[arm-allstar] Radio Squelch

[Ron Wenig]

Hi Doug,

You nailed it.  I have a Kenwood TM-V71 and it looks like it is working 
correctly.  On the V71 you can set Squelch Control Output on pin 6 of 
the data connector.

Off - SQC output remains inactive
Busy - When signal received SQC output becomes active
SQL - While CTCSS is on SQC output becomes active when matching signal 
received - CTCSS off SQC output becomes active when busy signal is received.

It seems on my other radios you can't set this (there's no menu option) 
so the COS follows squelch.
