You've discovered one of the reasons full duplex is best on the FM sats...you have no idea if you are getting through, because you can't hear while transmitting.
Got another radio so you can work full duplex?

I’ve just started playing with talking on satellites. I’m able to hear all the satellites (AO-85, AO-91, AO-92 and SO-50) that I have programmed on my Kenwood TH-D74, which I use with my Elk dual band periodic log antenna. However no one can hear me or responds to me. I’ve only been successful with my uplink (being heard) on AO-91 on several passes. I triple checked my frequencies on my radio and the 67 Hz tone and they are set as follows: Sat. Xmit Tone SO-50 145.850 67.0 Hz AO-85 435.170 67.0 Hz AO-91 435.250 67.0 HZ AO-92 435.350 67.0 Hz These are the frequencies used when the bird is at its peak. I adjust for doppler on 440 by starting out 10 khz less, e.g AO-85 435.160, 435.165, 435.170, 435.175, 435.180.
Any ideas if something has changed from what is published or am I missing something? Like I said, i’ve been able to communicate on AO-91.
