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

[Don Wilhelm]

Stan,

Turn the power down while experimenting and you should not "blow the 
finals".
I am 77 and still learning, so age is not an excuse.  It is never too 
late to learn.
Besides, it exercises the brain which is known to provide a hedge to 
dementia.
That is why I am still repairing Elecraft gear.  Each problem presents a 
unique challenge and keeps my brain active.

73,
Don W3FPR
