[Elecraft] KX1 Power Measurements by band

[DYARNES@aol.com]

Add me to the list of those experiencing low power output.  I was getting 
under 2 watts on 40, and just over 2 watts on 30 and 20.  Gary suggested I 
increase R30 to 27 ohms and decrease R11 to between 3.3 ohms and 5.6 ohms (after 
first suggesting I check the toroids, etc.).  I made the above changes and my 
power out went to about 2.5 on 40, and just over 3 watts on 30 and 20.  I had 
been behind in monitoring the reflector, and now I see the other comments about 
low power.  I had gathered from my exchanges with Gary that I wasn't the only 
one with this problem.  So, I guess I will dig back in and up the value for R30 
a bit more.  Thanks to the NorCal resistor kit, I have a nice supply.  Then, 
hopefully, squeezing the turns on L2 will be necessary (it wasn't before 
obviously).  My guess is, though, that I still won't get to the power levels that 
Ron and Phil are reporting.  We'll see.

I am also noticing the lack of audio output that others mentioned, although 
on 40 it seems pretty good.  It's just on 30 and 20 that it seems a little 
"light".  But the RX doesn't seem to miss much sensitivity wise.  Pretty darn good 
RX design I'd say.  Everything else seems to be working like a charm!
