Rare Hitachi KW-WSI WorldSpace Receiver on Ebay

This is the first and only “WorldSpace” satellite receiver I’ve seen on Ebay, currently offered at a $175 Buy-It-Now price from a seller in Australia:

http://www.ebay.com/itm/HITACHI-KW-WSI-DIGITAL-RECEIVER-WS-FM-MW-SW1-SW2-/282192383263

The radio is listed as in excellent condition with the original box and literature. Besides the long-gone WorldSpace satellite frequencies, the radio covers medium wave, FM, and most of the shortwave range. A brief PDF data sheet for the radio gives a description of features and operations.

hitachi-kw-wsi

Wikipedia describes this radio’s satellite service as 1worldspace, formerly known as ‘WorldSpace’, is a defunct satellite radio network that in its heyday provided service to over 170,000 subscribers in eastern and southern Africa, the Middle East, and much of Asia with 96% coming from India. It was profitable in India, with 450,000 subscribers.

I wonder if the Hitachi KW-WSI is a reasonable performer for shortwave listening? Does anyone know any technical details of this receiver?

Vintage Unboxing: New-in-the-Box Magnavox D2935 Receiver from 1987

D2935 1000pxSometimes good fortune drops in our lap at the least expected moment, but we have to act quickly to take advantage of it! This was the case with the receiver above; I spotted it on Ebay just moments after the seller posted a Buy-It-Now auction. Had I been planning to buy a D2935? No, but I immediately knew I was looking at something special.

This particular D2935 receiver from Magnavox had remained new and unused from 1987 until July 2016, when I had the good fortune of spotting the newly-listed Ebay auction and purchasing the radio for $175.    Continue reading

Radio Botswana, 1987 Style

No seasoned shortwave DXer can forget one of the most distinctive interval signals ever–the “barnyard animals” which marked the beginning of the broadcast day of Radio Botswana, Gaborone, for decades.

On its long-time frequency of 4820 kHz, Botswana was an occasional catch for me from the Seattle USA area. I yearned for clearer, more reliable reception of this station and other Africans which my East Coast USA DXer pals enjoyed!

It was always fun–and a DXing challenge–to catch Radio Botswana’s interval signal and sign-on announcements, but it was typically mid winter for reception in Seattle. Propagation on 60 meters needed to be favorable to enjoy anything other than a weak, barely listenable signal. Imagine my surprise and excitement when on the evening of December 27, 1987 I came upon the following signal booming in on 4820 kHz, far, FAR better than any previous Botswana reception. Indeed, their signal that evening surpassed in clarity even the Papua New Guinea and Indonesian “regulars” I would hear on the tropical bands from the Northwest USA.


This recording begins with the famous barnyard animals interval, the beautiful Botswana national anthem (Fatshe leno la rona, or This is Our Land in English) and is followed by a full list of broadcasting frequencies and times in English and the (presumed) Setswana language. That information is followed by a flute instrumental version of the Christian hymn Beautiful Savior, which introduces a short devotional or scripture message. The 10 minute recording wraps up with an a cappella children’s choir.

My receiving setup for this 1987 recording was an ICOM IC-R70 and a 300 foot long random wire antenna. Such a long antenna is unusual for the middle of an urban area, but I took advantage of living in a 3rd floor apartment across from a small city park. One midweek day, while most folks were at work, I managed to string out this long antenna with very small diameter braided steel wire from the 3rd floor apartment balcony to a distant treetop. This “sloper” antenna had significant directivity to the northeast, which happens to be the bearing for many African stations heard from the Pacific Northwest USA. The small diameter wire was suspended so high that it was virtually invisible from ground level.

My ICOM IC-R70 receiver handled the strong signals from nearby MW & FM broadcasters surprisingly well with the addition of a Grove Tun3 Mini-tuner preselector.

I continued to log Radio Botswana occasionally on 60 meters until the station eventually left the air (early 2000s I think), but I never heard them again with such a strong, clear signal as in late December 1987!

Very Scarce Kneisner + Doering KWZ-30 DSP Receiver Surfaces on Ebay

Hailing from Germany, the KWZ-30 communications receiver was one of the first DSP receivers available. This collectable and high performance receiver is rarely seen for sale, but one is now available for a $1890.00 Buy-It-Now price from a Russian Ebay seller. Even with the few dings visible on the radio’s case, it’s likely worth the asking price to a collector.

KWZ-30

The extensive Fenu-Radio web site has a nice capsule review of the KWZ-30, including some excellent photos.

At the $1890.00 price of this KWZ-30, you could buy a dozen SDRPlay receivers, or roughly a couple of the highly rated Perseus SDRs. Assuming available funds, is the KWZ-30 a receiver you would add to your radio shack? If so, why… or why not?

Psst, Buddy! Wanna Buy a Spy Radio?

This unusual Ebay posting is one of the most interesting I’ve seen in a long time: a genuine, new spy radio transceiver!

Given its rarity and new condition, the $1,900 asking price seems reasonable to me for what a well-heeled collector might pay. The set is referred to as a “FIELD SET MODEL FS-5000 SHORT WAVE SPY RADIO”.

It comes as one carton containing four larger fiber boxes and three smaller fiber boxes, all containing modules that are combined to make a digital radio transceiver system.

The seller says that the equipment (complete with shock-absorbing transit containers) bears no manufacturer marks, but was likely made in Germany by Telefunken. The various components look to be extremely well made, and the seller has provided these links for more information on this unusual 0.5-30 MHz transceiver:

What Would YOU Pay for a New, Sealed Box Sony ICF-2010?

Every radio enthusiast knows that the Sony ICF-2010/2001D was a desirable, high performing portable receiver throughout its long production history. Manufactured from 1985 through 2003, few receivers were as consistently high on DXers’ “must have” list as the ICF-2010.sony2010

These Sony portables still command high prices on the used market, but what would you pay for a brand new, still in the sealed factory carton ICF-2010? Well, someone just won the high bid on this new, unopened 2010 for the princely sum of $982.00 USD plus shipping:

1.8MHz 9th Order High Pass Filter Kit

hpf9-1m8a-500x500In reply to our post about a home brew high-pass filter, SWLing Post contributor Guy Atkins replied:

I recently purchased one of these high pass kits and an enclosure from an Australian company, and look forward to assembling it:  http://www.minikits.com.au/electronic-kits/filter-kits/hf-highpass-filters/HPF9-1M8

The price was just $14.95 USD at the current exchange rate, but I did pay extra for the matching enclosure.

It’s a 9th order Chebyshev filter at 1.8 MHz with less than 1 dB insertion loss from 1.8 to 100 MHz, and I expect it to work very well. Since it’s a kit with all parts and a PCB, it is half way between a “DIY from scratch” and a completely built commercial high pass filter.

Very cool, Guy! Looks like it’ll be a fun kit to build. Please let us know what you think of the filter once you have it assembled. $14.95 is a very fair price.
