comes with
5 radio cards (302.50 X 5 = 1512.50)
1 I/O
1 phone patch (165)
asking price $1300 USD + shipping
Project fell through so we are sticking with what we have now
so you are getting the whole controller for less then the radio cards and

Pac-rt or Pack Rats are they are called, is a low-powered repeater which
is tied to the main mobile radio in a police or fire vehicle, when the

John, I experimented with that once, and in some situations, it's the most

Echolink provides COS signaling, so I don't understand why someone would use

To clarify, I use the delay to keep the echolink node from decoding
DTMF from the end user. The controller regenerates necessary DTMF to

My agency's problem was a little different.
We operate on a conventional UHF repeater system.
At the time we had Micor mobiles.
Call would go out for a crash.
First unit in would be taking to dispatch fine.
Pulls his portable and is talking to dispatch through the PAC-R/T and the radio

Maybe it was another manufacturer? I know some of them had longer drop
times and longer durations.
