Milt; I believe it was to change operation from PL operation to CS operation, not just receive, but 'repeat' also
IOW, change it to a carrier-in operated repeater Gary ----- Original Message ----- From: Milt To: Repeater-Builder@yahoogroups.com Sent: Friday, March 13, 2009 11:16 PM Subject: Re: [Repeater-Builder] Micor Card needed - TLN1251A The typical application is to be able to drop RX PL from the console. Not just to check for co-channel users (ie the monitor function which is reset by PTT) but to go to and stay in carrier squelch even when transmitting until commanded back to PL receive. Hypothetical example: The medivac helicoptor (or your neighboring mutual aid department) does currently have the proper PL for your county. Dropping PL receive lets you hear him transmit and you can reply to him. When the incident is over the PL receive is reenabled.
