Scott,
The frequency at TP1 (did you mistype? the PLL reference frequency is
read at TP1) does not seem to be a problem. 12090 +/- 30 kHz can be
anywhere between 12060 and 12120 kHz, so your value of 12099.73
certainly fits within that range - it is correct.
As for your receive problem, if you found a nice peak during the
transmit alignment of the bandpass filters (at a 1 to 2 watt level),
then your bandpass filters are likely OK. If you did not observe a nice
peak on any band, then review your soldering in the bandpass filter area.
Check the VFO frequencies (at TP3) when tuned to the bottom end of each
band - they should agree with the chart that is printed on the lower
left of the Schematic Key sheet in the back of your manual.
If you have good VFO frequencies, and the bandpass filter is aligned
properly, you should have receive on all bands. Some bands just have
few signals these days of low sunspot activity, so use a signal
generator or another transceiver operating into a dummy load rather than
relying on an antenna.

Hi
I'm starting the receiver alignment on my k2. It is not receiving on all
bands. 40 and 20 meters is about it.
To begin with, on the alignment and test part 2 I am supposed to get a
frequency reading on TP 3 of
12090 khz +/- 30 khz. I am actually getting a reading of 12099.73. Any idea
what would cause this
and how to get it down to 12090?
Also my frequency counter and amp meter works, but the voltage meter
doesn't.
looking at the schematic I can't figure out which components are involved
with the voltmeter.
I went ahead and aligned the transmitter if this would make any difference
and it has full output.
Any help appreciated
