Re: I7SWX PTT Pop Mute

 

I used a 5v arduino relay module. with 1 normal open ?and ?1 normal closed contact.
I used the normally closed contacts so there is audio in rx mode.
When tx occurs the contacts open.
My power source for the relay activation comes from a tx led mod.


The best is a reed relay?
