Thank you for the advice so far. Unfortunately, the problem is deeper
than just filter adjustment. I tried tweaking the filters back and
forth quite a bit on 30M without getting any stir out of the external
wattmeter.
I am now on page 6 of the K1 manual. Under "Transmitter Signal
Tracing", the following voltages were seen with the scope. Note that
most of them seem to be DC, not waveforms.
PRE 0V
ATTN 0.1V
OSC 5V
MIX 0.5V
BUF 8V
TR1 7V
BPF ~3 or 4V
TR2 2V
TR3 0.7V
DRV 0.1V
PA < 0.1V
ANT < 0.1V
RFD 0.15V
My scope may not be well-calibrated, so don't read excessive precision
into these numbers. But they are WAY off the manual guidelines.
