OpenGD77

But I was reading here: https://www.opengd77.com/posting.php?mode=quote&f=25&p=28782&sid=4fe5358def955727c34116c227d3d8d6 DM-1701 works with DM-1801 and RD-5R cables, basically other Baofeng direct USB cables. It does not work with Baofeng UV-5R etc cables that have a USB to Serial converter chip in...

It could still be some internal problem (soldering/broken) with the connector that makes it possible to program the radio but not able to use the audio pins. I don't hope so ... ... have a look at the Amazon site. They sell two kind of program USB cable: - for "BaoFeng Dm 5r Dm 1701" (like what I h...

UPGRADE: Hi All, I bought a DM-1701 from less a month with an external "Shoulder Speaker Mic". Still before I modified this radio to opengd77 firmware, neither PTT and loudspeaker were working. In this days, I was able to test that not working microphone on my Baofeng-1701, with a Baofeng 888S: it w...

Hi SA0BUX,
I use this cable to program the DM1701


I think it is quite different from the GD-77 cable programmer.

At the moment I haven't check the usb pin

Is it something working with the mike? Speaker? PTT button? What happens if you press PTT on the radio and speak into the mike? As I wrote at the begin, still before I modified this radio to opengd77 firmware, neither PTT and loudspeaker were working. When I plug my "Shoulder Speaker Mic" into the ...

And then, because your "Retevis RS111" has the "k" connector, I should think my DM-1701 has something wrong ...
... even if, as I wrote, I can use the "OpenGD77 CPS" program very well with it.
Many thanks SA0BUX

Can't test with my speaker-mic until next week, I know it works with Anytone 878UV+ and Retevis RT3S, can't remember I tried on the DM-1701/RT84. Many thanks, SA0BUX. I tested the wiring connection from the "K" connector and the internal pins of my "Shoulder Speaker Mic", and all was ok. If your "K...

DM-1701 should work with a "Kenwood" K type speaker microphone. But I haven't verified it on my DM-1701. I'm afraid the "k" connector is that of my bought "Shoulder Speaker Mic", same diagram of pin connections! Even if the Radioddity microphone is compatible with: BaoFeng UV-5X, UV-5RX3, UV-5R EX,...

Hi All, I bought a DM-1701 from less a month with an external "Shoulder Speaker Mic". Still before I modified this radio to opengd77 firmware, neither PTT and loudspeaker were working. On the specification of the "Shoulder Speaker Mic" is written: Compatible Model: Baofeng GT-3 / BF-888S / UV-5R Plu...
