This control is far from intuitive. :-) Go to CONFIG menu item CW WGHT and
tap the 1 key. Display should momentarily say CW +SSB (allows CW in SSB
mode) or CW -SSB (disallows CW in SSB mode).

I'm at the end of my yearly K2 alignment and have come to the crystal
filters part.
Currently I have CW filters of 1.5K, 750, 400, and 250 with a side tone
of 600Hz.
On SSB I have OP1, 2.1, 1.8 and 1.6. I'd love some spectrogram screen

If I built a single band QRP CW rig, what would be the best overall band to
select?

I would definitely opt for 40 meters. I've always felt that
if I only had one band to operate on, it would be that one.
40 meters is as close to a 24 hour band as you will find in
the HF spectrum. It also gives you a good variety of
coverage, with DX being very possible much of the time.
You can take it out of the band rotation so that you don't see it when you
press the Band button.
See CONFIG:BND MAP. This may not be all you're looking for, but it might
help.

Hi gang,
The weekly Elecraft SSB net will meet tomorrow (Sunday, 3/1/09) at 1800Z.
We will start at 14.316 MHz, and QSY if needed. The net control is in
western Oregon, but we will need a good east coast or midwest station to
relay a few west coast signals that may be too close to net control.
I pick up stations on my K2 without an antenna hooked up.
I also get way more then enough volume.
I never need or use the preamp below 20 meters.
Did you check the antenna with a different receiver?

Yes, I suppose you're right. I have however tried rerouting all of the

That unfortunately didn't make any difference.

The noise blanker on my K2 is _very_ effective at eliminating the
power-line noise in the area. Many time with it off the noise level is
around S9 or higher and unless signals are very loud I just can't hear
