Now that the Palmetto-800 conversion to P25 has been completed, it is possible that this site may now active, possibly simulcast with site 103 in Seneca. Can you check site 065 again to see if it is active?
Site 2-65 is one that hasn't yet been listed because it didn't show up in the neighbor/peer lists of any of the other nearby sites.
I wouldn't think that it's a simulcast site of the Seneca site if it's listed with a separate site number and unique set of frequencies. Callsign WQSL478 would appear to correspond to that location and set of frequencies.
If I had to guess, I'd say it's a new site that is still being built out. It is likely intended to improve coverage in the far NW corner of the state/county which is very mountainous. It probably hasn't been connected to the core controller, which is why it doesn't show up as a peer, and doesn't show any peers, and doesn't carry any audio traffic. Perhaps those repeated call grants on TG 65536 are used for range testing.
Thanks for posting, and keep monitoring it. Let us know if something changes.
Motorola ASTRO 25 systems at system release 7.16 or later broadcast a continuous "Digital ID" BSI (Base Station Identification) on the control channel, as well as on the voice channels while they're active and during the hang time at the end of the transmission. It's transmitted as an integrated part of the normal data stream.
65536 is a dummy talkgroup ID that Unitrunker uses to represent BSI activity.
