon.  I also used to go camping and set up an antenna for the weekend operating at will.  It was lots of fun.  Before we know it priorities change, hobbies change and we sometimes find that we can no longer "find" the time to do the fun things we used to do.  One needs to "make" time for these things and stop making excuses.  I spend a lot of time in the summer going to Highland Games or pipe band practice and I really enjoy it but as a result playing radio has taken a back seat.  This summer I vow to operate outdoors even if it's in my own back yard.  It's not like it takes a lot of time out of the day.  An hour on Sunday mornings or in the early evening shouldn't be hard to set aside.

I think what I will do as an operating position is to try the vertical buddipole style of antenna suspended from a rope in a tree.  Two Hamstick-style antennas and the appropriate bracket is all that's required and I can leave it up if I operate on the back patio.  Here is a good page showing the set up and some results achieved by W3ATT.  I will start with one band, say 20M, and perhaps 30M 17 or 12 as I like those very much...maybe 40M.  I can't decide but either way I look forward to trying it as soon as the snow starts to melt.

Propagation...ugh!

With the approaching cooler weather so comes the antenna work that was procrastinated all summer long.  I installed a sloper for 20M and have been listening to it each evening for a few minutes calling CQ occasionally.  I have installed it semi-permanently and want to finish the job but the conditions have been so poor I am unsure how it will perform.  I also have some other work on a FAN dipole that I need to take care of soon.  These poor conditions are not favourable to the QRPer for sure.  I hope it isn't like this all winter or it's going to be a long one.  Here's an image for the dart board:
