Ummmm you will really be better off with a scanner ... Unless you are a member of the VFD, and have paid your dues vias training, and are qualified to use an actual radio, your asking for trouble by buying one on the market. If this system is an ASTRO-25.. you can't just monitor the system on a radio.. it will auto affiliate and then be killed by the sys admins. If you are getting one to monitor an regular ASTRO system, unless you are really sure of what your doing with programming it, or have an expert friend program it and set it for TX inhibit, and other features.... you are again asking for trouble. There are no Chit Chat With Joe Public chans/TG's.... FD Comms are for just that- Official FD Comms.
When I was in SC, I purchased my own XTS3000-R Model III and had it programmed for the agency I worked with, with the mutual aid, and interop TG's of course. It cost me $2,500.00 for the radio. Right now it sits as a paperwieght, but I never know when I may find a need for it, or I may have it reprogged to use as a backup radio for the VFD I work for now. When your issued a HT, and or Mobile by an VFD, your not keeping it when you leave them, its not YOUR radio per say, unless they have an option for you to buy it. You may buy your own extra radios, but as stated, these are not for fivolous Chit Chat... Trunking Radios are not fancy CB's.
Yes, FCC + I would have a new home without a scanner

. I just want a simple one & RADIO SHACK says [on there web site] that it is programed with the local fire/rescue & police (900 Mhz) & it has a weather radio built in & a PC hock up [why a PC hock up unless it has the stuff in the CD like;
154.160 7A & so on
& all you do is plug it up & then the information from the cd will go on your scanner, but the instruchions will tell me.].
I just want to liste to the POLICE + FIRE/RESCUE so in when they say go to 7 C or another channel, I can listen in to them. I in no way want to us it for trouble. Also [if allowed] it will come in handy when I am on the road with dad & stepmom so if there is an accident on the road we can go another way. That is all I want it for, just for listenig.
As has been stated, unathorized communication on a TRS will cause magor headaches. [FCC & jail] Seems that the members on this site actually should do a lil more reading of the threads as this has been covered time and again. See the plethera of threads in the Trunking Forums.
