\"ss-1r\"<\/p>\n

Many thanks to SWLing Post<\/em> contributor, Michael Black, who reminds us why the Squires Sanders SS-1R<\/strong> receiver (Dan recently spotted on eBay<\/a>) was so innovative at the time:<\/p>\n

It’s legendary because it leaped forward in receiver design, at least at the amateur level,\u00a0 and there was the article in QST\u00a0 in 1963 by Squires about the design.\u00a0 So lots of people knew about the design, even if they weren’t owners.<\/p>\n

There’s no RF\u00a0 amplifier, the antenna feeds the mixer trough a tuned circuit.\u00a0 There’s a q-multiplier on that tuned circuit, to improve selectivity (q-multipliers were mostly seen in 455KHz IFs).\u00a0 The mixer was a 7360 beam deflection tube, hard to overload, and a balanced mixer, which was likely a first in ham receivers.\u00a0 After, everyone was using 7360s for receiver mixers, at least until good solid state balanced mixers came along.<\/p>\n

I keep forgetting that it is still a dual conversion receiver (except for one band), though presumably to avoid other issues while allowing for a fixed 500KHz tuning range.<\/p>\n

But the second IF\u00a0 is at 1 or 2 MHz, higher than the usual 455KHz, a sign of the future, though there were already some SSB transceivers with IFs in the HF range.<\/p>\n

It does seem a relatively simple design now, but wasn’t fifty years ago.<\/p>\n

The ham band version was the “big seller”, the shortwave version maybe offered because they could.\u00a0 It’s not clear if the front end needed changes to cover the SW broadcast bands.\u00a0 But it would have been an expensive SW receiver, and needing another crystal for each 500KHz tuning segment, a new concept at the time (though a few years later Drake had their SW receivers like that).\u00a0 But that was the trade-off, most receivers did have a 2:1 tuning range, while some were like the R390 , very complicated mechanically and crystals for every band.\u00a0 A subset of 3 to 30MHz meant fewer crystals and a simpler bandswitch but you spent a lot of money for a receiver that wasn’t “general coverage”.<\/p>\n

Thank you, Michael, for the insight! At last glance, the bidding was only at $227.50. I suspect it will go much higher, but perhaps this will end up being a deal for someone.<\/p>\n
