List:
Looking to help a good friend and DXpedition contester with
an apparent audio problem.
Using writelog and has *.wav files all recorded with a
laptop. Hooked up headphones out to radio with a y cable at
the mike in (Heil head set) adaptor. The radio is a ICOM 756
Pro II. Hum and feed back is noticed in the monitor.
My question is if I build a cable with an RS isolation
xformer in line do I need to not connect the ground side of
the transformer on the radio side? I see this in some
schematics of this type of hook-up. I thought the xformer
isolates the sound card from the radio and this doesn't
matter.
Someone who is using a laptop with writelog, Pro II and wave
files for keying please respond. On or off list doesn't
matter.
