SX-110 History
My father gave my mother a birthday gift in 1957 of the Crosley "book" radio - one of the early consumer transistorized radios, that hit the market in 1954: It was actually a hybrid with 3 sub-minature tubes and 2 transistors. Required a big B (45V)? battery and several A batteries:

SX-110 History
Don - you are correct. First transistor was invented by Shockley, et all at Bell Labs, NJ,? in 1947. My intention was to convey that the dissemination/utlization of transistors? into consumer products (eg. comm. receivers) did not really occur significantly until the mid-late 50's. Hallicrafters and the other major US receiver manufactuers? were still relying primarily on hollow state design but eventually began developing solid state circuits for use in their receivers starting around this time, into the 60s/70s..?

Re: SX-110 History
开云体育Bob? ,,,and group I am caching up on my inbasket and had a look-only at previous comments I had no intention of sticking my nose ?into these ?interesting ?comments on “the SX-110 History” ?including ?ford vs. chevy, but then I ran into? ?“transistor had been invented in the mid-50's”… That is news to me. I doubt that Bardeen, Bratain, and Shockley would have agreed on that. Bardeen, and Bratain demonstrated transistor action on Christmas eve 1947? seems to be well documented, and official invention patents ?etc were not far after. ?By 1953 Raytheon was releasing the ck721 and 722 for a few bucks to experimenters …like me. And in 1954 the regency TR-1 was available. ? Sorry ?for intruding on this point, as it is not really “on? topic”, but ?this additional? comment ?regarding when the transistor was invented does not seem to be supported, by available resources, or my old books. ??

Re: old mic
开云体育Amazon has several multi conductor microphone cables. Some are described as "CB" items and others are listed as being replacements for specific amateur radio transceivers. Maybe one of those would work?

The HA-2 is getting rare. The ground to ground function was 30 to 40 MHz. The Air to ground function was 115 to 135 MHz. If it doesn't have the ground to ground/air to ground switch it is an HT1E.
Hope you can find the mic cable source info.

Re: SX-110 History
开云体育Bob, ? Thanks!? Looked that one up.? So -- it’s interesting that in between the SX-99 and SX-110, Hallicrafters produced the S-108, which appears to be the S-110 without the crystal filter and S-meter.? Both appear to have been somewhat midrange in performance.? I’m trying to discern what Hallicrafters was doing and why, but it may be impossible to figure out – kind of like why Sony would have produced a stereo system in 1972 that included an auxiliary input, and another one that didn’t a couple of years later. ? 73 – Steve, KW4H ? From: <[email protected]> on behalf of "Robert Needleman via groups.io" <k3ac@...> ? Nope- they started making the S-108 in 1959 (big year for me- I started 1st grade)! Bob K3AC
