This is a motorola Maxtrac setup as a remote base listening to a certain repeater which is setup for "TX PL on Input Only" through the radio club. The repeater is a tad bit slow on it's Transmit CTCSS turning off however, so it sends a bit through the network when the remote base unkeys.
The repeater would have to be a whole lot longer than "a tad bit slow" to turn off the PL encoder. When the PTT goes inactive, the Maxtrac sends reverse burst and then unkeys, a process which takes on the order of 200 ms. During that sequence, the repeater should have recognized the reverse burst and closed its squelch and concunrrently stopped encoding PL; both of those actions should have completed before the Maxtracs transmitter even drops. If the repeater is still transmitting PL by the time the Maxtrac transmitter has unkeyed PLUS the time it takes for the Maxtrac to switch back to receive mode (takes a bit of time for the PLL to lock) PLUS the time needed re-aquire PL decode again (and Maxtracs are not great performers in this regard), then something is wrong with the logic at the repeater as it would appear it's encoding PL MUCH longer than it should be - by several hundreds of milliseconds at a minimum. Fix the problem at the repeater. --- Jeff WN3A --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
