Image is of the R 390A overhaul line at new shop space at Stow's Minuteman Airport. Other pictures show a couple of interesting variants, one having a black CIA style panel, and the other with the polished aluminum VIP style panel. The ferrite is an improved antenna feed adapter which unlocks the legendary performance of this receiver.

Other images show an assortment of magnetic loop antennas adapted to my recent restricted space, high noise QTHs. The hexagonal  loop tunes 160 thru  80 meters, made from 3" tubing and can be mast mounted or hung from a tree. The copper tubing loop tunes 60 thru 15 meters.  Stealthy magnetic loops are effective in an urban environment with exterme noise and tight space.  The double loop can also enable duplex (repeater style) HF operations as the high Q loop design has much the same effect as the tuned cavity used at VHF. Technical details, http://bulldogtrust.com

Not shown is the full wave 75 meter wire "martini glass" or "lazy delta"  wire loop at the new QTH at 302 Boxboro Rd, Stow.  This antenna covers 10 - 600 meters.   Fed against ground with 40 Watts into a loading coil of 180 uH, it is used for experimental 600 meter station WG2XSB at 482 Kc nightly.   From 75 meters on down to 10 it is fed as a loop with a Murch tuner and a Collins 30L1.
