[NLRS] Introduction - Thomas WN1C

[Thomas Murphy]

Thanks for the IJV firmware reference! That looks usefully complete with 
the addition of the chirp-next interface module for PC memory 
management. I might give it a spin on the all-mode options with my 818 
as communication partner.

There was a clip on Youtube showing that firmware with 23 cm transmit 
does show a measurable output, but only a small spur on the spectrum 
analyzer. With any luck, a "little" transistor re-tuning and filter 
replacement can do better than that for some decent power out (a watt or 
two, I expect).

Good luck on your build! The series of radios certainly makes for a low 
cost option including as exciter.
