[Elecraft] K3 K144XV spurious signal on 144,414.1

[Sverre Holm (LA3ZA)]

I would appreciate it if other owners of the K3-K144XV would check for this
signal.

It appears as if it is a regular input signal, i. e. it tunes normally. But
it is still there even if the 2m antenna is disconnected or the input is
shorted, so it seems to be internally generated.

I have tried all the tricks I know such as moving of internal cables in the
K3. I also updated the K144XV firmware and that got rid of the spur at the
36th harmonic of the 4 MHZ K144XV processor crystal at 144,005.

But the 144,414.1 spur remains, close to the SK4MPI beacon at 144,412 which
is one of the main indicators of propagation here.
