Hi Thomas,

The new SSB portable receiver TECSUN S-8800 has been available from Germany, since the beginning of 2017.

Supplier:https://www.wellenjagd.com/ has the S-8800e, a Europeen version.

I have one unit here and also being an owner of the PL-880, [I would describe it as] a better PL-880 with more features.

DSP filters on SSB: 0.5 – 1.2 – 2.3 – 3.0 and 4.0 kHz

DSP Filters on AM: 2.3 – 3.0 – 4.0 and 6.0 kHz

Long telescoping Antenna L = 92 cm

BNC Antenna socket

AM External antenna (500 Ohm ) on panel….with an internal /external antenna switch.

Main and fine tuning [much] like the PL-880 , but all metallic buttons, bigger and of better quality.

VFO main tuning knob is large and has a good feeling.
Line out is stereo ( 2 channels ) L and R
Separate bass and treble control
2X LiH Batteries 18650 ( no external power supply possible, no 12V socket). Batteries can be charged while the rx st still in use.

On this S-8800e–my first impressions:

Very sensitive on longwave… ( PL-880 was not )

Very good copy of ssb stations

RX does not get so quickly overloaded as the PL-880 does…

Quite bigger than the PL-880 => 27 cm X 17 cm, about 7cm thick.

Wow–many thanks for sharing your first impressions, Bertrand!

I’ve been waiting quite a while for the S-8800 to be released. I will have one on order soon and will do some comparisons with the PL-880 and PL-660.

As you discover more about this receiver, please share your impressions with us!

Anyone else have the S-8800? Please comment!

Cold War radio treasure trove: The CIA Freedom of Information Act Reading room

Many thanks to SWLing Post contributor, Alexander (DL4NO), who writes:

I just found a German reference to the CIA Freedom of Information Act Reading room

https://www.cia.gov/library/readingroom/

As a first test I searched for “radio design”. A few of the documents found:

ACTIVITIES OF AMATEUR RADIO DESIGNERS

JPRS ID: 8744 TRANSLATION ELECTROMAGNETIC SHIELDING DESIGN FOR RADIO-ELECTRONIC EQUIPMENT

DOSO INSTRUCTION FOR AMATEUR RADIO OPERATORS; BULGARIAN RADIO EQUIPMENT PRODUCTION

AIRCRAFT RADIO COMMUNICATIONS IN THE USSR

This could be an amazing source, especially of historical information from the Eastern Block. But expect any search to be real work: Only the title and some classification of the documents are searchable. The rest is scanned documents.

Very cool–thanks for sharing, Alexander. I spent a little time this morning browsing the results using various radio-related search strings. It is a very deep archive.

Letter from former District Manager at Radio Australia Shepparton

2 Replies

Many thanks to SWLing Post contributor, London Shortwave, who shares the following letter by Gary Baker, former district manager at Radio Australia, Shepparton–published in the Shepparton News. Here’s an excerpt:

Recently I heard that the HF radio transmission site at Shepparton, known as Radio Australia, is to be shut down.

[…]I understand the ABC needs to cut back on some services it provides and make use of the latest technology. This makes sense except in the case of the Shepparton facility.The Shepparton transmission site has the capability to direct radio signals into specific countries as we see fit.

This is unique to this site, as no other site can reach the countries this one can.

In my time as district manager at the Shepparton site, I recall some instances where the Shepparton site was called upon to direct radio signals to specific targets.

At one point the Fiji Government shut down the local Australian ABC transmitter.

Shepparton sent radio into that country to keep Australians informed during that time.

When there was a coup in the Solomon Islands, once again we sent signals into that country.

We also sent radio signals into Myanmar at the request of the Australian Government.

Another task that the Shepparton site fulfils is to send signals into northern Australia in times of need, for example during Cyclone Larry when the Northern Territory radio service was beamed back to the tropical north from Shepparton.

The Shepparton site is in a location that has good weather and is politically stable.

This makes it an ideal tool for widespread information broadcasting.

The ABC would argue that this HF radio service is old technology and can be replaced by the internet or satellite services.

This is true.

However, the ABC and the Federal Government do not control the internet or satellite services in other countries and therefore they are not reliable.

HF radio broadcasting from a secure location is very reliable.[…]

The diminutive but brilliant Sony ICF-SW100: a few autumn/winter DX catches

10 Replies

Hi there, I posted an article on this brilliant little radio a few months ago because it had demonstrated a level of performance way beyond my expectations. Notwithstanding it’s incredibly small size the DX results I obtained with it were beyond my ICF-SW55 and up there with the iconic ICF-2001D. Armed with synchronous detection, selectable side bands, SSB, CW and sensitivity seemingly boyond it’s tiny form factor I can’t recommend this radio highly enough.

Originally introduced into the market in 1993 and discontinued in 2005, the ICF-SW100 won’t ever be repeated – a point I made in my original post, but of course they are available on eBay and prices remain robust for what is now essentially a vintage receiver. Unfortunately, I don’t get to use my ICF-SW100 very much as I have various other receivers and have been involved in antenna building/testing and MW DX for the past few months. However, on the couple of occasions when I have taken the Sony on a mini DXpedition, it’s resulted in some fine DX. As demonstrated in the examples below, Mali, Guinea, Alaska and Japan are amongst the more difficult signals to copy in Europe and yet the ICF-SW100 delivered them! Text links to reception videos on the Oxford Shortwave Log YouTube channel follow below and futher down you will find embedded videos. Thanks for reading/watching/listening and I wish you all great DX!

