[Hallicrafters] SX88 Dial belts

[Greg Gore]

I can answer your question. Jim Jorgensen; K9RJ (now SK) had a small production run of SX-88 bandswitch belts (around 100) made from the original molds about 20 years ago or so in conjunction with a friend who was also an engineer at the Dayco Belt Company in Dayton, Ohio. Jim was selling these repro belts quite regularly on-line and at the Dayton Hamvention for about $25 each I think it was and managed to sell most all of them over the years but had held back a few. I spoke with Jim about his belt project many years ago at a Dayton Hamvention and he said with less than 100 known surviving SX-88s that 100 belts seemed to be a reasonable number to reproduce. About 10 years ago or so I learned Jim may have sold the small remaining lot to another hobbyist who reportedly was Chuck Groome; K5CEG of Paris, TX. It was also reported around that time that Chuck Groome was getting $500 for "new" SX-88 belts. K9RJ reproduction belts do occasionally appear on eBay and I was fortunate to get another one there about ten years ago for around $130. If you're interested in pursuing a reproduction belt or looking for something which might be a suitable substitute I just measured an original SX-88 bandswitch belt. It is possible the length has changed slightly over the years because the tooth pitch is not an even number. Carefully measuring along the outside surface of the belt I get 27.5" The belt width is 1/8" (.125) and the tooth count is 112. It looks like roughly 4 teeth per inch.
