• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Well, the title pretty much says it all. While monitoring the Mesa/Gilbert Fire FD1 dispatch talkgroup, whenever a dispatcher is talking I hear the first few seconds of the transmission up through the assigned units, and the radio begins to cut in and out while they broadcast the type of call and location. I am using a Uniden BCD996XT monitoring from Gilbert. Any help/tips are appreciated.

Probably the same problem all scanners have with simulcast P25. You can try to resolve the issue by moving the antenna around until it goes away or just listen to them on the VHF side I think it's 154.3400 for Ch.1. The 800->VHF patch won't be around forever, but it should still be up.

Another solution is to mount an external yagi antenna so that only one site antenna gets gain to the scanner while other sites are attenuated. This will require getting a map of the sites, then looking at the radiation (reception) pattern of the antenna to see how you can point it to make one site come in as strong as possible in relation to the other sites.

Plot out your location and the location of all of the sites. If it looks like you can do this in your situation, you will be pleased with the results. I did it in my old home, and the results were outstanding. I went from what you got, to 95% reception. Now keep in mind, this WON'T always work. If any direction you point there is more than one site somewhat in front of the antenna, you are out of luck, as I am now in my current location in Buckeye trying to pick up the RWC signals. From my location, all sites are relatively in the same approximate direction, so I get what you get, garbled bits and pieces, which means I now just monitor nearby stuff (luckily I work right beneath a simulcast a tower and get awesome reception at my desk at work still).

On a recent trip to Mesa, I noticed that there was a sweet spot right near the big comm tower at the 60 and I think Dobson (not sure). If possible aim for that one and hopefully the other sites are off at different angles.

Good luck.
