Paul, to get these to work, you will need  the loop antenna.  This has, 
in the early versions at least, a  Nuvistor amplifier in it with a 
crystal filter built in to it.  I  think there was a later version that 
had transistors.  I have seen  the schematic somewhere, have you tried 
TvB's site?

Hi Dan and Paul
 
The ops and service manual is available from the Agilent site........
 
_http://cp.literature.agilent.com/litweb/pdf/00117-9029.pdf_ 
(http://cp.literature.agilent.com/litweb/pdf/00117-9029.pdf) 
 
Although not the best pdf manual ever it does contain the schematics,  
including both antennas, and should be usable.
