I noticed that it occurs on all bands and that the spurious output is always in the same relationship to the operating frequency so I suspect that it is not because of the PA itself going into oscillation as that would certainly be band specific. It seems that if it is a problem common to all bands and frequencies, it could be due to something with one of the local oscillators. I wonder if it is something to do with the firmware or timing issues? I'm sure someone will come up with a solution! 73, Bob N1KW
