Ok, now that I stripped all the darn yahoo HTML crap ... here is my answer to the reply.
1) If you have old firmware .. buy an upgrade! 2) (the simple solution) - Check your programming on your channel information screen. Make sure repeater activation and repeater hold in are set to "Carrier and PL". If hold in is set to Carrier, that means that anything that may false the decoder (even momentarily) can hold the repeater open. In the RSS alignment system, set the system squelch up high enough so that it is not constantly open (most of my experience with Quantars between 150 and 800 MHz states that you will see a minimum signal strength of around -120 to -124 dBm on most properly tuned Quantars). Hope this helps! James Holben SINAGA wrote: > > Dear Quantar expert, > > > > We have this annoying problem where the receiver squelch opens up on > the Quantars and is retransmitted.
