eBay Find: Sangean ATS-818 shortwave portable

While browsing eBay a few moments ago, I noticed this Sangean ATS-818 which has a BuyItNow price of $30.00 + $15.00 shipping. If this would have been the ATS-803A/DX-440, I would have snatched it up in an instant if only for nostalgic reasons. I know many people that cut their teeth on the ATS-818 or the RadioShack equivalent. The price seems fair, the unit is supposedly functional and the seller has stellar ratings.

If you’ve been looking for an ARTS-818, this might be a good time to pull the trigger.

eBay find: Sony ICF-SW100S

Many thanks to SWLing Post contributor, Rick Lewis (WPE5BST), who writes:

Have been watching this radio on eBay. […] Looks like a post 97′ model SW100S and thus the ribbon cable shouldn’t be an issue.

It appears the seller may only be willing to ship this within Europe. You would need to ask about international shipping prior to bidding.

I love my Sony SW100–it’s one of my go-to travel portables! I’m still most grateful to my buddy, Vlado, who fixed the ribbon cable in my unit. Click here to read more.

As Rick mentions, this Sony SW100S shouldn’t have a ribbon cable problem like the original SW100 series.

Possible record auction price for a Panasonic RF-8000

Many thanks to SWLing Post contributor, Dan Robinson, who discovered this excellent condition Panasonic RF-8000 which recently sold on eBay for $5,100 US:

Dan believes this is possibly a record price for this receiver. I would tend to agree. It does look like a beautiful receiver.

Any SWLing Post readers own a Panasonif RF-8000? What do you think of it?

eBay find: Zenith Transoceanic in an Unopened Box

Many thanks to SWLing Post contributor, Robert Gulley, who shares this link to an eBay auction for a Zenith Transoceanic D7000Y in an unopened box!

Let’s be clear here: this is no “Black Friday” deal. The seller has this gem listed at $5,800 plus shipping! I think this is the first time I’ve ever seen a Transoceanic listed at this price level.

Of course, as one friend always reminds me: “eBay is there to show you things you’d rarely stumble upon in daily life–you just need a chunk of change to snag it!”

The seller is listing this as-is since he isn’t going to open the box to test the unit. He does claim that if it arrives DOA, he’ll have is repaired free of charge (buyer pays shipping).

Still: $5,800 is hefty sum–several thousand over my threshold! No doubt, a Transoceanic collector will snag this eventually.

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.
