Peter,
As you say the K2's CW performance can't be praised too highly, however in my
opinion the SSB side is unfinished business.
You might like to look at my web site for some idea of what is wrong, and how
to
improve it.

I have a Sure 527C mic connected to my K2 and I get very good SSB
reports. People praise it and find it hard to believe I'm not running a

The Icom HM-36 works extremely good as a mic also. My K2 did not respond
very will with a dynamic mic.

Hi Peter,
I am wondering if these remarks about The K2 SSB are old. The following is
how I remember the discussions on this subject and I think some of the text

If your filters are adjusted correctly (best done using Spectrogram, as
others have mentioned), it may be that you're not tuning the CW signal to the
center of the filter's band pass (usually set to 600Hz). I recently added a CW
tuning indicator to my K2, and now, once the

Two things conspired to cause trouble with early K2 SSB. Steve touched on
one of them about variations in crystals.
The original K2 SSB filter was purposely designed to be as narrow as
possible to give the signal more punch, especially for weak-signal/QRP
operation. The narrower the bandwidth of

You might encounter a hiss at low audio levels though.

One of you just needs to turn him in to eBay and let them shut him down.
They may not be able to prove that he's not really selling a K2, but he's

Joel,
Certainly you can check the headphone jack with a continuity test. You
should find continuity between the 'hot' side of P5 (pin 1 - closest to the
side panel) and one end of R35 and R36 (the wrong end may show you about 82
ohms). If you find no continuity, then try resoldering the pins of
Pat,
If this condition is confined to 40 meters, check out the KPA100 specific
information regarding the position of RFC10 (the one soldered to the antenna
jack) on Tom Hammond's website www.n0ss.net .
If it happens on all bands, then you have another problem, so ask again and
provide more
