Set PTT with Terminal or Script


Recommended Posts

Hello Everybody in the forum!

I am a Ham Radio operator maintaining RF gateway for 2 years now, using Mumble on Raspberry Pi 2,

now on Raspberry 3. I am using VOX interface to key up the PTT pin of the radio. Well every Ham knows the behavior of the Radio Gateway using VOX Interface. And I am very excited when I read the discussion, suggestion etc... on this forum. Hoping that somebody in the forum send me a link the working Mumble Client with ptt keying, and input squelch keying. Please pardon me, I don't have knowledge on linux or software development or some kind, but little knowledge in electronics.

I see this is a old thread but I will ask this question anyways. I am looking to use Mumble in a similar fashion as Stephensworld is. With the exception that when the application has audio someone is talking. That a html command would be sent to a external relay to key up a radio. And the opposite when no one is talking. Disable the relay with another html command. Seems like this should be possible with the script function.
