K2 Reciever

Brent Sutphin WB4X
I have had K2 #2571 from its birth about three years ago. (approx.)  I have
always enjoyed the rig.  It has a fantastic RX as I'm sure anyone who has a
K2 will attest.  Anyway I decided I wanted a  QRO rig and bought an
IC-706MKIIG about a month ago.  Installed the FL-100 CW filter and was ready
for the DX.  I took my K2 out of service to give the new 706 a try.  I
didn't like the RX from the start. The audio with the CW filter and or the
DSP is just annoying. It was very noisy, like S9 noise level almost
continually.  The only way I could manage the noise was by turning on the
attenuator.   Then the radio was even more deaf than before.  Fellows I gave
the radio a real good try.  I suffered with it for over a month.  Tonight
while listening on low end of 40 meters, with the usual S8-9 noise and
hearing only a few strong signals, I thought why am I doing this to myself.
I took the 706 out and put the K2 in the same spot.  NO NOISE...just good
clean signals.  It's really unbelievable how quiet the K2 RX really is.  One
lesson learned, if you have a good thing stick with it.  The other
thing......the 706 has to go.  I just wanted to share this with someone.

Yeah, I went the other way, from the 706MKIIG -> K2 and I thought the K2
was broken until I checked it with a signal generator. :)

Why not go with KPA100? I recently did and I have been one happy Elecrafter
since. QRO really helps with DX on low bands. I don't find any big difficulties
using amplifier with K2/100. Output power is changing a bit when ALC works.
Tuning the amp is sometimes hard because of this. I was more worried about
it beforehand.
