Noordhoek DXpedition Ultralight Loggings : 11th - 15th January 2011

Noordhoek Beach - towards the south.

Noordhoek's ideal position on the Cape Peninsula provides a great opportunity for dxing mediumwave radio stations from across the Atlantic.

After the early evening reception from Africa and the Middle East, many stations from Brazil usually make it through to this location from late evening until our local sunrise with astonishing and consistent near "local" quality peaks.

Reception from the more distant North American continent can also be quite productive during our mid summer season, as was the case during another interesting annual dxpedition to Noordhoek from the 11th - 15th January 2011.

Noordhoek Beach - towards the north.

ECUADOR

The highlight of the dxpedition was the reception of HD210A, Guayaquil, Ecuador on 1510 khz with 500 watts. The time signal station was heard over a distance of 10 626 km / 6 602 miles - a new ULR country and the most distant 500 watt station that I've been fortunate to receive via the Sony SRF M37V.

The station was last received more than 25 years ago on June 3rd, 1985 via the FRG7 receiver and a 30 metre random antenna at Sandbaai.

My thanks and appreciation to Bruce Portzer for kindly providing the information and URL links and to Chuck Hutton for listening to the audio clip and providing some sound advice!

BRAZIL

Another highlight included the reception of Super Radio Tupi, Cachoeiro de Itapemirim on 1590 kHz with 250 watts - a personal first.

TRINIDAD

It was also a pleasant surprise to hear Inspirational Radio 730 AM, Port of Spain, Trinidad on 730 khz for the first time - a personal first and another new ULR country.

U.S.A.

The reception of KOA Denver CO on 850 khz over 14 981 km / 9 308 miles represents a new ULR logging and the most distant 50 kw station that I've been fortunate to identify via the Sony SRF-M37V.

KSL Salt Lake City UT on 1160 kHz would have been eligible as the most distant station heard with the Sony Ultralight but could not be identified during a brief tentative appearance.

No fires are allowed on the beach - but dxing with an ultralight radio is permitted!

Looking Back - Part 5

The Pilot A.C. Super Wasp receiver was available in kit form.

Part Five of the account of the early days of radio in South Africa during the 1920's as told by South African Dxer, Nick Kendall.

The candid account, in Nick's own words, provides an insight into what was involved in being able to listen in during the early pioneering days of radio broadcasting.


The Pilot A.C. Super Wasp Receiver

In or about 1927, while glancing through "Cape Town Calling" (a weekly bulletin that provided program details for the Cape Town broadcasting station), I came across an advertisement for the Pilot AC Super Wasp - an all electric shortwave receiver - Yes!

I had never heard of the Pilot Company before so I phoned Carlton Davies (who was familiar with the set). He operated from his house in Sea Point and I was invited to come out and see him. After our initial meeting, I got to know him very well.

The Super Wasp came out in kit form and when assembled became a four valve set. It was similar to the Reinatz circuit but had the advantage of a tuned RF stage and a separate power pack and speaker. Five pairs of plug-in coils were supplied giving a coverage of 500 to 17700 kilocycles (600 to 16 metres). Tuning was very broad but it did not matter as there were only a few stations on the air. If you used one today you would get at least ten stations all in a jumble.

A few months later the Pilot Company (USA) sent out a table model complete with speaker. Valves improved and special ones took the place of the all purpose ones. Screengrids were used in the RF stages and detectors, power valves in the amplifiers which of course improved the performance of the set tremendously.

A great number of American sets arrived on the market but broadcast band only. The all wave with a wave change switch was introduced much later.

The Crosley Corporation tried to market their bandbox all wave set but it was not a success. As a matter of interest they owned WLW at the time.

I cannot recall any other shortwave all electric sets available during that time and so the Super Wasp reigned supreme.

Looking Back - Part 4

Part Four of the account of the early days of radio in South Africa during the 1920's as told by South African Dxer, Nick Kendall.

The candid account, in Nick's own words, provides an insight into what was involved in being able to listen in during the early pioneering days of radio broadcasting.


The commercial sets before 1925 (as far as I can remember) were all battery powered.

