"Waving Off"
JFish said:
A lot of what you say does make sense, but I know from use of my radio that affiliates with Greenwood site it will carry ISP-52 traffic
The radio will affiliate with Greenwood, but is it getting the ISP-52-DISP traffic on Greenwood or is it being waved to another site when receiving traffic on that talkgroup?
The reason I ask is this. I tried the experiment today I mentioned in my post above; looking for confirmed radio IDs affiliating with Greenwood that I know from listening and logging are in use on ISP-52-DISP (i.e. radios that are used by 52-XX units). How do you figure that out? Easy. Just run Unitrunker, and when somebody keys up on any given talkgroup, listen to the unit number, look at the radio ID being displayed on the screen, and then append the user's unit number in the label for that radio ID.
This experiment wasn't real hard to do. I just let Unitrunker run a log on Greenwood all day long. 55 megabytes for just under 10 hours of log - that's a lot of text! I then used Wordpad's find function to look for the confirmed radio IDs in the log file. I found four confirmed radio IDs being waved off by the Greenwood site when trying to affiliate. I don't believe there's a way to tell what group those radios were trying to affiliate with when they were waved off by the site (meaning I don't think it shows up in the outbound control channel data), but you could probably correlate times with logs from other sites made during the same time frame showing those radios making successful affiliations on the talkgroup on those sites but being waved off by Greenwood.
In the control channel data stream, the system is constantly sending out information for the subscriber radios to use in locating the control channel of adjacent sites to the site they are currently listening to. Radios roam from site to site all the time, and if a talkgroup isn't permitted on a given site, the radio should move to the next adjacent site with the highest RSSI on the radio to get traffic on that talkgroup.
Perhaps even more significant than the radios being waved off is that in just under 10 hours of log, I did not find one single channel grant for ISP-52-DISP, which would show up in the log as "1060 G" followed by voice channel and radio ID information. Logic would tell you that for a site that's pretty much centrally located in District 52, you'd have at least a few radios affiliate with the talkgroup on that site, and have at least a few channel grants in a ten-hour period. Not so. I am really thinking the talkgroup is, for whatever reason, not permitted on that site.
Here are the excerpts from the log:
