I have discovered an odd CTCSS behavior after upgrading firmware to 3.2.20 on H series radios.
Upgraded a HP782 & HM782 from 3.1.01 to 3.2.20. After upgrade, every analog channel transmits the CTCSS tone at exactly 2× the frequency I program.
Testing & Troubleshooting:
Programmed 103.5 Hz → T-SQL scan shows 206.5 Hz
Programmed 100.0 Hz → T-SQL scan shows 199.5 Hz
Programmed 79.7 Hz → T-SQL scan shows 159.8 Hz
Carrier and voice audio are perfect monitoring input from another radio. The repeater simply never opens because it never sees the correct tone.
Tried to downgrade to 3.1.01 but I get “The firmware version [A3.2.20.008] is beyond the upgrade software!”
Any thoughts?

- Brand-new analog channel created from scratch
- Emp De-emp = unchecked
- CTCSS Tail Revert = unchecked
- TX Admit = Always Allow
- RX CTCSS = None
- Full write + power cycle after every change
- Full write of default rcdx file, power cycle, configure analog channel
