[Milsurplus] Harvey Wells AR-5A Military Aircraft

[WA5CAB at cs.com]

I don't have any info on the receiver (that I know of) but the answer to your 
other question is no, airfield control towers never used VLF, which is 
anything below 30 KC.  They could (and did) transmit voice at MF (300-3,000 KC) and 
in the upper portion of the LF band (30-300 KC) through their ND beacons.  And 
received and transmitted at HF (3,000-30,000 KC).  I've forgotten the exact 
reason for this although I can think of several plausible ones.
