One thing that has always concerned me about "ham signal reports" in
general. I've heard signals that were 20 dB over S-9 that were great
sounding signals. And I've heard signals that were 20 dB over S-9 that
were lousy or terrible sounding signals. Likewise, for those that are
only 6 dB above my noise floor, those can be great signals or
lousy/terrible sounding signals. Frankly, signal strength means little
to me. The "copy-ability" of a signal is how I determine signal
quality. A CW signal with a clean tone, no clicks, no chirps, no
warbles is a great signal. On the other hand, one with any of those
artifacts will be a lousy signal.
Your K2 should allow you to give and receive outstanding quality signal
reports both on transmit and receive. Be it from 10 watts or 1500
watts, there should be NO Difference in signal quality, only signal
strength.

Hello all,
My new ( to me ) K2 arrived yesterday, far in advance of when Ebay
said it would. Color me happy. I just ordered the SSB adapter.
My first impressions: The UI is a little cryptic - a general weakness
of things with small displays and few knobs/switches/buttons, but really
not too bad. I've already got most of the buttons memorized.
Receive is nice & quiet. When I disconnect the antenna, there is very
little internal hiss. The AF gain control was scratchy at first, but
quieted right down with a little use.
Had my first QSO with it - with Don Huff, W6JL. Don gave me a good
report. Even though I was only
running 10 watts.
I notice that the band noise changes tone between "CW" and "CW R".
Could that be symptomatic of a misadjusted BFO? Also WWV is a little
off - switching from CW & CW-R changes the beat note. Looking forward
to getting into this; Ebay just yielded up a GPSDO ( GPS-disciplined
oscillator ) which is supposed to emit 10Mhz accurate to a tiny fraction
of a Hertz.
I'll want to start inspecting the radio to see what needs updating.
