[Milsurplus] Harvey Wells AR-5A Military Aircraft

[D C Macdonald]

My guess would be that the TOWER setting gave
you full audio (.3 - 3 kHz) and the RANGE setting
was a filter (bandpass) centered on 1020 Hz.

I recently got a Harvey Wells AR-5A military aircraft radio.  It has two 
bands, 200 to 400 Kcps and 550 to 1650 Kcps both AM detection.

There is a switch on the front with a position for Tower and one for Range 
and others.  I know that the Range was in the VLF frequency band, but did 
the tower in the late 40s and early 50s use VLF??

This set is extremely clean and is complete with an attached AC power 
supply.  I have not yet tried it out but am thinking of using it for the 
final IF of an AM converter (yet to be built) for 80-40-20-10 where the 
output of the converter will be 200 Kcps chunks of the various ham bands.

I have also heard that there is conversion information for this receiver 
that details the conversion of the receiver to the ham bands without using a 
converter.

Does anyone have any information on this receiver or on the conversion of 
this receiver to ham bands.
