[Elecraft] K3 in NAQP SSB

[Bob Evans]

Both K3s played very well during the NAQP SSB this weekend (675 Qs, 120
Mults, 8 hours).  I don't normally play in the SSB tests, but I had to miss
the NAQP CW and just needed a radio fix.  On 20M, the DSP (with 2.8khz
filter) filtering really helped.  I played with the high and low passband
occasionally to keep things clean.  When it got really tough, I moved to the
2.1 khz filter.  On 40, 80 and 160 I was able to dig out the weak ones
pretty well even with rain and thunder static nearby.  I had to shut down
for a while when the rain static got so bad on the 20M beam that I could not
copy anything.  I was not able to find a NR or NB setting to fix that.

 

Unfortunately, I was not able to go full SO2R with my new microHAM MK2R SO2R
box and N1MM DVK because of RF feedback getting into the audio lines.  I had
the same problem with my DXdoubler, so I know it is not the microHAM box,
but something in my setup is causing a hollow echo distortion effect in my
headphones even though it is not too bad on the air according to reports.
When I plug the headset directly into the K3, no problems at all.    I've
got to figure this problem out so I can use all this fancy gear.  ;-)  

 

I wish Elecraft would invent and sell a foolproof anti-RF faraday shield
cage to mount each component in because this problem is driving me nuts in
SO2R mode.
