Re: DCDM and SFR

Hi! I tested GD77 with orig firmware about a year ago together with Anytone 578/878. The DCDM feature was barely usable, GD77 had problems to maintain the time slot sync, it often drifted in time and started to interefere with the 2nd timeslot (generated by the Anytone radio). SFR feature (operated ...

Re: No comm port to select in GD77 CPS

OK well somehow finally managed to get it to work. The firmware has been flashed, now the rig has a screen saying Settings update OK And a green flashing light on the front of the rig. Do I just wait for it to finish doing whatever it is doing? No, it's just an informational message, that the firrm...

Re: GD-77 promiscuous again?

Sorry if it has been asked before.. but guess that's why I ask it in this group. I have a 'local' repeater programmed with some Talk Groups that I found on the Brandmeister website. For the South Texas TG I know I am able to hit the repeater as I can also see my self in the Last Heard list of the r...

Re: OPENGD 77 RAS

Its still illegal for Amateur Radio use regardless of whether its technically encryption or not I think it depends. We don't know exactly, how is it working. If it just adds some special info (PDU or something similar) to the otherwise intact DMR stream for checking and conditionally opening the ra...

Re: problem with simplex in dmr

It's also very time consuming to reverse engineer and implement features not generally used by Amateur Radio operators These sort of features literally take hundreds of hours of people's spare time to get working, so unless one of the developers has a personal interest or need in this sort of featu...

Re: Fecskebeka

Have a nice day! Hi Daniel! Yes I tried the DMR filter "off" mode. I know when that so works. I didn't make a long video of it. Be as you say. But then you shouldn't be physically able to logically just select the CC mode "off" state! Because thus the display selection logic is faulty or the DMR de...

Re: Larger memory

Hi Pavel, Well, it's easier to desolder SMD components with a hot air station, and quite mandatory with multipins packages. Cheers. --- Daniel Hi Daniel, thank you for the photo. It looks doable :-). I use a "desoldering wire" for removing most of the solder and then I obviously use a sharp needle ...

Re: Larger memory

Hi! Could anybody who did this mod post the photo ? I would like to decide, whether to risk doing it. My soldering skills are more trained on classic electronics than on really tiny SMD. On the other side, I have a relatively good Weller station with perfect temperature regulation, and with relative...

Re: DCS D036 not available

Maybe I’m confused. Whose standard does openGD77 follow? Motorola, Yaesu, Icom, Kenwood, Baofeng, TYT, all have 36 and 036 in their DCS. And the RD5R even had it in there as a DCS. When I lookup Digital Code Squelch those are listed there as well in the group of codes. The firmware don't follow any...
