I am currently scanning a couple P25 systems, and about 4 sites. For whatever reason, one or more sites randomly lose signal, then come back. My scanner is not moving, so I am wondering what the cause of that is.
Any chance you have a priority mode turned on?what the cause of that is.
I'm 2.7 miles from the one site that is giving me problems. I don't have any priority or weather scan happening.Any chance you have a priority mode turned on?
Weather or Close Call or other Priority modes?
Check the display carefully when the signal drops out.
If not, chances are you are too far away from the transmitters.

Is this the system you are trying to monitor?I'm 2.7 miles from the one site that is giving me problems. I don't have any priority or weather scan happening.
It's just that the signal bars vary every couple minutes. I did not realize that that was normal. Thanks for your helpAre you looking at the signal strength meter and seeing the signal drop then come back? If so, this is normal behavior - it is part of the scanner "cleaning house" before it does its thing again. Nothing to be concerned about.
If it cuts in and out during a voice transmission and there are no priority things going on as described above, I concur with Simulcast Distortion.
Good deal. That specific site is not simulcast, so as already noted, you're likely seeing the house cleaning.I am scanning the PA STARNet P25 System, specifically the Allegheny Region Simulcast on the WEST03 tower
There is a cell tower on top of my hill 6 tenths of a mile from meCould it be because of a strong nearby cell tower? When the cell signal is active, reception from the intended site goes away.
The word simulcast is literally in the name of the site. WEST03 is one of five subsites making up the Allegheny Region Simulcast cell.Good deal. That specific site is not simulcast, so as already noted, you're likely seeing the house cleaning.
Multicast?There’s another term (which eludes me) that acts much like simulcast but isn’t. Hopefully, someone here will have the answer to that which eludes me.
There was another called Anycast as well. Or... I could be confusing multicast and anycast! I's been a while since it was on the air plus my brain is foggy from those days.Yes, multicast. Thanks!
I'm not confused at all, and I'm fully aware of what "simulcast" means, believe me.There’s some confusion about the term simulcast.
Simulcast: multiple transmitters/sites all broadcasting the same transmissions on the same frequency/frequencies simultaneously
