Antenna Analyzer Update / Syracuse Competition Result

I got a response from MFJ regarding the MFJ-207 and its "dead spot" on 20M and was basically told I could send it in for repair and that the repair shouldn't be more than about $35.  I'm okay with that.  I have only used the analyzer a handful of times in the past few years since I purchased it new but this is the first time I have tried using it on 20M.  It's too bad I didn't realize this when I first bought the unit as I could have sent it back under warranty.  C'est la vie.  $35 isn't too bad and I know they will find the fault quickly and hopefully get the unit back to me before too long.  Apparently the turn-around time at the moment is 4 weeks so it will probably be more than that.  All that being said, the antenna I was trying to measure when I detected the fault is reading about 1.5:1 on the SWR so I should be fine without it.

The Central New York Highland Games and Scottish Festival was a great time as usual.  The shopping was good, the weather was great, the crowd was appreciative and we had a good play.  There were 6 grade 5 bands competing and we tied for first place.  When this happens the "Ensemble" score is compared and because the Finger Lakes Pipe Band scored higher in Ensemble they got the first place and we took second.  Good for them as ensemble is where it's it...at least that's what I've been told.  I'm okay with second place.  It is a vast improvement over our crummy play in Maxville at the Glengarry Highland Games.  I feel a lot better knowing we can play well when we are focused.

Antenna Analyser Frustration

I'm in the process of installing a sloper antenna for 20M.  Summer is clearly on the way out and I want to get this done sooner rather than later as we all know how easy it is to find ourselves doing antenna work in November.  I want to cut this sloper so its resonant on 14.06 for QRP use with my RockMite.  I have the MFJ-207 Antenna Analyser and, if you are unfamiliar with it, it has 5 range settings from A to E.  I use the analyser with a frequency counter so I know exactly what the frequency is when I am reading resonance.  The top end of range D, which is supposed to be 14, seems to end at around 13.5 MHz and the bottom end of range E, which is also supposed to be 14, comes in at around 14.5 MHz.  I am not able to tune the antenna where I want to.  I'm pretty sure this is not by design as the 20M band is pretty popular.  I don't know if this is just a bad unit I purchased but I am definitely not pleased.  I have contacted them via their web form and hopefully I will hear back before too long.  I haven't searched the internet to see if this is a common problem with these units.  I guess that's my next step.