The past, present and future of UK pirate radio

Radio Caroline circa 1960’s.

Many thanks to SWLing Post contributor, Aaron Kuhn who shares this excellent article from Dazed:

The influence of pirate radio has endured despite government crackdowns and the rise of legitimate alternatives – today, it continues to thrive, both legally and otherwise

Drive around some parts of London today and you’re still liable to hear mainstream radio broadcasts drowned out by fleeting bursts of unfamiliar music. Pirate radio stations have been illegally hijacking the FM dial since the 1990s, but while the pirate scene is far smaller than it was in its heyday, the movement is still thriving on a local scale, while a vibrant array of online-only stations are inspired by the energy and spirit of the pirates. To put it simply, pirate radio never left London.

The UK’s pirate radio story starts with Ronan O’Rahilly’s Radio Caroline back in the 1960s, famously avoiding the authorities by broadcasting from international waters, but it was really the 1990s that paved the way for pirate radio in this country. Its evolution loosely follows that of the underground rave scene, which mainstream radio wouldn’t touch in its early days. “It’s the closest thing to mass organised zombie-dom,” BBC Radio 1 DJ Peter Powell said of acid house. “I really don’t think it should go any further.” Needless to say, it wasn’t going anywhere, and between 1988 and 89, pirate radio stations rapidly started to appear to serve a youth hungry for new sounds that weren’t being catered to by mainstream radio. By 1989, there were over 60 pirate radio stations operating in London alone.

While the first pirates – from Sunrise to Centreforce to Fantasy – mostly played music from America and European countries like Belgium, it didn’t take long for the British youth to start doing their own thing. “The UK kids realised people were making music in their bedrooms and they thought ‘I can fucking do that!’” exclaims Uncle Dugs, one of the UK’s leading authorities on pirate radio. Having been involved in radio (both legal and otherwise) for over 20 years, Dugs’ new book Rave Diaries and Tower Block Tales documents life as a young raver turned award-winning DJ after years on the pirate scene. As he explains, by 1991, London’s underground music landscape had become “99% UK producers and DJs,” transforming from acid house to hardcore and then to jungle. As London’s underground grew, so did its pirate presence, with legendary stations like Weekend Rush, Kool FM, Pulse FM, Innocence, and Defection springing up by the end of 1991. “You could flick through the radio and at every .2 on the dial there was a pirate station,” Dugs laughs. “There wasn’t even space on the radio for a new one.”[…]

How power outage “load shedding” is affecting Zambia ZNBC-1 and Voice of Hope

1 Reply

Many thanks to SWLing Post contributor, Richard Langley, who shares the following message he recently received from Ray Robinson, VP of Global Operations with The Voice of Hope. This message is being relayed with Robinson’s permission:

I have seen a few messages lately, regarding the non-appearance of ZNBC-1 on 5915 kHz in their early mornings. You may be aware of the rolling power outages called ‘load shedding’ the electricity utility in Zambia, ZESCO, continues to impose daily throughout the country. The outages are at different times in different areas, but at the Voice of Hope transmitter site, the outages have been effect from 6-10am local (0400-0800 UTC) since September. The ZNBC shortwave site is only a few miles from ours, and it would be logical they are on the same outage schedule. I know from when our staff visited their site a few months ago to buy some distilled water for our transmitter cooling systems before our own still was up and running, that ZNBC’s genset is not currently operational, and I don’t believe they have the budget either to repair it, or to buy diesel for it, if it was repaired and functional.

My guess is they have decided it is not really worth the effort to broadcast for the hour or so from 0245 UTC until whenever the power goes out. (This is just my speculation.) They do use 5915 later in the day after the much cheaper hydro power returns, but of course by then, the propagation conditions do not favor inter-continental reception.

As for Voice of Hope – Africa, we had expected the load shedding to end by December (two months into the Zambian rainy season), but alas the outages are continuing, with no sign of any change soon. Our own weekday morning broadcasts on 9680 and 11680 kHz have been entirely powered from our genset since September. This is expensive, and unsustainable. We have therefore decided to make a schedule change from next Monday. Instead of broadcasting weekday mornings from 0500-0800 UTC, we will switch to weekday evenings from 1700-2200 UTC, extending the duration of the broadcast from three hours to five. The last two hours will be ‘Night Light’ presented by Stephen Mdoma, reprising a program he used to present late nights years ago when the station was known as Christian Voice We will be using the frequencies 4965 kHz (omni) and 6065 kHz (to West Africa), which may also afford better opportunities for reception in ECNA after local dusk. The program schedule on our website will be updated this weekend. We plan to re-launch the morning broadcasts once the load shedding ends. I thought you might like to know.

Richard adds that Ray Robinson has also confirmed the weekend schedule is unaffected.
