Is anyone a Ham radio operator? I'm wondering if there is a frequency someone could use to call for help if needed. Or it may be cool to listen into the SAR frequency. I'm sure they're within the restricted frequency range so people not involved with SAR couldn't transmit.
Yes. Check out my info at
http://www.qsl.net/aa6j/pct/for information on using ham radio in the backcountry,
then click on "California" for a list of repeaters that MIGHT help.
There's no guarantee someone will be listening, though. Also, in the canyons there are places you can't hit the repeaters.
Oh, if you mean HF ("shortwave"), yes, that's possible, but most don't carry that kind of equipment on the trails. The antennas are a hassle.
You can't talk on SAR frequencies unless you are authorized by SAR, and ham radios legally cannot do so anyway, but most will be able to listen in. Many SAR have ham operators on their team though.
For the Whitney area (hams will know what these numbers mean):
Best bet is:
146.760- (100.0) Mazourka Peak (Independence)
147.210+ Little Lake Linked to Mazourka Peak
Very helpful, harder to reach from Whitney Trail:
146.940- (103.5) Silver Peak (Bishop) Bishop Amateur Radio Club has a net every night at 9 pm which welcomes visitors
147.060+ (103.5) Silver Peak (Bishop) Bishop Amateur Radio Club
Not as active as 146.940 above.
Others in Central Valley if high on west side of crest:
147.240+ (141.3) Corcoran
145.150- Bakersfield
146.910- Bakersfield
146.760- Visalia