It must have been at the end of that year that the "all electric" sets arrived from the U.S.A. They were all cabinet or "console" designs - beautifully and solidly built - seven or eight valves. Thanks to Rice and Kellog the sets were all fitted with Moving Coil speakers which in my opinion are far superior to present day Permanent Magnet speakers (General Electric engineers Chester W. Rice and Edward W. Kellogg designed the moving coil loudspeaker in 1925 - GD).

Well known makes were FADA, Radiola (RCA), Stewart Warner, Majestic, Stromberg Carlson, Capehart and a few isolated custom built sets. Incidently, all the dials were calibrated in kilocycles - not metres. If you were lucky you could pick up Johannesburg and Durban.

Philips was next with their two, three and four valve table models with separate speakers followed by the Loewe "Three in One" set.

Philips brought out the H.T. Eliminator which plugged into the mains. It took the place of the H.T. and grid bias batteries but I still had to contend with the accumulator and keep it charged to work my three volt home-made Reinartz-grebe set.

The Reinartz-grebe set proved to be far more sensitive than any of the commercial sets on the market so I decided to wait before purchasing an "all electric" model. I continued to use the set for broadcast band reception and easily pulled in Johannesburg and Durban.

Looking Back - Part 3


Part Three of the account of the early days of radio in South Africa during the 1920's as told by South African Dxer, Nick Kendall.

The candid account, in Nick's own words, provides an insight into what was involved in being able to listen in during the early pioneering days of radio broadcasting.

The reception of KDKA in Cape Town during the early 1920's


While reading through The Argus (Cape Town newspaper) one evening, I saw the caption "New Experimental Radio Station from the United States heard in Cape Town" or words to that effect :

" ... Mr. X from Long Street reports hearing the new experimental station KDKA - owned and operated by the Westinghouse Electric Manufacturing Company, Pittsburgh. He said that he sat up night after night trying out different coils to get down to 63 metres and eventually his patience was rewarded. He heard the announcer say "This is KDKA" followed by music. The signal faded between 4:00 am - 5:00 am. Reception of course varied ... "

(From July 1923, apart from the regular broadcast frequency of 326 meters / 920 kHz with an output of 500 watts, KDKA programs were also transmitted via shortwave station 8XS on a frequency of 63 meters / 4 760 kHz with an output of 40 kw. The shortwave station made it through to Cape Town as described in the Argus newspaper report - GD).

A couple of nights later he wrote an article entitled, "How to listen to KDKA" :

" ... The aerial and secondary coil should consist of 3 turns of no.16 bare or enamled copper wire - each turn about 3/16 of an inch apart and kept apart by ebonite spreaders. The reactor coil should be 5 turns... "

This greatly intrigued me and I decided to see what the "Family Four" could do.

After hours of winding and re-winding coils, I managed to get the set to oscillate over just one half of the condenser - I hoped that it would be the right half. At 3:00 am I patiently and slowly tuned the condenser dials. The only sound was the oscillation "hiss". I plugged the hydrometer into the accumulator (LT battery) - it showed only half charge. The next day I lugged it up to the garage to be recharged and borrowed another one.

After sitting down again with the set during the third morning (after two previous fruitless efforts), I was delighted to hear a strong carrier wave. Moving the reactor coil away from the two other coils and after adjusting the condenser a fraction, I heard music.

As I took my hand off the condenser dial, the signal disappeard (capacity effect) so I had to hold my hand on the condenser to hear the signal which meant standing about two feet away from the set in order to tune it.

Then I had an idea - using two bicycle pump clips which opened and closed like cloths pegs when attached to the condenser knob, I was able to slip a 3 ft long bamboo rod into the other end of the clip - as the panel of the set sloped, the rod rested on the edge of the table - it worked very well.

I heard an announcement which I shall never forget :

" ... This is KDKA - The Westinghouse Electric and Manufacturing Company, Pittsburgh - The Pioneer broadcasting station of the world ... "

(During late 1924 KDKA programmes were also received in South Africa via shortwave and rebroadcast via the JB mediumwave station in Johannesburg - GD)

Looking Back - Part 2

The Cape Town broadcasting studio opened officially in September 1924 and was was situated in J.N.X. building, Greenmarket Square (Photograph circa 1924).

