SILENT KEYS

It is with regret that it has to be announced that the keys of two
radio amateurs went silent a few weeks ago.

The key of Ray Langton, ZS6EJ, went silent on 2 November 2011. The key
of Andries van Wyk, ZS6CEG, became silent on the 9th December.

Our sincerest condolences to all the relatives and friends of the

NOVEMBER/DECEMBER RADIO ZS IS THE MAIL

Another great-read issue of Radio ZS is in the mail and available on
the web. Besides all the regular columns you will find on page 6 an
article written by Bert Howes, ZS6HS, which was first published in 1958
in "Kommando", the journal of the Union Defence Force. Bert who was a
member of the SARL since 1932, passed away on 2 December 2011 at the
age of 96. It is an article worth reading. The edition also has
information about various awards and in the RaDAR article Eddie
Leighton discuss the various ways people view the RaDAR concept.

If you are not a member of the SARL yet and would like to a sample copy
of the November/December edition of Radio ZS, send an email to

inbox.

TRANSATLANTIC AMATEUR RADIO BALLOON IN FLIGHT

An amateur radio balloon carrying APRS that left the United States
mainland and headed across the Atlantic Ocean toward the European
continent, made it.

Ron Meadows, K6RPT, of the California Near Space Project launched four
high-altitude balloons on at 00:00 UTC on Monday, 12 December. The
balloons were expected to come down somewhere in the midwest US but one
identifying on APRS as K6RPT-11 decided to take a cruise on the jet
stream.

After departing US soil over New Jersey at an altitude of 110 000 ft it
crossed the Atlantic Ocean overnight, amateurs in Southern Europe were
asked to tune their gear to 144,390, which is the APRS channel used in
the United States. They were then requested to assist in tracking
K6RPT-11 on its pass over Europe.

The question at the time was where would it land. The answer came early
in the morning of December 14th. At the time the balloon was out over
the Alboran Sea in the Mediterranean when APRS tracking showed it
suddenly descending. The last report via EB6AOK showed it at 14 558
feet and travelling at 35 miles an hour. At that point its assumed to
have fallen into the sea but not before travelling over 7 000 statute
miles 11 200 km) at well over 100 000 feet (30 500 m).

What is little known is that amateur radio experiments with balloons
were first made in South Africa with a large team of radio amateurs led
by Tony Reumerman, ZS6AOG, John Willescroft, ZS6EF, and Dave Woodhall,
ZS6BNT. At the time ZS6AKV made a presentation at an AMSAT conference
in the USA which started the ball rolling in other countries.

RUSSIAN MILITARY OFDM OPERATING ON 40 METRES

The IARU Monitoring System newsletter reports that the Russian military
have been transmitting on 7 000,8 kHz using OFDM 112 coding. The
transmitter generating the unwanted noise appears to be located near
the city of Severomorsk.

But Russia is not alone on the 40 metre band. The IARU also notes that
Chinese Over the Horizon Radar has turned up several times on 7 MHz in
the evening hours. It sometimes occupies as much as 280 kHz of spectrum
and has been heard up to 7 040 kHz using the well known sweep rate of
43,5 sweeps per second.

Reports from South African Radio Amateurs are invited. Please send it
to ZS1FCS, email .

RADIO TECHNOLOGY IN ACTION

PROPOSED AMATEUR MF ALLOCATION RECEIVES A BOOST

The proposal to allocate a part of the medium frequency band to the
amateur service at the World Radio Conference in 2012 received a boost
this week with the release of the Asia-Pacific Common Proposals that
were developed at the 5th Meeting of the APT Conference Preparatory
Group for WRC-12.

During this meeting, the various nations of the Asia-Pacific region
discussed many of the issues that will be addressed at WRC12 and
attempted to come to a regional consensus position.

The proposal of interest to the amateur service is "to consider an
allocation of about 15 kHz in parts of the band 415 - 526,5 kHz to the
amateur service on a secondary basis, taking into account the need to
protect existing services" and this proposal was supported by a
comfortable margin of Asia-Pacific administrations responding to the
voting request. The successful development of a regional position
supporting an amateur MF allocation increases the chances that the
proposal will be accepted at WRC-12.

The amateur radio service is represented at the APT meetings by
delegates from Region 3 of the International Amateur Radio Union and by
members of national amateur radio organisations who are part of
delegations from each national administration.

LEN WELLS AMATEUR RADIO SPIRIT TROPHY

The Len Wells Amateur Radio Spirit trophy for 2011 was presented to Tom
Cooper, ZS1PS, at the False Bay Radio Electronics and Computer Club end
of year function on Saturday 10th December. Tom has been a dedicated
worker for his club for many years and is a committee member and the
Editor of their Newsletter DIALOG. In spite of being a big C survivor,
he spent many week-ends building up their club house. Tom, 80 years of
age, has 60 years of unbroken membership of the SARL.

That's true Amateur Radio Spirit! Congratulations Tom, may you still
enjoy amateur radio for many years to come.

PORT ELIZABETH AMATEURS ARE LOOKING FOR COASTAL VHF DX

VHF amateurs in Port Elizabeth are looking for the VHF holiday makers
along the south and east coasts of South Africa. They know that a
number of amateurs will be spending their holidays at the coast, and
some of them will take VHF gear along with them, such as Rassie, ZS1YT,
and Derek, ZS5Y, who will be holidaying on the southern coast.

Some local amateurs will monitor the southern coast while others are
watching the eastern coast and will alert each other about signals. The
calling and listening schedules will be in the evenings between 19:00
CAT and 20:00 CAT on 144,400 MHz FM, and from 20:00 CAT onwards on
144,200 MHz USB. Also keep an eye on hot humid days when fantastic
Tropo openings can occur.

Since all the local VHF amateurs are horizontally polarized and some
equipped with high gain Yagis, the minimum requirement on the other
side of the VHF path will be at least a horizontal dipole. The amateurs
with the big Yagis will make up for the lack of antenna gain on the
other side, and contacts longer than 400 km can be expected.

PROPAGATION REPORT

Hannes Coetzee, ZS6BZP, reports that the solar activity is declining
with no threats of strong flares. The sun's surface is still peppered
with smaller sunspots promising exciting HF conditions.

For the people doing their own frequency predictions the expected
effective sunspot number for the week will be around 83.

All the bands from 20 to 10 m will provide lots of DX fun with the
higher bands typically opening first and the lower bands opening later
during the day. 6 m is also active with TEP openings from time-to-time.

Please visit www.spaceweather.co.za for further information.
