information.  The AT-1 meter had an annoying habit of banging around when
on CW but the schematic & parts list show the meter switch was 3-position,
with the unmarked center stop turning the meter off while still letting
the transmitter operate. My question is whether this feature was actually
mentioned in the manual or if it was overlooked.

   My manual shows five meter positions.
(I own two AT-1 Apaches, both junkers that I never used)
   (my DX-100, I used)

   final Icathode
   driv. Icathode
   final Igrid
   high  Volts
   Mod   Icathode

   I found no reference to an "off" position in the verbiage.
   I am guessing that you are looking at some other schematic than that 
of the Apache.
