My K2 is full operative since 10-febr, today I decide to see in the
spectrum analizer how clean is the output and check the power output in
a calibrated power meter.
The K2 has the ATU inside, so aditional filter in in line with the output.
Power is 13.2W from 3.5 to 18, down to 12W at 21Mhz,
Hi Dom, thanks by your fast answer, as usual. For now i rebuild the T2
transformer, the new one is at 2 mm from pcb and is exactly as the
manual show. No diference at power was noted at any band, just as
before. Recheck at band pass filters parts was also done, and all is
rigth there. So i
I finished the K2 the days before ARRL contest, time to build a 10m
higt antena, no traps and no coil in the base, all the job for the ATU
inside K2. The keyer was the built in in the K2, no CT, i want to check
all the K2, not only the radio part, so Fast play ant all the other
features was
I am happy, my K2 is ready to his first qso, just waiting by a decent
antenna, now receive signals in DX 80m band.
Just one BFO setting question. This is a only cw K2, no ssb module
pluged, all the setting are fine but in USB the bfo at Call Fill can
not get a frequency as in other modes, in

Hello all, i am in the adjust phase of build my K2. My main problem not
solved yet is that 8V tx voltage line is with 5.1 v permanet.
Microprocesor tx order is down and rx is up, so here all is rigth,
colector of Q1 is with 5.1. Also RX voltage seem to be down, not 8V but
6.5. Receiver work, i

Jesus,
You will have to resolve that problem before proceeding.
The most likely cause is something wrong with Q1, Q2, Q3 or Q4 on the
control board.
First check the operation of the TX and RX signals. During Receive, RX
should be near 5 volts at the gate of Q4 and TX should
