I have built a allstar/echolink  Raspberry Pi 3 node that I can travel with and use in hotel rooms with minimal components. I have a Verizon hot spot that I have been able to successfully login to with the RP3 that I can use while traveling so I don’t need to utilize the local network. I have a sound card and a headset/mic combination that works well.

I would appreciate a little help to get the GPIO configured so I can hook up a momentary contact to trigger the PTT.

Equipment list:

Verizon WifI

Raspberry Pi 3

USB Sound Card

Headset/Mic

Momentary Contact Switch

Thank you in advance,

Billy
