Switched the duplex hotspot to simplex mode. works perfectly. No more missed transmissions in or out now. If anyone has any idea what i need to change on the duplex hotspot to get it to work right, I am all ears. The Latest version of opengd firmware works awesome in simplex mode on the hotspot.

I asked you some details (MMDVMCal, freq offset, etc), but you never replied.

I have two gd-77s with the open gd firmware loaded. i can listen with both radios and sometime the receive will be garbled or the meter shows incoming signal on the radio and can't hear nothing, but hear fine on the other one. they will switch back and forth and sometimes both go quiet or get garbled. this is during a duplex setup in pi-star. both radios work perfectly if i set up my duplex hotspot to simplex.

What tools do you use. Give me some ideas please! My other Radioddity GD-77 receives same conversation just fine.
Did the radio with OpenGD77 also work fine on the hotspot before? If so maybe you've lost calibration in it itself or just need to tweak it.

Reference oscillator tuning in OpenGD77 is what you'd want to adjust.

You should also calibrate your Hotspot as well, as they are rarely exactly on frequency. This page explains how to do it: http://www.k9npx.com/2019/02/hotspot-of ... ation.html

Just try to keep in mind that you want correct calibration, not "matching" calibration. In other words try to make it output on the right frequency not just tweak it until it works on one radio. Start with the OpenGD77 radio and the Reference Oscillator.
Where do I find the settings for that? I have never seen it in the open gd firmware. Very interested in getting these radios working duplex. Thanks for the input

Hmm, for some reason I thought it was right in the radio, or used to be, but I'm not seeing it. Maybe it's just in the CPS.

Reference Oscillator adjustment is in the calibration screen in the CPS

None of the factor calibration can be changed directly by the firmware

The CC-Filter is removed - see viewtopic.php?f=13&t=2132 :
..We are aware that removal of the CC Filter , so that a Stable version could be produced and released, is not ideal for some people, so we plan to return this feature if we can make it stable...
