[Elecraft] K2/100 birdie at 28.020 MHz

[jeff martin]

I have a loud birdie at 28.020 MHz on my K2/100. The KPA100 is integral to the K2. I thought it might be from the 4.0MHz oscillator on the KPA100, but the birdie does not respond to changes of C27. The birdie stops when the power is reduced to low power mode. The birdie is loud...can be heard when the 2nd antenna is selected with no antenna connected.

This may have been covered before, but I seem to recall that there was no firm resolution? I never reaaly worried about it for the past few years, but with the solar cycle waxing, I might miss some DX!

Thanks all for any insight.
