A question has been raised which I cannot (yet) answer. Though I hope to
be able to answer it soon...
If you installed the CW Tuning Indicator PC board in a fully-appointed
K2 (KPA100,KSB2/KNB2/KDSP2), WHERE did you wind up placing it?
I had one installed some time ago (the original KR5L circuit), and I want to
mention where NOT to put it: absolutely do not put it near the plug for the
counter probe! I had mine attached with double-sided tape on the side panel
(this was before I had the DSP, so it probably wouldn't fit there now).
Harmonics of the square-wave oscillator in the chip were picked up by the
counter circuit, which made the readings jump all over the place when I tried to
do CAL FIL. I went absolutely NUTS before figuring out what the problem was.
So, assuming that you can find a place to put it, check to make sure that it
doesn't cause RFI to anything.
