[DeathValleyDazed]

i'm not a HAM radio operator but my brother has been one since 1966 so I follow it once in a while. BTW here's a Wiki on what HAM is about:

I came across this video about Wilderness Survival With Ham Radio and was wondering if any of you or your friend or the NPS staff have embraced this technology while in Death Valley National Park. Next time I'm at the Visitors Center, I'll enquire.
