Remember that you have to tune the uplink throughout the pass. Start at
435.160 MHz at your AOS and tune in 5 kHz increments as needed up to
435.180 MHz. The AFC is pretty good and will tolerate you being off to some

The other issue is uplink power and polarity. As I just mentioned in my
other reply, polarity really makes a huge difference. When using an Arrow,
I'll transmit and not hear myself and with just a slight twist of the
antenna, I'll be in full quieting.
