Baofeng DM-32 --> OpenDM-32

I think all of us participate in this in our own ways.  The vast majority of any praise and credit goes to the developers who volunteer their time and energy to do this.

I looked at the original firmware in Ghidra and went cross-eyed.    I thought, hey maybe I can poke around and find something in either the Alpha firmware or the original firmware to help.  But, memory allocations and commands are just something I do not have enough knowledge on right now to make a difference.

Any bugs/testing I do is not a slight against the developers or a demand for functions/fixes.  I've worked in customer service/troubleshooting positions my entire professional career.  Finding, documenting, and troubleshooting bugs is something I DO have some level of skill in.  So, if that is how I can help, it is how I will help.  Granted, my limited radio experience sometimes results in  me making mistakes as well, but the good intent is there.

I don't think any of us expect perfection or a bug-free experience with the alpha, ore even beta releases.  The alpha alone is a vast improvement upon the stock firmware and especially the stock CPS which made programming impossible.

Keep up the great work here everyone!

Hi everyone,

I would like to report an issue regarding modulation selection in OpenDM32.

When changing the modulation type for a channel, the selection is not properly saved or retained. After saving or changing channels, the modulation field either becomes blank/null or automatically defaults to FM+.

Steps to Reproduce:

Press the green button navigate over the channel details.

Change the Mode and then confirm with SK2+Green button.

Re-check the channel settings (or switch away and back to the channel / reboot the device).

Expected Behavior:

The selected modulation should be saved permanently for that channel.

Actual Behavior:

The modulation parameter fails to persist and resets to an empty value or forces itself to FM+. If you choose DMR you get AM and if you choose AM or FM+ you get NULL after the saving.

Environment:

Device: Baofeng DM-32

OpenDM32 Firmware Version: 20260704201545 SoC HR_C7000

CPS / Configuration method: on radio menu

Let me know if you need any logs, CPS codeplug files, or further test results. Thanks again for your hard work on this project!

Best regards,

I wonder if this is just a display issue or if it actually impacts the modulation type.  This could partially explain the quiet/squelch issues on aviation frequencies if those frequencies are not switching to the AM modulation.
