no audio from MMdvm hat

Post by m0hms »

Hi trying to set up this pi hat, the lights come on ok when it is supposed to be receiving but ive no audio and when I key my radio it does not activate the Hat.
When powered up the sync light is flashing and to all purposes looks like it should work.
This is the log ive downloaded can anyone spot anything wrong please :

Hi

Its a simplex hat on 434.000. Ime in the Uk

Ive run MMdvmcal and it gives me an offset on "0"

The hat supplier says RX offset is -475....this makes no difference.

Convinced its a duff hat.

Hi
My radio is fine it works on another hat with no issues, Ime getting no audio out of the hat and when I key up the radio the hat does nothing.
Again if I use another hat and same radio all is ok.
Its strange to me that the oled screen shows the mode ime in ie DMR or Fusion etc...it just seems to be the audio side thats not working.
Its bang my head off the wall time as ive been at this for 2 days nows and ime no further forward.

Sorry just read what you wrote about "m" no the radio does not go into TX when I press the space bar.

Thanks for the help.
