[Milsurplus] Surprise at Shreveport Hamfest 2025

[Hubert Miller]

I have that many BC-348 also. Actually from BC-224-A to R-849 with the squelch box on top. One could actually go overboard and collect BC-348 variants; the good thing us, the list is not endless: it's hard limited to about < 20, with the postwar German rebuilds and the airline labeled ones.  But, time is also hard - limited.
I think i will only keep one or two, probly the early versions with no LF band, maybe the one with the factory - looking AC supply. But i sure don't want any uncommon versions to go overseas, not on my watch, anyway. I still rue that this "first Army superhet receiver ( BC-189 ?? ) went to Italy a couple score years ago. I should have bid just to prevent that, even tho i have no interest in that item really. ( I gave a "restorable" one  away a few years back. The recipient is not a "communicator" and God only knows if he will actually summon the togetherness to actually restore it, but what's done is done....)

Back to BC-348: One thing i just have to try: that's the selectivity mod where you run a shorted turn of wire between IF can primary and secondary. This kink wasn't seen first in CQ mag; i found it also in  Radio Craft mag from the late 1930s. I also wonder about changing the last IF can from overcoupled secondary to same inductance as other windings. But i would need to take a closer look at the diode load Z. These are non-apparent non - obvious minor mods. I also wonder abt solidstating them, i mean via a direct plug-in replacement, not modifying the wiring at all. Maybe. I hate having to stock a whole variety of tube families. Some things are uncommon enough tho that you don't even want to do this. Maybe.
