PTT for T?R control

David Turner
 

Hi Sherrod.

As David said when you click/tap screen ptt button, light on odyssey ptt should come on.
When light is on voltage on pin 8 of db9 socket goes high to 3.1 volts.(measured between pins 8 & 9 ).
BPF0 BFF1 BPF2 BPF3 go high depending which band is selected.(more than one band)
Also Ant sw pin 6 goes high when ant 2 is selected on Quisk screen.

Hope this helps.
Dave.
