Up here in Alaska we (Alaska Air National Guard) monitor 121.5 and 243.0 from all the FAA and military RADAR and Communications sites in the state. Small aircraft are used to supply the numerous villages and small settlements with goods and mail on a daily basis year around weather permitting. The right radio could really be a life saver in this environment. I am going to do some radio research using what I have read in these postings. It seems like a good investment in safety.
