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 version of the S-120 (S-120A) but this was actually made for them by a Japanese manufacturer (Trio?). The earliest, all SS communications receiver I know of is the Hammarlund HQ-215, which used Collins mechanical filters. It was very expensive and don't think it sold well as a result. I had one briefly, but wasn't too impressed with it compared to more modern receivers. Drake hung in there through the early 80's and made several all SS receivers (eg. R7, SW-4/8 line, etc) which were excellent albeit expensive. All the US comm. receiver manufacturers folded up their tents not long after that but it would have been interesting if they had hung in there and developed more all SS communications models. Sadly, we'll never know what could have been.
