[Milsurplus] BC-375/ARC-2/ART-13

[Hubert Miller]

I have 2 of them. I do not know if i will keep any! I like the looks and the good frequency calibration.
Years ago, in Seattle, a burglar took an ARC-2. I still don't get that and wonder how it ended up. This would be around 1985, and was one of the ones sold by Fair for $50. It occurs to me now, this may be one of those surplus items whose value is "flat". I also about the same talked with a guy who had used one in his car on a camping trip. Yes, believe it or not. I don't recall how he got the 24 volts, and yes, he said when receiving CW you had to retune off the operating freq, and yes he said you could do it, which sounded kind of not so practical. Made me think of the Forest Service model S radio, a vhf superregen with no rec - trans equaization, so that a QSO gradually crawled across the band.
Roy Paffenberg's selectivity solution in his conversion booklet, using a regenerative IF stage, is not for me, as i tried it with Command Receiver and i was not at all happy with its functioning - as we discussed here, some time back. I have an early SSB era book that shows a Franklin osc using 2 6C4 with 2 caps of 1 pF attached to the LC. A 2 terminal oscillator. 'Amateur Radio Techniques' by Pat Hawker ( RSGB book ) has a 2 terminal regen amp, no LC of its own, which you connect across an IF can LC. So i was thinking this SSB book circuit with approx 1 pF load could do the same and not create major tracking problems. I think you build likecin the Hawker book the works right into the radio and the DC control pot is elsewhere you choose. I do not like the external Q5er idea, the external MF receiver; that's too Mickeymouse for my taste. Who knows if i wii actually try this though. I need to radically decrease the number of projects. Oh, last note, i would not use 6C4 or any other tube. I would use 2 MOSFETS.