Part Two of the account of the early days of radio in South Africa during the 1920's as told by South African Dxer, Nick Kendall.

The candid account, in Nick's own words, provides an insight into what was involved in being able to listen in during the early pioneering days of radio broadcasting.


It was about 1923 when Johannesburg started testing (and a little later Cape Town).

Five Valve Superhet

I decided that I wanted a beter receiver so I bought a home-made five valve superhet from a friend. This comprised of three staged HF (RF), oscillator, detector and two stages of LF (AF). It had thirteen controls : seven rheostats, three variable condensers, volume, potentiometer and tone.

The tuning was so tricky that it took about 10 minutes to tune Cape Town. Just imagine three stages of HF - each tuned by a separate condenser - there was no "ganging" in those days.

After a while I got fed up with the set and wrote to "Modern Wireless" for a suitable circuit. I told them that I wanted a four valve set and enclosed a postal order for 2/6 (25 cents).

The "Family Four"

The set was called the "family Four" and consisted of one HF (tuned anode), a detector and two LF's with switching arrangements so that one, two, three or four valves could be used.

They sent me a blue print (actual size) template, drilling panel, wiring diagrams (both practical and schematic). I had the panel drilled by sombody that I knew - did not take a chance myself. Ebonite had a nasty habit of splitting at the last moment. These days ebonite panels have a glossy surface. It was believed that this glossy surface acted as a conductor so it had to be sandpapered and polished again before using. You have no idea of the trouble we went to in building those old sets. I wired it up okay, switched it on and it worked fine - picked up Johanessburg quite easily.

Amplion Horn Speaker

I had an "Amplion" loudspeaker - the only one with an oak horn which produced a much better tone than other metal horns or trumpets.


Johannesburg, Cape Town and Durban radio stations

Johannesburg opened officially in 1924 (1st July) and a couple of months later, Cape Town (September 1924), followed by Durban (December 1924). We thought it wonderful to be able to switch between Cape Town, Johannesburg or Durban.

AUDIO CLIP

In September 1924, the Cape Peninsula Broadcasting Association officially launched Cape Town's radio service in JNX Building, Greenmarket Square.

Studio manager Rene Caprara (who later became the Director-General of the SABC) described those early broadcasting days during an interesting interview with Colin du Plessis, available here.

The Johanesburg Broadcasting Station cage antenna on top of Stuttaford's Building, Rissik Street. The control room was located directly below the antenna and the studio was situated on the third floor (Photograph circa 1924).

Marconi, Gecophone and home-made radio sets

Everybody was thrilled and either made or bought sets. As far as I can remember, the only sets on the market at the time were Marconi and Gecophone but nearly every shop sold components - not at all like today (1970's) when if you ask for an for an egg insulator, the chap just googles at you and says "W-w-what is that ?"

I used to try for stations after Cape Town closed down but heard nothing but atmospherics.

Looking Back - Part 1

Two South African radio enthusiats in front of a 1922 Gecophone BC2001 'smoker's cabinet' two-valve receiver (Photograph circa 1924).

The following is an interesting and fascinating account of the early days of radio in South Africa during the 1920's as told by late South African Dxer, Nick Kendall (a respected and prominent dxer during the 1970's when I first joined the SADXC).

The candid account, in Nick's own words, provides an insight into what was involved in being able to listen in during those early pioneering days of radio broadcasting.

I have transcribed and edited the 5-part series (with additional information and comments) from the 1978 July - December issues of the SASWL.


Constructing a crystal receiverIt was about 1920 when all my friends were “wireless mad”, some of whom had built crystal sets and some valve sets. One of them said to me, “Why don't you make a crystal set. It is great fun. Come and see mine”.

So we went up to his bedroom and he showed me his set which consisted of a coil of wire around a former about 10 inches x 3 inches (approximately 25 cm x 7 cm) diameter – one end of this connected to the aerial and crystal and the other to earth and one leg of the phone. The other leg of the phones was connected to the “whisker” end of the detector.

