[Elecraft] OT: Nano VNA

[David Gilbert]

There have been a couple of folks who have compared a legitimate nanoVNA 
to $50K HP lab equipment and found them to be virtually equivalent for 
accuracy up to their fundamental oscillator frequency (300 mHz for my 
unit).  The nanoVNA will work higher on harmonics with slightly reduced 
accuracy.

There are cheap knockoff clones out there, but the legitimate ones are 
VERY inexpensive (maybe $70 now?) and are not toys.
