Title: DM4401e No sound or PTT
Post by: onmia on August 21, 2019, 08:35:05 PM
Hi All ,
I have a little issue with a dm4401e,
the ptt will not work on the mic and i have no sound from the front speaker.
I have tested the speaker and it is ok.
I can read and write to the radio ok ,
I can remote monitor the radio , so the mic and tx works ,
The EM button works on all channels.
It picks up the different channels on scan but no sound.
i'm stumped any ideas ???

Pop an accessory onto it - like a speaker mic

Any sound ?

Oh and any startup sound ?

was going to say, I've had a 4400 like that, was the speaker amp, board repair possible but not easy
