Re: SX-110 History
¿ªÔÆÌåÓýThe first of the series was the S 20R.? The S 40 was nearly identical electrically but restyled.? Probably the largest change of electronic design was the S 40B.? From the time of the S 20R, about 1938,? there were more expensive models with an S meter, crystal filter, separate speaker, calibrated band spread and other features.? Hallicrafters always? offered good value for money but seldom world class performance.? ?They tried to offer something in each price range. Just about all of the ham manufacturers tried to offer something new when sets became available again after ww-2 but few sets really were new.? For instance the HRO 50 was really much the same as earlier HROs but on a single chassis.? The Collins 75A1 was really the ground breaker but Hallicrafters got on the bandwagon pretty quickly with reasonably priced double-conversion receivers . ?The decade after the war was one of extreme competition especially with the entry of new companies in the market.? A look at the advertising of the period is enlightening. -------- Original message -------- From: Michael OBrien <k0myw@...> Date: 10/12/22 8:59 PM (GMT-08:00) Subject: Re: [HallicraftersRadios] SX-110 History The S-40 begat the S-85 which begat the S-108. Add an S-meter and crystal filter, and the S-85 became the SX-99 while the S-108 became the SX-110... Bill Halligan was a master marketer. He refreshed and revised the outward appearance of his receivers every few years without major upgrades in internal circuitry, much as automobile manufacturers used to do with new models.

Yes, the late 50's and early-mid 60's was what I would consider the 'golden age' of communications receiver manufacturing. The transistor had been invented in the mid-50's and was quickly being developed for use in consumer electronics, including SW and communications electronics. Just like in the automobile industry where you had the "Big 3" manufacturers (GM/Ford/Chrysler) competing with each other, coming out with new models every year or so, so you had the "Big 3" US receiver manufacturers competing for customers - Hallicrafters/ Hammarlund/ National. They tried to appeal to a wide group of consumers - casual SW listeners, experienced SWL's and hams. So you had the entry level SW radios like the S-120, then the more sophisticated comm receivers like the S-108, SX-110, SX-122, and the ham band only receivers designed exclusively for hams (SX-117, SX-115). It must have been a bee hive of activity at the old Hallicrafters factory in Chicago, with rows of ladies assembling and hard wiring/soldering all the various receiver models they were turning out. Things evidently starting going down hill in the late 60s - early 70's when the Asian manufacturers started competing, selling all solid-state receivers that were smaller, lighter, drift-free and often cheaper. Eventually all the US receiver manufacturers couldn't compete and went out of business in the 70's. A sad end to a long line of wonderful US-made communications receivers that were so well designed and? made and easily restored after 50 plus years that we still have many of them being used and enjoyed today.? ?
