What does Dec/Hex mean?

[tvengr]

Talkgroups on a trunked system are equivalent to frequencies or channels on a conventional system. Each talkgroup has an ID (TGID), the DEC number you were inquiring about. You will hear whoever talks using that talkgroup, just like would hear whoever talks on a certain frequency on a conventional system. If the talkgroup is Fire Dispatch, you will usually hear both dispatch and the units responding. Dispatch will advise units to switch to a Fire Tac talkgroup. On the Fire Tac talkgroup, you will hear the activity at the fire scene using that talkgroup. Even though the frequency constantly changes on a trunked system, everyone using the same talkgroup stays together. The problem with simulcast systems is that the control channel of a site is transmitted on the same frequency at the same time on multiple towers. The signal from each tower arrives at your scanner at a slightly different time, degrading the scanner's ability to properly decode the control channel of a trunked radio system. That results in missed transmissions and garbled audio. If you are close to one tower, the signal can override the interference from the other towers. The Uniden SDS100 handheld and SDS200 base/mobile are the only 2 scanners designed to receive simulcast systems.

Thank you so much for the information and even scanner advice! I plan on buying the SDS100 from the bearwarehouse just I am skeptical on if it’s trust worthy and how do I program a TG into the scanner

Here is the link to Sentinel, free programming software supplied by Uniden. Go ahead and install it on your computer while waiting for the scanner. I have had good customer experience with Scanner Master. BCDx36HPSentinel < UnidenMan4 < TWiki

alright. Thank you!

Hey I had a question about the interference part. So lets say someone is talking on TG-727 then a unit on TG-729 needs to transmit will they still not be able to transmit or will they just get assigned an available frequency? Or would the unit on TG 729 have to wait until the unit on TG 727 is done

TG-729 will be assigned an available frequency.