Tuning was effected by a variable condenser “shunted” across the earial and earth. In order to find a “sensitive spot” on the crystal, somebody pressed an electric bell-push. The detector would pick up the spark made by the break - and break on the bell. Then you were all set to listen in.

All there was to hear were ships (if you were lucky) in morse code (CW) and the time signal from Slangkop Light House at 11:00 pm. Anyhow, I got bitten and made up a crystal set and listened to ships on 600 metres.

John Samuel Streeter's early record broadcasts

In 1919 radio amateur John Streeter began broadcasting records on Tuesday and Thursday nights on 200 metres (initially from Sea Point and then Observatory, Cape Town - GD). It was so weak on the crystal set that I decided to build a one valve set.

(Two other prominent amateur radio enthusiasts also began broadcasting in 1919 :

Reginald Hopkins broadcast pianola music and messages from his home in Wynberg, Cape Town. With local newspaper publicity, both Cape Town stations became popular and were received across the Cape Peninsula and thoughout the Cape Province including the Karoo region of South Africa.

Further north, Arthur Sydney Innes was very successful with his broadcast of gramophone recordings from his radio station, known as 2OB, located in Observatory, Johannesburg - GD).


Arthur Sydney "Toby" Innes, broadcasting from his radio station 2OB, situated in Observatory, Johannesburg. Standing behind is Alf Goodman who became a well known radio enginner with the SABC (Photograph circa 1922).

Constructing a one valve receiver
I went to R.M. Ross & Co. (where Electricity House is today) and saw Mr. Smith who had helped me with my crystal set and bought the necessary parts : A 60 volt H.T. Battery, a 2 volt accumulator, a rheostat (for reasons unknown in those days , each valve filament had to be controlled by its own rheostat). I built my one valve set and Mr. Streeter was so loud that he had to be de-tuned. I still remember his signature tune, “Carry Me Back To Ole Virginny”.

2LO London

2LO London had just begun to broadcast and people here were trying to pick them up – the power used was 1.5 kw. Occasionally, due to unusual reception conditions they were heard here.

(2LO commenced broadcasting on 350 metres with 100 watts on the 11th May 1922 - a more advanced 1.5 kw transmitter was rebuilt and installed soon afterwards during that year, in line with new regulations which allowed for the increase in transmitter power.

The 2LO antenna, situated on top of Marconi House in London, consisted of a 100 ft long two cage system of four wires each and was suspended between two 50 ft masts - GD).

6BM Bournemouth

I tried with my own one valve set and one night as I took my hand off the condenser knob, I heard music. Boy, was I exited. As long as I kept my hand just poised above the condenser, the signal stayed. Fortunately, I was able to rest my elbow on the table so that it was not so tiring. This was not 2LO – the wavelength (frequency was not used in those days) was not right and it turned out to be 6BM Bournemouth. Like Sullivan's “lost Chord” it was not heard again.

(A sensational catch! 6BM commenced broadcasting on 385 metres with 1.5 kw on the 17th October 1923 - GD).

1932 Vintage Revere Junior Cathedral Radio

A 1932 Revere Junior cathedral radio (Photograph Gary Deacon).

Apart from dxing, I have an interest in vintage radios from the early 1930's to late 1950's - a time when families used to gather around in the evening to listen to the news or their special radio show. (Photographs of my radio collection from a bygone era are available here).

I was pleasantly surprised to discover a rare Revere Junior cathedral radio during a visit to an antique shop in Cape Town last week.


A close-up of the decorative escutcheon and tuning display.

Vintage cathedral-style radios are very hard to find in South Africa so I consider myself fortunate to have discovered one - and a real gem it is too. The radio is in good condition with an original factory finish. The pleasing cabinet design is simple yet elegant with the original decorative escutcheon, wooden speaker grill pattern and original wooden knobs which add to the charm of this set from a bygone era.


All the electronic components are intact apart from a missing valve. Aside from a few minor chips and scratches with some damage to the speaker and grill cloth, the cathedral radio looks really good after an initial repair and clean-up, especially considering its been around for nearly 80 years!

Another close-up of the escutcheon and tuning display - before and after the initial clean-up.


The Revere Radio Corporation was situated in Ashland, Ohio, U.S.A. and produced radios for a brief duration - from 1930 to 1932.

