I am having an interference issue from a IDAS repeater that sends out a beacon every 15 seconds. I'm told that this beacon is for RSSI. My question is...can the time be changed to say 15 minutes to help reduce this problem. It's less than 1 meg away from the input to an analog repeater on the same tower and kills the reciever on the analog repeater.
Really need more specifics. But generally ...
IF this is a multisite or trunked system, the beacon's RSSI allows mobiles to select the optimum site to associate with. The greater the duration, the less signal mobiles have to work on, and the more likely a mobile will move into a null zone without knowing it should look for a better site. Not hearing a beacon within the defined time range (or hearing a beacon with the RSSI below the programmed re-vote trigger strength) will cause the mobile to look for a better home signal.
IF this is a single site non-trunked system (plain repeater), the beacon is not necessary at all (unless the mobiles are set up to alert the end user that they are out of range).
That said, if the beacon wacks out another co-located receiver what happens when the IDAS repeater is active (someone is talking)?
1 MHz is a long way off in terms of filtering, so adding the right TX filter and RX preselector shouldn't be any issue at all. VHF 2-Meter amateur rigs run on 0.6 MHz splits by default. UHF would be a little tougher, but still quite do-able. It could also be an indication that the filters (or duplexer(s)) are out of tune.
Sounds like someone didn't do their site engineering before throwing up another transmitter.
