[Milsurplus] ART-13

[Mike Hanz]

I guess I've never seen an ART-13B /without/ that switch.  I've had a 
half dozen here at one time or another with the CDA-T, all with the 
switch, and all with a nameplate to the right of the switch that sez 
"Low Frequency Extended Range."  It introduces a small cap into the 
doubler stage to allow for crystals down to 1.7MHz or so, IIRC.  Don't 
quote me - all my docs are down south now.  You can see mine at 
http://aafradio.org/flightdeck/b29.htm - about 1/4 way down the page 
there's a closeup of the two transmitters, the bottom one being an 
ART-13B (but without the CDA-T).

73,
Mike
