System Notes

Some (if not all) of the users of this system appear to have moved to the 800 MHz TETRA trunked system (WNAJ329)

Additional Programming Information for 396/996 XT Users:
***Choose Band Plan 1 Only***
LOWER BASE: 476.5000
UPPER BASE: 481.2375
SPACING: 12.5 Khz

Unsure if system ID is 413F or 913F. On 2/7/08, a listener reported that his 396T showed a system id of 913F, so 413F is likely a typo. A May 2007 CARMA post confirms that 913F is correct.

Brooms, Sanders, Salters, plows, snow units and Vamma's are now on this system and no longer on the city 800 MHz system.

240--Snow 2. This has also been used during the recent visit of POTUS as an Escort-Secret Service talk channel in the clear-not encrypted. Jim
