My most recent information 2010 is that Mt Rainar and other Natl parks and DNR,USFS in western Wash. now have their dispatching done by the Puget Sound Interagency Coord Center in Everett. Mostly the have tied into the legecy radio systems of the agencies they serve. For Mt Rainar my information is:
169,7250 Main Freq uses several input freq and tone around the MT.
168.6125 Common 1 Simplex
168.7125 Common 2 Simplex
They use a number of repeters around the parl. all use the same output just differant inputs and tone.
I live in Everett and can hear the crystal rept very clearly. Lots of action on the 11yo drowinig on the White river side..
