Attached is an image of the signal and 120Hz spaced spurs I'm seeing 
here. Looks the same via e-probe or loop, but the loop snr is a couple 
dB better. The fact the spur spacing is 120 Hz rather than 60 Hz should 
be a clue as to the cause. Transformer coupling between the computer and 
transmitter sounds like a prudent thing to do.
