Doug,
Well, stuff like that happens to all of us at one time or another. When
it happens to me, I just jot down a "Dear Dummy" note to myself and go
on with life. Glad to hear you found it.

Boy, is my face red. For the benefit of those who helped with suggestions
concerning my SSB issue (power output pegging and out of control on PTT), I
must confess that when I began looking at this again (for the first time in
several years), I had completely forgotten that when I removed the SSB

I just finished constructing the KSB2 Adapter and have installed the unit and
am at the alignment stage (P-19 of the manual).
The Course Carrier Balance Adjustment went fine.
When I plug in the microphone and try the fine Carrier Balance Adjustment the
unit begins to transmit at full output

Fabio,
I cannot be specific, but the most probable area causing that trouble is
the area of Q2 and Q3 (those direct the BFO signal either to the
balanced modulator in SSB mode or back to the RF board for CW) or the
balanced modulator U5.
Check carefully to be certain diodes D5, D4 and D3 ar
Hi,
I just finished installing the KSB2 module on my K2 QRP version (full
optional). I go to operate for the first time but when I push the PTT I get
this problem: the current absorbed increases (the voltage decrease) until it
exceeds the value 4 A (set at this value after some test) and the
Hi Gerhard,
Most reports of "FM'ing" I have been aware of have been due to a low
power supply voltage and/or the voltage varying with the load. I have
not heard a K2 with this problem, but it might be worth checking the
power supply.

Hi group!
I have a little problem with SSB it seems. During the contest last weekend
someone told me I had "frequency modulation" on my signal. Not knowing what
this should mean I at least thought I would check the signal when bands are
quieter. I just did. And although the audio sounds ok there i
