I think Tim's explanation makes a lot of sense... I will try to confirm with the Summit Sheriff in the next few months.
And yes, there are other groups that use both the VHF and UCAN, but in terms of traffic, I think they are mostly using the 800mhz freqs now.
Rolfman:
"Parley's Canyon Site 13
Strawberry Peak Site 21
Lewis Peak Site 22
Summit Co. Site 24
Clayton Peak Site 26
Wasatch Site 27
Current Creek Site 28
Also now using 866.9375 as their Control Channel?"
I can confirm that Lewis and Summit are down -- but I will have to do some tests for the others -- perhaps with an outdoor antenna to be sure.... perhaps Junior1970 has already done that...
I only have a couple new TG's that I feel I have ID'd correctly -- let me do some more work before posting to the DB. (Much easier to sit back and listen, like the lazy person I am, than do investigative work!)
On another subject: There will be a Red Cross 'Planned Emergency' the morning of September 12th in the SL Valley. Among other things, they will:
"Test the Red Cross commuinication systems and use the trunking radios and famiiarize with their operations and function".
I'll be there, as part of ARES, using one of their new, trunking HT's
Don't ask -- I don't know anything more about their trunking -- TG's, etc. Ham repeaters will also be in use -- If you want to monitor, try 146.700 Ensign Peak, 145.490 'voice from Tooele' Much of the exercise is secret -- which is the purpose of the test -- The 'event' will happen mid-morning, the test should be complete by noon.
