Mar 4, 2012 · The SX-28 is undoubtedly Hallicrafters’ finest pre-World War II radio (excluding Hallicrafter’s special dual diversity DD-1). This radio came from the era in which the “boatanchor” moniker was born. The SX-28 is a well engineered and heavy single conversion broadcast and HF receiver offering coverage from .55 to 42 MHz in 6 bands.
The SX-28 is a well designed receiver. It has a wide selectivity range, an effective noise limiter, and a beefy broad warm sounding output. It was hi-fi for the period. However, if you're not handy with the soldering iron, stay away from this beast. The quality of parts used is very poor.
Hallicrafters advertised in early 1946 that they had built 50,000 SX-28 and SX-28A receivers but this seems to be exaggerated advertising hyperbole. Based on reported serial numbers, the estimated production is about 17,000 SX-28 receivers and about 11,000 SX-28A receivers for a total of 28,000 receivers.

One of the most beloved of all communications radios, Hallicrafters' Model SX-28, dubbed the Super Skyrider, was sold from 1941-1944 and was their top-line receiver. Many thousands were manufactured for government service during World War II, so this radio has historical significance and is also fairly plentiful. This article contains a detailed ac...
Model SX-28 was Hallicrafters' finest receiver during the years 1940-1944. It originally sold for $159.50. During the wartime years, Hallicrafters introduced Model SX-28A, essentially the same receiver with minor modifications in the RF section. By 1944, the SX-28A sold for $223. This Hallicrafters ad from 1944 shows the SX-28 and tellspeople that ...
The following photo shows my SX-28 on the day of purchase. To the right of the chassis are its empty cabinet and a matching PM-23 speaker that I had bought the previous year. The next photo shows the top of the chassis. The seller of my SX-28 had owned it for 31 years and used it much of that time. The set was well cared for, but showed an average ...
The SX-28 is a difficult radio to restore. Its electronics are cramped and there are many small components to replace and check. Aligning the receiver is a complex, highly exacting process. If you are novice repairman, it's better to cut your teeth on a simpler set such as a Hallicrafters S-38 or S-20R,or even a five-tube "All-American Five" tablet...
With the electronics in good working trim, it was time to turn to cosmetics. The front panel looked like it had been stripped to bare metal and covered with dark varnish. The only cure there would be to repaint it in the original color and restore the white and red lettering using lacquer sticks. Since the lettering, pinstripes, and leather-like te...
At long last, I was ready to put the SX-28 back together. During the panel phase of the project, I had carefully cleaned all of the knobs, using a warm-water soak to remove the orange shellac that had been sprayed on them. Note that the numbers and markings on the knobsare painted on. Don't scrub them too hard, or you'll removethe markings. Digging...
The final photos show the completed receiver in action, with its matching PM-23 speaker. To be honest, I don't like the color of the cabinet at all. It's a sort of greasy greenish light gray, not a good match for the panel color at all (or for the PM-23 speaker cabinet, for that matter). If I knew I was going to keep this set for the rest of my lif...

Apr 17, 1998 · The inductors in the SX-28 are mounted directly to the main chassis and are adjusted using the protruding screws. Whereas, in the SX-28A, the inductors and capacitors for each section are mounted on boards to form modular units. The inductors are tuned by directly accessing the notched tuning slugs. I have the manuals to both the SX-28 and SX-28A.