CATHEDRAL RADIOS - A BRIEF HISTORY

Cathedral tabletop radios were popular during the Depression due to their affordability (their shape required less material to make) and became icons of pre-war America. The 'cathedral' title refers to the design (the top and front resembled the ornate facades of European cathedrals). The style was short lived, however, with the majority produced between the mid 1920s and early 1930s.

RADIO BROADCASTING EVENTS IN 1932

Apart from the production of the Revere Junior cathedral radio, the year 1932 saw a number of significant happenings in radio broadcasting history.

March 1 – Both NBC and CBS go to Hopewell, New Jersey to provide live coverage of the Lindbergh kidnapping.

March 24 – A radio variety show is broadcast from a moving train for the first time, when Belle Baker hosts a show on a train traveling around the New York area. It was broadcast on the New York City station WABC. She talked first about the weather then, about local news regarding home-towns or stations of the train with the radio.

14 May – The BBC moves into its new headquarters, Broadcasting House in London.

26 May – The Canadian Radio Broadcasting Act is passed, providing for the establishment of the Canadian Radio Broadcasting Commission.

1 July – Following nationalization of the Australian Broadcasting Company, the Australian Prime Minister, Joseph Lyons, officially inaugurates transmissions from the twelve stations of the Australian Broadcasting Commission, forerunner of today's Australian Broadcasting Corporation.

19 December – The BBC Empire Service (ancestor of the BBC World Service) begins transmissions.

It was a pleasure to hear CKCW Moncton New Bruswick on 1220 kHz for the first time (A South African First) on the 21st of December 1986. The station made it through via the FRG7 and 30 metre longwire antenna at Pinelands.

I was fortunate to receive a friendly and informative QSL letter from Brian Hooper from VP Engineering, Eastern Broadcasting, in response to my reception report.

In 2001 CKCW moved to the FM band and is presently known as "K94.5" with the slogan, "Today's Best Music".

ALASKA KNLS Anchor Point 9720 kHz QSL



Alaska, at over 17 000 km away, has proved to be an illusive medium wave target for the South African DXer.

However, Christian station KNLS from Anchor Point, Alaska made it through on 9 720 kHz shortwave on the 11th October 1986 via the FRG7 and 30 metre longwire antenna at Pinelands.

The picturesque QSL card above was received in response to my reception report to the station.

Distant SOS distress call received by South African Dxer / Amateur Radio Operator Reg Sweet in 1980

Reg Sweet (Photograph from the September 1980 issue of the SASWL). 

A dramatic account which recently caught my attention while researching through various back issues of the SASWL concerns a distant SOS distress call which was received by South African dxer / amateur radio operator Reg Sweet, back in 1980. 

The heart warming story serves as a tribute to Reg Sweet whose valuable dxing skills helped save the lives on an Australian yacht in distress. 

Reg Sweet, branch correspondent of The Daily News and an ardent radio ham, received a telephone call from Toowoomba in far-off Queensland, Australia : "My name is Chris and I am Jenny's sister. It's been five dreadful days, but we're very happy now. We just want to thank you." 

Six hours or so before that, Reg had picked up an almost inaudible SOS distress signal while listening from his QTH in Durban North, South Africa. It came from the Australian yacht White Wave, a tiny sloop which had taken a hammering from hurricane Albert, lost its mast and its radio antenna, and was unaccounted for somewhere in the Indian ocean. Five days had passed. Its radio operator was the girl Jenny, sister of Chris. She held the Australian novice amateur certificate, which was just as well, for it became their lifeline. The remainder of the crew were her husband Steve and his brother Gary. It took them five days to rig up a makeshift mast, a bit of sail and a rudimentary antenna for Jenny. 

Reg was one link in a far-flung radio hams "search party" when Jenny tapped out her SOS, her call sign, the name White Wave and her position on the morse key. He was the only one to read that morse signal. It never carried to Malaysia or Australia. But he read back to the others what he had copied from White Wave and informed Durban Radio of his find while the Australian hams reported to Marine Operations, Canberra. 

Three ships were diverted. One, the Alta Queen, found the yacht within 24 hours, 160 km or so from Rodrigues Island. The White Wave saga was over. 

