Supplemental notes regarding the Twin City Communications LTR TRS. This system is a LTR Standard that can be tracked by any scanner that is capable of trunking LTR systems.

Frequencies

Site Name              
001 (1) Confirmed LCN01 461.200000 02 N/A 04 N/A 05 463.650000 06 N/A 07 N/A 08 N/A 
    09 460.875000 10 N/A 11 461.675000        

464.050
Was previously listed as LCN 07 464.05000

No LTR activity has been noted on the above frequency. The only usage is 464.050 107.2 PL with voice inversion scrambling. The license is for WPBX488 which is not licensed to Tucci Rentals.


462.500
No LTR activity has been noted on December 30, 2012. Testing was being conducted that day and only LCN 1, 5, 9 and 11 had activity leading me to believe this channel is no longer a part of the LTR system. Another reason being that the database lists Mitsubishi using that frequency.
