John,
If everything in the low pass filter is correct, you will normally have
greater power out on 40 than on 20. So do check all the capacitors in
the LPF area, be certain K2 is operating when on 40 (c48 and C49 are
switched to make contact with ground on the bottom end). Then after all
Perhaps the one thing that we are all overlooking in the nice sound of the
Collins and Drake radios is that their bandpass was much wider than the
modern day radios and today there is far more QRM on the bands due to
increased numbers of amateurs in the same spectrum. I loved my KWM-2 and
I did some A/B testing with my K2, Drake 2B and R4A. The 2B was in
fabulous condition and had the Q multiplier. The 4A had some issues
which made it work just not quite right.
I found the 2B to be a wonderful sounding rig for CW. It was warm and
rich and the signals had a smoothness that was

Not a power supply problem. Does exactly the same thing when on battery

RFC15 is *NOT* open. There is 5 volts on both sides of it.

Don,
Thanks for the pointer. I started hearing pops a while back, even
before my recent KPA installation, and hadn't started to track them
down. I never seem to change only one thing at a time ... but they
definitely started around the time I installed the DSP!

You must check RFC15 with n ohmmeter to determine if it is open or not.
Even if it is open, there will be 5 volts on both sides of RFC15.

Dick,
It is the same as the 'Elecraft' mic pinout shown in the KSB2 manual.
You can download it from the Elecraft website if you don't have a copy.
The bias resistor can be switched in or out via menu selections.
IIRC, the front and back panel jacks can be independent (one with bias

I am not certain what speakers you folks are using for these comparison
tests, but if using the internal speakers, that alone can make a big
difference.
I use my K2 with an external speaker (a 6 inch woofer - amplified of
course) - and I can say that if I feed it to the inputs of my shack
Note that the rear panel microphone connector is a 3.5mm mono phone jack
whereas the front panel connector is the standard 8-pin microphone jack.
Only one connector can be enabled at a time and bias can be selected, or
not, to that active connector. Any microphone plugged into the unselected
jack

I personally think that going the SDR route is overkill - and requires a ton
of code.
I suggested SDR because it's the only way to get
narrow bandwidths, frequency resolution and sensitivity.
The Pro3 sensitivity is limited because it has a minimum
bandwidth of 500 Hz. Even
