Hello, Would anyone have Info, heard of or even seen this interesting receiver made by DEVELCO Inc. labeled , Research Receiver System Mod 101298 or 101484? I now have both models of this completely modular unit from the early 70's. Modules are: Preselector covering 2-30 Mhz in 4 bands with ant tuning, HF tuner using two thumbwheel selectors, Synthesizer using 4-5 thumbwheels, a first If with two bandwidths, 2nd IF with agc controls and lastly a "Coherent" detector section with at least 4 bandwidths. There are 3 mixer/converters on the rear apron that are connected via BNC and small UHF connectors and two outputs of the detector. There are no meters. The second unit appears to be a VHF rec. setup the same way. I don't have that in my shop just yet tho. So far most of this is working altho alignment is needed. I can provide Pix and more info later. Thanks, Wm. Courtright KB3DKS
