hallicrafters sx-28
I've always wanted one of these. But it looks like it was sitting in someone's barn for decades, and I'm going to have to completely strip and repaint the cabinet (the sides are way worse than the front), but it's complete except for those 2 knobs. I have too many other things apart I'm working on now, so it'll probably be months before I get to this.
But I was wondering if anyone knew what that symbol stamped on the front referred to. It's a big 'A' inside a square. To the left of the 'A' is an 'S', to the right a 'C'. Inside the top part of the 'A' is an 'L', inside the bottom part is 'M01'. Last edited by Adam; 08-21-2015 at 02:54 AM.

Most likely a military Depot stamp - all the Navy and Army Depots have one. The L and C are most likely Logistics Command or some other variation. Sacramento Air Logistics Center is one possibility. They did tons of electronics work there.
Lockheed Aircraft had a stamp like that too, as did good ol' Grumman. LAC and GAC, respectively with the squarish perimeter and the center "A" was always larger. Somewhere I've got a MILSTRIP guide that has all the depots listed. I'll look and see if I can find it. Cheers,

Boatanchor? More like a supertanker anchor!! Have fun with your Halli!! A friend's Dad had one when I was a kid...we spent many hours cruising the SW bands with it. From what I understand, tread lightly in the RF section...a difficult part of an SX-28 to work on. I'd love to stumble across one at a garage sale for $10 or so. Hey...a guy can dream, right?
BTW...pop an ad in the classifieds on www.qth.com. You might come up w/ the missing knobs.

I had a Triumph Oscilliscope(labeled Oscilligraph on the case) that was accepted by the US Navy in 1944. There was a metal tag on the top indicating this.
I gave it to the Texas Parks and Wildlife dept. for use in the USS Texas battleship radio room restoration. It was in much better cosmetic condition than the above radio.

Interesting, I know they made that heavy duty AN/GRR-2 version during the war, but this is just the regular old SX-28.
I looked up sacramento air logistics center, and they do use the acronym SMALC, which would account for all the letters in the square, but I couldn't find an image of that particular stamp anywhere. The other numbers stamped on the front: [XX]-5-11 48, I had assumed were a date, but that doesn't explain what the 2 numbers (or letters) mostly rubbed off before the '5' would be. This is a heavy unit, I'd guess about 80lbs.

When you're ready to tackle it, these restoration notes may be useful.
http://antiqueradio.org/halli12.htm Re-doing the RF deck is tedious, but not rocket science. Tag things and take photos as you go. Have fun! It's a great piece of history. You should enjoy it when you're done. Phil Nelson Phil's Old Radios http://antiqueradio.org/index.html
