OpenGD77

Hi, Tetra ? The HD1 is also a DMR HT. Cheers. --- Daniel Daniel, as far as I understand, Mario tries to tell us - if there are any very strong TETRA stations around, the GD77 can not be used on any channel, due to RF overload in the receiver. But the HD1 can be used in FM without any problems in th...

I don't know how they do it, but I have many Places here in Berlin, with big powerfull commercial Tetra transmitters where I can't use the GD77.
In FM only Noise and fully S-Meter Scale over the Bands, no Decoding of DMR Signals.

And the HD1 works like a charme at the same Places.

Looks like retevis is developing the Ailunce HM1. This could be the radio set in Ailunce first car, possibly DMR-based too.

Yepp, since 2 Years.
And they've promised that it will be fully compatible to the HD1.

I think they don‘t will discontinue it so fast. :mrgreen: I saw several Informations to the HD1 on OpenRTX. https://openrtx.org/#/hd1 But I don't have the skills for programming. :cry: The HD1 is definetly the better Radio. Louder and better Audio, no Blocking in the Receiver, when there are big Sig...

Is there a way to enable the MMDVMHost FM Mode in the Firmware of the GD77 ? This will be usefull to use the GD77 as a FM Hostspot, as example for SVXLink. At the Moment the MMDVMHost says "FM enabled in the Host,but not in the Modem Firmware". I'am interested because it will be nice to work the "FM...

Thank you.

Looks like you're Right.
I Have activated the CC Filter on the Version from 20. March and no Change since the last 15 minutes.
I will try you're Version next.

Thanks for it and 73 de Mario

Since the pull of March, 20, the Color Code changes when the Hot Spot is running.
It starts with CC 1 which is default in my MMDVM.ini, but after a couple of Minutes of running the GD77 is switching over to a different Color Code.
This will be every couple of minutes.

Is there anything I'am missing ?

After a couple of minutes, the Hotspot freezes and Shows TG 0 in Display. If I Transmit with a second Radio, the TG 0 goes away, but there is no other reaction from the Hotspot. If I try to Restart the MMDVMHost it doesn't find the GD77 anymore writes "can't read Firmware after 6 attempts" and Close...
