[Boatanchors] Globe KIng Panel Meters

[w5jo at brightok.net]

The iron vane had a shaft with a pointer attached and supported by bearings. 
One piece of Iron was on the shaft and another fixed below it.  I recall 
taking one apart  to see how it worked,. back in the mid 50s.  The Heath 
AT-1, DX-20 and 35 had them and as I remember they were Iron Van movements. 
I believe Heath switched to the Taut Band type in the DX 40 and up.

I am not referring to the Power output of the Globe King, only the type of 
meters it used.  I am sure they were chosen based on the normal thing, 
engineering specifications as modified by accounting.  Leo did have custom 
scales made with the company name on them.

Jim,

What did the iron vane meter use for an axle to support the vane?
If he used the least expensive they were Taut band meters --- bouncier than
a pogo stick.  They used a twisted wire to support and calibrate the
armature.

But the meters were common off the shelf, Leo would use the least expensive
parts available.  I doubt he would pay to have others made.  Simpson and
Triplett all developed and sold that kind of meter.  The only other thing
one could get for a reasonable price was the iron vane type common on the
little Heath, Knight and other Novice transmitters.

But the GK500 was 500 watts input or somewhere in that vicinity.
