[Elecraft] K2 SSB Question

[Mike Markowski]

Mike,

I don't have an answer for you, but wanted to say I *think* I am
experiencing the same thing.  I have an old Bird model 43 watt meter
hooked up - not at all the thing to be testing phone output with - and
see one unexpected thing.  SSB sounds fine on my test rcvr on 40m and
80m, 100 W into dummy load, where I see peaks of maybe 20 to 25 W when
speaking into the mic.  But on other bands I see about 2 W!  However,
whistling into the mic gives me about 80 W or so on all bands, and a
quick tune at 100 W gives about 100 W.  At least the amp is ok, so maybe
I'm seeing the greater emphasis on lower frequencies in LSB popping the
meter up a bit more than USB?  That's quite a difference though.  I hope
to get a scope hooked up to better test it.  I just finished my 100 W
amp over the weekend and am trying to make sure all is well.  I did have
a short 20m psk31 qso and was putting out 30 W, same as the power
setting.  But I still wonder at that 20W/2W difference...  The bands
were awful this weekend and prevented better testing.  In any case, I'll
be interested to see what you learn.  I'm using the MD2 mic, by the way.