"Certainly, that call from Toowoomba moved me. I confess I went to bed a very happy man", said Reg.

Reg himself sent out an SOS during World War 2 when he had to ditch his Spitfire in the sea off Malta. It saved his life ...

BRAZIL

Many Brazilian stations can be heard from across the South Atlantic via the barefoot SRF-M37V from late evening until sunrise at Fish Hoek. One of the most consistent is Radio Novo Tempo, Salvador on 920 kHz (listed 25 kw/2kw nights) which can get through with fair-good peaks at times - a 50 metre longwire antenna inductively coupled to the SRF-M37V opposite my QTH at Fish Hoek resulted in an astonishing signal from the station during the evening of 29th October.

567 Cape Talk Antenna Mast at Klipheuwel, Western Cape, South Africa

It seems an appropriate time to feature the antenna mast of Cape Town's local mediumwave radio station, 567 Cape Talk. The station commenced broadcasting just over 13 years ago on the 14th October 1997.

A visit to the SENTECH broadcasting site at Klipheuwel for the first time last week has been long overdue. I managed to take a few interesting photographs of the mediumwave facility.

Another view of part of the antenna mast, showing two of the three wind turbines at Eskom’s first experimental wind energy farm at Klipheuwel (Photograph Gary Deacon).

The mediumwave facility is situated on relatively high ground clear of mountains and has long been the preferred site for a radio transmitter and antenna system. Marconi erected 245 meter high radio masts at Klipheuwel in 1923. This was part of a plan to establish long-wave radio links between London and the entire British Empire.

UNUSUAL TRANS-ATLANTIC RECEPTION !

It was interesting to read about dxer Jean Burnell's trans-Atlantic reception of 567 Cape Talk's mediumwave signal which made it through over an impressive distance of 11 425 km / 7 100 miles - recorded at 2158 UTC on the 30th April 2009 during a dxpedition at Cappahayden on the south-east coast of Newfoundland :

Ultralight Dxing At Castle Rock - 15th and 16th October 2010

Google Earth Image showing the dx locations of Fish Hoek and Castle Rock, Cape Peninsula, South Africa.

Castle Rock, Cape Peninsula, South Africa

Castle Rock is situated in a picturesque marine reserve just south of Millers Point on the Cape Peninsula. The remote conservation area has some of the most impressive views over False Bay. It is a short 20 minute drive from my QTH at Fish Hoek to an excellent elevated coastal position which is especially suited to early evening dxing. The isolated dx location is very quiet for dx reception with no local electrical noise sources to contend with - a huge advantage when trying to dig out long haul dx or distant low power stations that would be difficult or impossible to hear in Fish Hoek's more urban environment.

Google Earth Image showing the dx location at Castle Rock, situated south of Millers Point along the winding coastal road overlooking False Bay .

The South African dxer is in a fortunate position with few local stations to contend with and utilising the non-directional properties of a relatively short antenna at Castle Rock allows for the reception of quite a variety of TIO (Trans-Indian Ocean) and African/Middle East DX. It's interesting to hear distant stations fight it out on certain frequencies in line with constantly changing propagation conditions.

A visit to Castle Rock during the evenings of the 15th and 16th October 2010 produced a few interesting stations despite average reception conditions with some moderate static.

The dx location with the mountainside towards the west.

Highlights

The tentative reception of SBC Victoria, Seychelles on 1386 khz (10 kw) and fair peaks from 3ABN Busselton Western Austalia on 1629 kHz (400 watts) occured. Huge consistent "local" quality peaks from 6WF Perth on 720 kHz was quite astonishing - it is usually the most consistent of the Australian mediumwave stations received here. HLAZ Juju, South Korea owned 1566 kHz with some remarkable clear peaks - no sign of co-channel AIR Nagpur, India which has the reputation of quite a balanced fight with HLAZ. Radio Tanzania, Mwanza blew the usually dominant co-channel 6WF out of the water on 720 khz via the 220 metre BOG which was aligned towards the north, along the left hand side of the road, during the later part of the evening.

Another view of the dx location with convenient picnic site tables.
