I just have to say that it is a known problem that if the pegasus or jupiter
is too close to the power supply, a 60 hertz component gets modulated on
the CW carrier producing a raspy CW note. You must keep the power
supply at least 2 feet from the transceiver. The problem is not RF getting
into the transceiver, it is caused by the magnetic lines of force from the
power
supply transformer modulating the oscillators in the transceiver.
I have had several hams listen to my pegasus CW note and all say it
sounds great.
I wonder if the ARRL test had the power supply near the pegasus.
