With no antenna attached on 20M I get no reading on the S-meter. With the

I would wager that your K2 SN is less than 3000 and that your firmware

If both those conditions are true, you will have to add the wiring to

Chuck,
While both sidetone sources should be supported in 2.04P, go ahead and
make the change anyway. Yes, make the cut on the trace ging between
U6-25 and Q5. You will add 2 wires. The one from U8-4 to Q5 (make
certain you do not put it on the R-PAK) is the one important for the
sidetone.
Done,
The sidetone is up and running. Now to recalibrate the VFO and check a few
other things and I will start building the KDSP2.
I have a QRP top with KAT2, KIO2 and KBT2 standing by. #972 will be a fully
