OpenGD77

Just FYI - BTWR admitted they only have 10W non-GPS now despite their page selling the radio stating it's 5W and has GPS. Buyers beware of this seller!

I ordered the 5W/GPS version of the MD-UV390 Plus from buytwowayradios.com but received the 10W version without GPS. It doesn't appear that they have control over the stock of their radios. I thought I was ordering from a reputable place. Can anyone recommend a better source for the 5W/GPS version o...

FYI - I've been unable to reproduce this bug with the stock firmware. I've also noticed switching my duplex hotspot to simplex resolves this issue with OpenGD77 as well. Is it possible the stock firmware is better at handling rx errors?

Hi Jason, Okay. Don't you have any other equipment to test with (like another hotspot, or a nearby repeater, etc ?). Cheers. --- Daniel Hi Daniel, I don't have another hotspot. As stated in the original post I don't believe I've had this issue listening to local repeaters, but then again, there's n...

Hi, I never had that kind of audio artefact, and I'm used to have a bad internet connection. How is your hotspot frequency alignment ? Have you already tried to check with mmdvmcal ? Cheers. --- Daniel Hi Daniel, I have calibrated the TX and RX offset with mmdvmcal and this still happens. My offset...

FYI - Here's the factory calibration of my radio (captured before touching the firmware):

I've only uploaded the UHF calibration since that's what I'm using for my hotspot.

I was able to get another video where I resolve the receive issue by changing away and then back to the channel: https://drive.google.com/file/d/1KWmo-Qo0kA1xmyGzs4tQaNjmkvUgrvTa You have to show in the video how to make this happen. Otherwise its very hard to replicate the problem. Simply changing...

Also - re: the sound at the end of the video - I think that was my dog whining in the background. The only audio coming from the radio is the noise at the start. Sorry for the confusion. I will try to get a better video of this happening (with the channel change fix) asap.

I'm currently using the 10/2/2021 firmware but have had this issue with all firmwares since I originally got the radio in June (R2021052901). In this case I only caught the tail end of the transmission. This happens to about 1% of received transmissions and seems to be more common, if not completely...
