[NJARC] Help with antenna tuner

[Al Klase]

Marty,

That would probably make it an NE-51 (1/25 watt) or NE-51B (bright 1/7 
watt).  I would not connect it directly across the output without some 
kind of current limiting.  I have a couple of low power military rigs, 
e.g. GRC-109 that use neons for this sort of thing.  They're just light 
capacitively coupled.

Run some RF into the tuner.  Hold the glass part of the bulb in your 
fingers and touch the base to the output to get a feel for what's going on.
