[arm-allstar] URI - Kenwood TMV-7 Hookup

[Ron Wenig]

John,

I couldn't find a setting to change pin 6.  My Kenwood TM-V71 has a 
setting for pin 6 for SQL, OFF, SQL TX, and BUSY.  SQL seems to work 
ok.  I guess with the V7 you just have to turn the squelch knob up 
pretty high so the radio doesn't break squelch.
