Thanks for the info. Most locals here in Washington County that have had their scanners over the last twenty or so years have never even heard of a trunked or digital system. I'm sure that in a few months when the switch is made... there will be a lot of people trying to figure out what to get and how to program them.
I'm lucky enough to have one of the new FD handheld radios and I think the new system will be a lot better than what we are using now. If you guys have any questions you think that I can help answer, let me know. Also, let me know if i'm "crossing the line" by providing info on our new system. I've been scanning for years, but now have been issued a radio to use and never really have looked into what "legal" issues might pop up now that I actually have a radio.
You are not crossing the line legally. The only way you would be doing that would be if you were giving us encryption keys, and I doubt you or anybody in Washington County will ever have access to those. We don't want or need them anyhow. However, ethically, it may be a big no-no within your department or agency to provide talkgroups or other radio data from your radio. That should usually be left up to the chief or public information person. That is why it is entirely up to you whether you provide the talkgroups to us or not. It is your job we are talking about, not ours.
That said, if you decide that you want to "discover" the talkgroups, their decimal number as shown on a scanner, and their corresponding "alpha tag" or channel name and use, here are two methods I have used.
1. Scanners such as the GRE PSR500/600 come with a programming cable, and free programs such as Unitrunker, which is available for download in the downloads section of radioreference.com, are available to read the control channel data from the control channel. In the Brenham tower's case, this frequency is 774.44375. When parked on this channel, and having your scanner connected and monitoring the control channel data stream, you turn on the department radio. It will show the radio immediately being "affiliated" with whatever talkgroup you are on. For instance, if you turn the radio on to the Brenham fire talkgroup, it will show your radio ID "join" talkgroup 2516. If you change the channel, the next talkgroup will show up as "joined' by your same radio ID. You get the picture from here on out.
2. I don't recommend this at all. But it works. If you don't have a computer, you can key up each individual channel without talking briefly, and the scanner, provided it is not busy, or you have busy talkgroups locked out, will display the talkgroup and pass the silent key-up audio, and that will let you know the decimal number of the channel. Two reasons I don't recommend or endorse this option: A system administrator could notice that your radio transmitted on every talkgroup in your radio by looking at the radio logs. If a sudden plethora of new talkgroups in that range show up on radioreference at the same time, they have a good idea of who the culprit is. Second, it is a emergency radio first and foremost. You could be keying over somebody else who might have important traffic. You are a grown person, you can certainly use your head on this one.
Bottom line, we appreciate information from people in the know about radio systems. But we don't want you to compromise your job security or trust from your superiors by asking you to do something potentially harmful to them.
