Re: Was SX-110 History, Now S-120
¿ªÔÆÌåÓý
Hmmm.? I got a S-120 for Christmas when I was about 12 (1963?).? I put up a 120 ft wire from the top of the house up to the peak of the barn.? Worked good.? Spent many nights listening to Clyde Clifford on?the "Beeker Street Theatre" radio program on KAAY in
Little Rock Arkansas.? Great memories.? I have several S-120 s in the bone pile.? It might be fun to use some JFET transistors to convert one from hollow state to solid state....? Another project for the queue.
Best Regards
Jim Zellmer,? ?KA0VSL

Bob thanks for your quick reply From my recollection , I generally agree with this ?comment, and all but the one small point in the previous comment. ?? As the topic has morphed a bit, it ?seems to me, Transistors were a great fad, and very good for portable BCB/AM use, but? were lacking for some time in power , frequency and audio ¡°fidelity¡±. So one would expect communication receivers to lag behind table radios in use of transistors. The transistor was not taken seriously by many of us for some time. ? As to a slightly different point, the S-120 was a tube receiver [presumably made in USA], but the S-120A version was all solid state, and made in Japan.. according to Dachis. I don¡¯t think I have a transistorized Halli ; I wonder if the ¡°chassis¡± on early transistor units ?was partly circuit board. ? Regarding some of the comments re the sx-101 styling, seems to me ¡°my¡± S-47 was the first slide rule dial used by Hallicrafters. When it comes to style ,the SX-115 seems very unique. So many aspects of these radios to think about. ??? Don VA3DRL ?

On Behalf Of Robert Needleman via groups.io ? 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..? ?
