Well, I have it all connected and running, coming straight out of the Doug Hall
voter. Audio is fine, TKR-850 is sending ID's as programmed, everything is OK
except one item: I have no squelch tail (carrier delay). The system keys up and
down exactly within the timing window of the mobile user. Is there anyway for
the TKR-850 to add back a carrier delay operating in Duplex mode, rather than
Repeater mode?
