Two BC-348's, some Hallicrafters S-somethings, and a Measurements Corp. signal generator.

Top one is a Hallicrafters S-21 Skyrider. It's been modified with a plug (for crystals?) in the upper left.
Next are two, what appear to be, BC-348's sitting on top of a signal generator.
Next one down looks to be a Hallicrafters S-22R Skyrider Marine.
The bottom one appears to be a Hallicrafters SX-24 Skyrider Defiant but I can't see if there is a another meter panel off to the right.

Larry.

I thought I'd get the prize for ID'ing the Measurements, but Geoff beat me!!

Should be a Measurements 65 HF signal generator. I always wanted one as a complement to my Measurements 80, but by the time I ran across one that was for sale I already had modern HP and Fluke digital display stuff. It dates from about 1949-59 give or take a year or two.

The BC-348's are a late J/N or Q model and then an earlier one, H/K/L/R/E/M/O/P/S etc.

Phil, I was referring to the Measurements signal generator on the bottom of the pile in second photo.

Oh-ok Peter. I'm the one who is a little confused I guess.

FWIW, I would grab the 3 Hallicrafters first, in this order; S-21 Skyrider (hardest to find), SX-24 Skyrider Defiant (best overall receiver of the bunch), and the S-22R Marine (low band + AM broadcast band). YMMV. :wink:

Is the S-22 marine the one with the crystal socket?

When I worked at a ham store about 40 years ago we had a display section of "old ham gear" and there was a Hallicrfaters S-something Marine that was a light seafoam green color, original paint. I have not seen another since.

The bottom Hallicrafters could be a SX-25 too. I've had a couple of them along the way and they are pretty good radios as long as the filter crystals were still close to correct frequency. But I agree that even in its present condition, the S-21 would be first on my list just because it is so seldom seen. The others are common by comparison. The BC-348 aircraft receivers tend to do pretty well online these days due to interest from military collectors.

The signal generator is a Measurements 65-B. About the best there was in HF signal generators from the end of WW-2 until 1958 when the HP 606A and General Radio 1001-A knocked it out of the ring. Even if you already have another signal generator, it is worth downloading and reading the Measurements 65-B instruction manual. It is loaded with practical advice and tips on making receiver measurements.

Once upon a time, I even owned a Measurements 65-B. It came from Polytronics. It still had the asset tag on it. It came from one of the former owners. They use it to test amateur radio equipment coming off the assembly line.

Wow, I got them all right! I oughta get a lollipop or something! :D

I like the Sky Buddy too, I picked a really nice one at Kutztown last year. That and my S-20R are my two favorite Hallicrafters. Nice haul!

I looked at this set a few weeks ago and wondered if the pilot and plugged hole on either side of the dial were original?

Phil,

How about some more pictures of the BC 348's.

Sorry but the bc-348's are still with the seller. I already have one so wasn't too interested.
