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.

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.

The 25 kw signal on 567 kHz at Klipheuwel covers the entire Western Cape. Cape Town's first talk radio station is twinned with Johannesburg's 702 Talk Radio and is owned by Primedia.

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.

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.


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.

5RN Adelaide 729 kHz and 5AN Adelaide 891 Khz Barefoot Ultralight Radio QSL

Graham from the ABC kindly responded to my reception report regarding the unusual barefoot appearance of 729 5RN Adelaide and 891 5AN Adelaide on the 22nd September 2010.

Both 50 kw stations made it through to Fish Hoek, South Africa over a distance of 10 125 km / 6 291 miles via the Sony SRF-M37V's internal 5cm loopstick antenna.

Hi Gary,

I am happy to confirm your reception of:

729kHz 5RN Adelaide @ 1929Z 22/09/2010, and
891kHz 5AN Adelaide @ 1916Z 22/09/2010.

Audio : 729 5RN Adelaide and 891 5AN Adelaide received barefoot at Fish Hoek, South Africa.

I thought I'd share the unusual reception of 729 5RN Adelaide and 891 5AN Adelaide on the 22nd September 2010 , with the Sony SRF M37V via its internal 5 cm loopstick antenna!

Both 50 kw stations made it through to Fish Hoek, South Africa over a distance of 10 125 km / 6 291 miles via the barefoot Sony SRF-M37V.

891 5AN Adelaide peaked to an astonishing level at 1916 UTC - the most remarkable barefoot signal that I've been fortunate to hear from the station.


Two brief audio clips of the reception have been included below :

891 5AN Adelaide recorded at 1916 UTC on 22nd Sep 2010.

729 5RN Adelaide recorded at 1929 UTC on 22nd Sep 2010.

After an initial takeoff above 6.6 km of land from down under, the signals continued over an all-sea path across the Indian ocean, arriving above False Bay and only 1 km of land to the dx location at Fish Hoek, over 10 125 km / 6 291 miles away.
