I seem to recall some users reporting problems with Astron PS's and tentec
gear (though for the life of me, I can't recall the details). I'm having a
problem in that using a 50A Astron (new filter cap) results in a raspy CW
sidetone note... sounds like 60hz but I cant be sure. It happens only when
on higher powers (>60watts) on all antennas (including dummy load) on all
coax, etc etc.
When I switch to a different supply (in this case, another Astron as bench
supply) all is well. The Omni VI that sits next to the Paragon on the
operating table has no issues. Swapping all cables with the perfectly
working Omni results in no change...Omni stays good, Para bad.
The Para has just made a round trip to Tentec and has a clean bill of health.
The Para and omni is being fed through identical TT magnetic breakers.
Ideas? I'm stumped. I've got other supplies to use, but there should be no
reason for this!
