MMDVMHost FM Mode

Post by DC7JZB » Sat Jun 11, 2022 12:20 pm

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-Funknetz" https://fm-funknetz.de/, with the GD77 as Hotspot.
This network will work with Talkgroups, like DMR, on FM-Repeaters with SVXLink. Still a nice Thing. ;)

Hi,

I think you misunderstood how MMDVMhost supports FM.
You need a real MMDVM controler running the full MMDVM firmware for this (and all the transceivers, etc), not a hotspot modem.


Cheers.

Neither the GD77 or MD9600 types of radios have a signal path from the microprocessor to the FM RX or Tx hardware.

So it is impossible for these radios to perform the functionality you describe
