What made the Squires Sanders SS-1R receiver legendary?

ss-1r

Many thanks to SWLing Post contributor, Michael Black, who reminds us why the Squires Sanders SS-1R receiver (Dan recently spotted on eBay) was so innovative at the time:

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

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

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.

But the second IF  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.

It does seem a relatively simple design now, but wasn’t fifty years ago.

The ham band version was the “big seller”, the shortwave version maybe offered because they could.  It’s not clear if the front end needed changes to cover the SW broadcast bands.  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).  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.  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”.

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.

eBay Find: Rare Squires Sanders SS-1R receiver

ss-1rMany thanks to SWLing Post contributor, Dan Robinson, who shares this recent find on eBay and notes:

Extremely rare Squires Sanders on Ebay….amateur receiver….only the second time in recent years one of these radios has come up on the used market…

I was not at all familiar with this ham band receiver, Dan.  I like the unique analog two digit log/frequency display below the main dial. Looks to be pretty clean, though the seller notes that this is an estate item and has not been tested. A buyer would have to assume the cord and, most likely, a few capacitors will have to be replaced.

ABC International to increase investment in services for Chinese, Indonesian and Pacific audiences

ABC Australia

Many thanks to SWLing Post contributor, Richard Cuff, who shares this press release from ABC International:

ABC International focuses investment in region

ABC International will increase its investment in media services for Chinese, Indonesian and Pacific audiences to offer more comprehensive coverage for regional audiences. These new initiatives, the result of a strategic review, mean ABC International will be better positioned to deliver a greater range of content in these areas.

The changes mean ABC International will create eight new positions to lead content areas and improve editorial and workflow priorities. However, ABC International has also made the decision to end foreign language services in French, Khmer, Vietnamese and Burmese, which are currently single-person operations.

The recommendations from the strategic review and the decision to close some services will fund this reinvestment across the network. ABC International will build on key relationships with China, Indonesia and the Pacific with increased investment in services including:

  • For Chinese audiences: an additional Mandarin language site allowing ABC International to deliver a full Chinese news service, for Chinese audiences across the region and Australia, complementing the AustraliaPlus .cn cultural exchange portal.
  • For Bahasa Indonesian audiences: two new roles will be created, a new Content Maker and a Senior Producer, to improve ABC International’s capacity to extend Indonesian language content.
  • For Pacific audiences: the creation of a new Senior Producer Pacific position focussed on enhancing content for Pacific audiences. This new role will also manage and schedule the Radio Australia Services and the Pacific and Tok-Pisin service that has a distinct value in reaching PNG audiences.

Two other new Content Maker roles will be created, one with a focus on telling Pacific stories to audiences in that region and a second position to tailor English content on Australian life for all platforms.

ABC International Chief Executive Officer Lynley Marshall said the changes to these services would benefit the wider audience base in the region.

“These changes are the result of careful consideration and commitment to our services in the region as we approach 2020,” she said.

“The ABC has a long history with the Pacific nations while Indonesian and Chinese audiences comprise a growing audience base, both across our region and here in Australia.

“ABC International is determined to uphold the highest standards in international media services including our expanding digital and social media services. These changes represent ABC International’s commitment to delivering compelling content to key audiences.”

The closure of the Vietnamese, Khmer and Burmese language services will become effective on 2 December 2016, while the French service will continue until arrangements with France Television end in February 2017. The closures will affect six positions and a staff consultation process will begin shortly.
