Stable release (2022 02 28)
Re: Stable release (2022 02 28)
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.linkford wrote: ↑Thu Mar 17, 2022 2:23 amSwitched the duplex hotspot to simplex mode. works perfectly.

Re: Stable release (2022 02 28)
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.F1RMB wrote: ↑Thu Mar 17, 2022 5:49 amI asked you some details (MMDVMCal, freq offset, etc), but you never replied.linkford wrote: ↑Thu Mar 17, 2022 2:23 amSwitched the duplex hotspot to simplex mode. works perfectly.

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.

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.

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.linkford wrote: ↑Thu Mar 31, 2022 8:22 pmWhere do I find the settings for that? I have never seen it in the open gd firmware.

Re: Stable release (2022 02 28)
Reference Oscillator adjustment is in the calibration screen in the CPS
None of the factor calibration can be changed directly by the firmware

Re: Stable release (2022 02 28)
hello, in new version miss CC filter in quick menu. Is possible to add ? Thanks
Re: Stable release (2022 02 28)
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...
Re: Stable release (2022 02 28)
yes, i know about this, but missing when i need turn off CC filter.
