Subject: [amsat-bb] Squelch setting on TH-D72a for FM birds - newbie
Pretty excited I heard my first satellite tonight, but not without
beginner's mistakes. I was not trying to hit the satellite with TX tonight,
just listening to learn the proper exchange.
I think I did my homework and have programmed SO-50 frequencies in my
TH-D72a correctly. I put the radio TX in the VFO "B" position, and all of
the RX in the "A" and turned on full duplex. I left the squelch one up from
open. I hooked my arrow antenna up, and held the antenna right at the
satellite. Nothing. Then I switched to VFO A (RX) and held the monitor
(squelch open) and heard some folks. While still in VFO A, I switched
memory locations while holding the monitor on, to make sure I was on
frequency (these RX memories account for doppler). When I heard a QSO, I
let go of the monitor and the signal did not break squelch.
So my question: Must I leave squelch all the way wide open when working FM
If so, I guess that I need to buy some headphones so I do not introduce
feedback into the TX side while in full duplex.
Could some of you seasoned satellite folks help a new guy out?
