According to the ODOT Channel Names document here is the new ODOT simplex channel plan:
Red - Statewide All Districts
Green - Statewide All Districts
Orange - Districts 2C, 3, 5, 8, 10, 12, 13
Black - Districts 1, 4, 7, 11, 12, 14
Yellow - Districts 2B, 4, 7, 9, 11, 13
Gold - Districts 3, 5, 8, 9, 14
Gray - District 1 Only
Pink - District 2B Only
Hood - District 2C Only
Tan - District 10 Only
District 4 Albany and District 7 Reedsport both use 151.0400 131.8 PL so that might be Black or Yellow. District 4 was using 151.0850 131.8 PL before the narrowband switchover but now that freq is silent in Albany...so other districts' simplex freqs may have changed as well. District 5 uses both 151.0700 and 151.0850 both with 131.8 PL tones so those could be Orange or Gold.
Does anyone know what Red or Green are? I have every frequency licensed to ODOT in my scanner to try and figure some of these out. I know ODOT simplex isn't exactly a hot topic but every once in a while there's something interesting. Plus its kind of fun to listen while I'm stuck in road construction.
