The beauty I am referring to now, is the venerable frequency meter, model BC-221 or SCR-211 -- which you have seen at numerous swap meets or other places where cheap hams abide. Anyway, a long time ago, my dad had secured one and for several instances when I visited him, he sang its praises and regaled me in the tales of his restoration efforts -- down to the AC/DC power supply he fabricated.

Among the treasures, was this graceful old BC-221 (I cannot remember the make) that still did not resonate with me. To be sure, it was clean and functioning, I guess, but I had a signal generator and more than enough frequency counter, so what did I need with one of these, right? Sadly it was dealt off to someone somewhere. But for some reason, I kept his power supply.
Well, bored to tears and browsing eBay, I came upon an offering form a person in Orange, California for-a-brand-new-in-the-box TS 323 which was the Navy's version of this type of instrument designed for 20 Mc through 450 Mc. (It does not seem right to use modern day frequency in conjunction with these old fellas, so I won't.) Naturally, I could not let this slide so I forked over $120 and, since the guy was in Orange, it was a hop, skip, and a jump to hand him 6 double sawbucks and cart it home.

Sadly, I was on the slippery slope and it was only a matter of time before my friend in Orange had the lower range BC-221 (125 Kc though 20 Mc.) available. I think I got this for $50 or so and, while the inside was immaculate, I had to do some restoration on it. This, of course, was the BC-221-AK, manufactured by Philco for the military. The cabinet was wood and a little weather-beaten but the unit came with its original canvas flaps so the sprucing up consisted of washing and "oiling" the paint, removing the hardware and painting it either an olive drab workalike (the handle and the canvas retaining strips) or flat black (the latches). The bottom was a wreck, so I sanded it out and repainted it with the lighter shade of O.D. because it wouldn't show much. It came out beautifully as you can see from the pictures below.
..and, soon thereafter, I was visiting the monthly Chino Hills swap meet and, of course, stumbled upon an "-F" unit (BC-221-F made by Zenith) in a little poorer condition, but good nonetheless. I restored the outer aluminum case by sanding down a wretched, pitted wrinkle finish and painting it flat black. (Hey, you restore these your way, and I'll restore these my way.)
Inasmuch as I got tired of 'documentation snaps", this went straight to the bench to revive and calibrate. But the case came out pretty good and I'll get some pics up when I revisit the revival of this unit. But these are good enough for now.
To sum up this post, the BC-221s one finds, if one looks hard enough, can be treasures and diamonds in the rough if cared for properly. However, one stumbles on some quirks and electronic restoration problems occasionally. That's what the next couple of posts will be about.
See you then.
