Another source of RF into the Jupiter (maybe the Orion too) is via the TX
EN amp control line. I had a devil of a time solving RFI screwing up the
Jupiter when connected to a Herc II. Ten-Tec Service told me the problem
was that the TX EN line is not RF bypassed. I added a big RF choke on the
line at the connector in the Herc II and it pretty much solved the problem.
I no longer have the Herc II and with my new legal limit amp I have the same
issue when using above 1KW again.... but just haven't had time to sort it
out yet.
