My previous postings attributing my Orion's raspy received CW note and
other symptoms to software origins were dead wrong. I had previously
agreed with others that the problem arose when the sweep function was
turned on. The problem appears to be a leaky bypass capacitor in my
Titan 425 amp. Disconnecting the coax between the amp and the Orion,
while leaving the PTT line connected, solved the problem. Substituting
a second 425 RF deck also eliminated the problem. Most likely, a 3CX800
filament bypass is leaking. Apparently, the AC was feeding back into
the Orion through the input coax.
Sorry for the misdirection, but I hope that this information may save
others some diagnosis time in the future.
73, Joe
