Don, ?It would seem Hallicrafters was slow in adopting solid state design for their higher end communications receivers, up to and including the SX-133 radio. They did, as you pointed out, make a SS

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,

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

When I was in grade school someone from NASA visited our school and told us about transistors. They needed something small on the space crafts to save weight and space on the crafts. This was in the

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

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

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

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.

Walt, About a year ago, I stumbled across a “CB” site that sold me some multi-conductor coiled cords… I’ll see if I can find the name, but think they’re still out there. Tom – W?EAJ PS

Negative Steve kw4h. I have the *SX-110, Mark1A* Not SX-101 The SX-110 Mark1A manual is not available on BAMA The *Mark 1A* is stamped on the chassis, it has the same tube lineup, but some circuits,

The 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

Sounds like this is a conduction cooled pin to help over all cooling at the bottom of the tube. -- 73/Rick WA6III __________________________________ No critters were injured transmitting with

The SX101 is an absolutely beautiful receiver! My SX101 Mk III? will be right next to my SX115 and will be used with an EF Johnson Viking Valiant on 160, 75 & 40! Pictures to follow! -- 73/Rick

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

Steve, ?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

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.

I also agree. Absolutely love my SX101A.

Walt, Thanks for the reply. Will this simulate the key line being plugged into the 2-NT? If I use this key line to supply the 12 vdc for the T/R relay will that work? I am currently using an external
