Question about the APS TRS: What site is best to listen off of when living in Phoenix area? I have given this system a try and have not heard anything yet, and looking at the database info, the towers seem REALLY far away for me to be able to pick them up here but PHOENIX_SCANNER seems to be able to. A little help?
Are you not hearing anything because the system is quiet or because you can't even hear the control channel to track the system? These systems, like other TRS systems, require you to be relatively near to the intended use area.
Then there are reception holes that happen for a myriad of reasons. For example, the Mt Lemmon South tower can not be heard along the foothills of the Catalina Mountains, nor to the NW of Tucson, until you get past Marana. It's a pretty big hole :<
I know the systems up there are pretty active. I have them plugged in when I make the trip up there. I haven't been disappointed with hearing traffic, BUT, I must say it will normally not be exciting. Normally you'll hear power company type communications without any real flare
There are still a number of towers throughout the state that we have not identified the control channels for yet. Help is always appreciated by submitting the data to us to update it on the APS page. If you do submit, please ensure the ID is correct. You will notice that some neighboring towers use the same control channels :< It'll be important to verify the transmitting tower ID.
