One of the radio hobby's most knowledgeable scanner monitors, Alan Henney reported overnight (2/21) on the Scan-DC newsgroup that he has found a new three channel EDACS trunk system in the Washington DC area. Alan theorizes that his new discovery is a US Navy trunk system and it has been on the air for the past year or so. He noted in his Sacn-DC post that unlike the Naval District Washington (NDW) EDACS system that operates in the 138-150.8 MHz frequency range, this new system is all digital.
Frequencies:
138.2375 LCN01
138.6125 LCN02
138.7125 LCN03
All three frequencies are dedicated trunk system frequencies under the new narrow band 138-150.8 MHz band plan that DoD is transitioning to. If you have any additional information on this system, please drop me some email at larryvanhorn @ monitoringtimes.com.
