    I recently saw a photo of a console at the FCC 
monitoring station at Grand Island Neb.  It featured several 
S-27 or possibly S-36 receivers along with a couple of 
Super-Pros. I can't find it and am not sure if it was on the 
web or in an ancient QST I was reading in the can.  While 
searching around the web for it I found:

Hallicrafters sold a commercial receiver about like this 
following the war as the S-37 covering 130 to 210 Mhz. I 
also discovered that there were two versions of the S-27, 
the S-27A covering 27.8 to 143 Mhz and the S-27B from 36 to 
165 Mhz.  The S-27C shown in the web site above looks more 
like the S-37.
    BTW, I have an S-36, former U.S.Navy, which I am in the 
processes of repairing at the moment. In addition to the 
standard model the military also had a modified version with 
an additional RF stage to prevent radiation of the LO.  I 
don't remember the model number but I think there is a 
handbook for it at BAMA.
     Hallicrafters sure was a funny company, in some ways 
they were right at the cutting edge and in other ways didn't 
quite make it.
