[Elecraft] NVIS HF vs VHF line-of-sight & CB in 9.0 quakes

[Stanley Petrowski]

Thanks again Don. I'm working on that.  I agree that this skill set is 
fast fading. One of the interesting aspects of the ham circles I am 
affiliated with is that we are all well over 65 and most beyond that.
I have secured many hundreds of feet of good quality coax, spools of 
wire to build traps and more wire to use for building antennas. In the 
end it is all part of a huge learning curve and skill set development. I 
devote what time I can to it all but confess there isn't a lot of time 
left. I am very impressed with what antenna tuners can do and sincerely 
hope I don't blow the finals on a stupid experiment.
