DOPPLER CORRECTION GUIDE
AOS — Approaching

70cm downlink appears HIGH → tune RX up from nominal.
AO-91 uplink (70cm): transmit below nominal.

TCA — Overhead

Doppler is zero. Use nominal frequency.
No correction needed on either band.

LOS — Receding

70cm downlink appears LOW → tune RX down from nominal.
AO-91 uplink (70cm): transmit above nominal.

TH-D72 Full Duplex Setup: Press DUAL (0) → Band A = downlink freq → Band B = uplink + CTCSS → select Band B as TX → [F]+[DUP] to enable duplex (“DUP” on display) → insert earphone into 2.5mm SP jack (REQUIRED) → set audio balance to Band A.
