[Elecraft] NVIS HF vs VHF line-of-sight & CB

[kevinr at coho.net]

I live in Oregon's Northern Coast Range.  2 meters has the same problems 
up here as it does in the Southern regions.  Because most of the locals 
have CB radios it is how we communicate in an emergency.  The local 
repeaters are dead other than during net times or drive times.  If you 
really need help CB radio works much better than our amateur bands.  We 
also use it to avoid the many log trucks.

Please try NVIS on 40 or 80 meters.  You'll find you can cover most of 
the state with its use.  Plus the antennas can be ad hoc - tossed into 
trees or even an old fence line.

     73 & GL,

         Kevin.  KD5ONS
