OK, that makes sense.

Are you saying that the Invalid Channel error is supposed to be there in the "correct" version, or is that an additional issue that needs to be cleared?

« : 06 Августа 2026, 16:14:06 »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+.
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.

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!

« : 21 Июля 2026, 14:23:46 »If I had the latest OPENGD77 CPS Source, which I believe is in .net based I can help troubleshoot this array issue. I have been a .net developer for over 20 years. I see this GitHub but it is over 6 years old. Is there 2026 source available? https://github.com/VR2VYE/OpenGD77CPS. I suppose I could take a shot with ILSpy or JetBrains or a similiar tool if need be. Thanks
You can reach out to the dev directly by email, his name is Roger VK3KYY/VK2KYF. He is pretty responsive and has been working on this firmware port as well.
Part of the issue is right now OpenDM-32 does NOT fully remove the old firmware but incorporates it in the background in order to retain the calibration data in the stock firmware. Eventually, the goal is to ONLY be running the OpenDM-32 firmware without the necessity for the original BaoFeng in any capacity.

I have a very interesting issue that is inconsistent.
I use a KVM switch to use the same monitors and keyboards for both my work and home computers.
About 1 in 7 times, when I press the PTT button on the DM-32 it interferes with the KVM switch and both of my computer monitors go blank.
Now, this is clearly an RF interference issue that is combination of the radio hardware/firmware and the KVM switch not being well-shielded.
I don't know if this is something that can be fixed in the firmware or if it is just a weird quirk of using the radio near other electronics.

Even when I was on the stock firmware, I had to buy a BTECH PC03 cable to work with the DM-32. It seems to be very particular about which wire it uses. My other FTDI didn't work with it.

Right now the firmware doesn't use the whole radio memory so it cannot store all of the DMR contacts. Hopefully, this will be resolved in future releases, but it is currently necessary for retaining calibration and other data.

Testing out the latest version (Amazing work by all the devs)
Aviation frequencies are audible and zones can scan
The signal bar/LED issue has improved
The screen refresh seems to be improved.
I was not able to successfully test the DMR functions. I attempted to test on Parrot off a local repeater and that didn't work. But I cannot confirm if that is just local conditions/my incompetency so, I am not sure if it is a bug or user error.
One weird issue I'm seeing on analog repeaters is that I continue to hear static/buzzing after a received transmission stops. It's like the squelch doesn't turn back on after the transmission. Changing from the channel and back fixes it. But, I will keep testing to confirm this happens on multiple repeaters. Might just be this specific one.
The only other odd thing I noticed is that the FM label in the upper left corner of the radio flashes after locking on a channel in scan mode. I do not know if this is by design or not. It also displays FM for Aviation channels, which I believe are AM, but again, this could be correct functionality.
Note - None of the above two items are complaints or slights against the firmware or developers. I am truly grateful for all the work they are doing and my radio would not be programmable without this firmware. THANK YOU SO MUCH!

« : 11 Июля 2026, 16:59:23 »I am using Ghidra for reverse engineering the Baofeng DM-32 firmware.
I didn't even know about this software. Definitely going to take a look. Not that I have much software dev experience, but if I can find anything that might help, who knows...
What Language did you select when opening the firmware file in Ghidra?

« : 09 Июля 2026, 18:44:28 »Aviation band 118 - 133mhz always squelched, Can’t in mute it.. also cannot scan any aviation band frequencies in his own Zone they will not scan
I just programmed the local aviation channels in and tested this. I can confirm that channels are VERY weak/low volume. I can hear radio traffic but very minimally. I also confirmed that you cannot scan through zones with aviation channels.
Will add to the list post.
