Pages 8 & 9 of https://ftp.nifc.gov/public/incident_specific_data/eastern/Michigan/2012_LittleMackLake_MI-HMF-120089/ICS_GEN_STAFF/IAP/IAP_ 04292012Day.pdf has some forest net frequencies.
Back in 1987 I worked for them when I was living in oscoda. There main dispatch back then was 169.925Does anybody have frequencies for the forest service Huron-Manistee national forest?
Try changing the CTCSS to the existing frequency 169.925Mhz to 110.9. The few times I hear it, up here in the UP, and monitoring the talk it indicates that it is Manistee National Forest. Might be a starting point for ya.
Dnr is different from the usfsMPSCS: State Department of Natural Resources talk-groups
Ahh hitting my brain now. 170.525 was a fire ground freq. Talk around. But like I said, that was in 1987 lolIn my limited Notes [2016] for that Freq/Tone it should be the Admin Net, WEST Repeaters
170.5250 156.7 might be Admin Net, East Repeaters
