I've got an MFJ-393MK headset with the MFJ-5393MK 8P modular adaptor for the TM-D710. The adaptor requires a PTT switch via a 1/4" Audio mono plug (2 pin). The 5393MK didn't come with any schematics.
For the PTT switch, do I just wire a normaly open switch that closes the two pins on the 1/4" mono plug when pressed?
I've looked online but my googlefu was weak last night. I'm probably overthinking this but don't want to smoke anything by making an assumption.
Thank you for any input on this.
