Check it directly. Run the sampler in line to a dummy load, and then
into your amp.
Thing is, we were getting all that mess on the exciter output. It has
NO idea what's coming in on the RX, and there's no way that whatever
the RX was doing would cause that mess of spurs up and down the
band. It was also power supply variable.
Now the amp COULD be pushing something back twoard the exciter, which
would make it look like a bad exciter.
I can't think what external source could give you problems.
(For the others, Matt is way out in the sticks in northern indiana.
Few emitters of any consequence within a long way)
