OpenGD77

Thanks Speaker clicks when playing beeps etc are also in the official firmware, so this appears to be a fault in the electronics design of this radio. I will investigate whether there is anything I can do in the firmware to reduce them, perhaps using the same method of "click suppression" which I u...

The only bugs I currently know about are 1. Problem with terrible audio quality on a Non-GPS radio. This problem may not be related to whether the radio is Non-GPS. Please let me know if you installed on a Non-GPS version 2. Speaker clicks 3. Loose battery connection caused radio to hang 4. Orange ...

Changed to OpenGD77 and so far no issues.

I'll test hotspot mode later today. Register dump sent via email.

Hotspot works flawlessly. Also with the latest firmware you emailed me.

Actually get a longer support tube from a hardware store and also buy some plastic cable ties, you can then use the cable ties to hold the support tube to the corner of the balcony railing. I'm cursed with neighbours and an HOA that are particularly sensitive to "the aesthetics and uniform appearan...

I have a lot of local QRM on 2m but 70cm is better

In your case, why not use 2m? The range will be better than on 70cm

No space for a half decent 2m antenna. Got myself a homebrew 70cm GP from 10€ of parts, though:

OK, it seems the problem is solved. I changed the hotspot frequency just before the problems started appearing, namely to 430.400 MHz as one of the recomended frequencies for hotspots in Spain as per this page: https://ea1uro.com/radio/dmrsimplex/ Although I checked, with both analog and digital rad...

I have a TYT MD2017 which I put to no use. The trackball thingy drives me mad, and the CPS is a pain. So, I'm willing and ready to test on it, and won't mind the (slim, I know you do quality stuff here) chance of total brick of my radio. I'll also try and use it in OpenGD77 Hotspot mode, as my RT-84...

OK, thanks for all the great help so far... Here is a video I've made, where you can get an accurate idea of how it sounds: 9hhBGwl7R2E For good measure, I am attaching my MMDVM config. Maybe I have overseen something there: [General] Callsign=EA7KLK Id=2140410 Timeout=240 Duplex=0 RFModeHang=300 Ne...

Also, here are the logs from MMDVM: On the OpenGD77 / Radio hotspot: M: 2024-01-21 20:51:21.687 DMR Slot 2, received network voice header from 9990 to EA7KLK M: 2024-01-21 20:51:24.526 DMR Slot 2, received network end of voice transmission from 9990 to EA7KLK, 3.0 seconds, 0% packet loss, BER: 1.2% ...
