Additional Raspberry I / O output

[I3YBD]

Goodmorning everyone

My request and for the PocSag part, is it possible to have an output indicating that the system is transmitting the PocSag mode as for DMR, Dstar, Fusion, P25, etc ...? On the Raspberry I / O connector ????

Thanks, Maurizio

Not really, since the Pi doest actually know what the MMDVM is doing, MMDVMHost knows this, but the Pi does not.

However, you may want to have a look at this:

You understand perfectly !!!

Maybe I found another solution but I have to add a Logic board, I saw that when there is a Pocsag transmission we only have the PTT command, when transmitting in DMR, Fusion, Dstar or P25 we have the corresponding PTT + Led Codec command, doing a logical combination I can determine which Tx I can enable for transmission, in Italy the Pocsag uses the Vhf frequency, the DMR uses the UHF, if you use a Vhf I can change the channel as the Link you sent me !!

Hello and thanks

If you need to swap between two radios, it may make more sense to run a separate radio and Pi, with the latter in POCSAG only mode.
