DECEMBER IS YOTA MONTH

SOUTH AFRICAN RADIO LEAGUE DIGITAL CONTEST NEXT SUNDAY

and

THE DECEMBER 2016 ISSUE OF RADIO ZS

Stay tuned for more on these and other interesting news items.

** From Thursday 1 December to Saturday 31 December 2016, the annual
Youngsters on the Air (YOTA) event takes place and YOTA stations will
attempt to make many contacts worldwide with each other. This is an
excellent opportunity to get young amateurs in their teens and early
20s to talk with their counterparts on the air.

This is not a formal contest, but a way to get young people on the air
and to let them realise that there are hundreds of their peers around
the world that feel just the same as they do about the hobby. The main
aim is to get our youngsters on the air and for them to make contact
with youngsters all over the world. The League has registered with IARU
Region 1 as a Member Society participant and the special call sign
ZS9YOTA will be activated during the month of December.

** The aim of the South African Radio League Digital Contest is to
establish as many contacts as possible between radio amateurs in
Southern Africa using the PSK31 and RTTY modes. The contest is on the
air from 13:00 to 16:00 UTC on Sunday 4 December 2016 with activity on
80 metres (3 580 to 3 600 kHz), 40 metres (7 040 to 7 060 kHz) and 20
metres (14 070 to 14 099 kHz). PSK31 is preferred at the lower end of
the specified frequencies; RTTY is preferred at the upper end of the
specified frequencies. Please note that USB must be used at all times.
The exchange is a RST report and a sequential serial number starting at
001. See the 2016 Blue Book for all the details.

** The editor is busy finalising the December 2016 issue of Radio ZS
and it will be available for download from Wednesday 30 November from
the League's web site. In this issue, Chris, ZS6EZ, gives us an
overview of the Worked All ZS award, its history, changes and the new
challenges. Leon, ZR6LU, tells us how to use Argo to read QRSS. You can
read about the BACAR Space week and the Secunda Amateur Radio Club. Are
you balanced or unbalanced? Nothing to do with your mental state, but
about baluns to use with antennas. There are two articles, one in
English and one in Afrikaans on the subject of baluns. There is more in
this last issue of 2016.

** "The Origins of Silicon Valley: Roots in Ham Radio" Video Now
Available. The ARRL Centennial National Convention presentation, "The
Origins of Silicon Valley: Roots in Ham Radio," by Paul Wesling, KM6LH,
has been edited into a video and is now available on YouTube
http://tinyurl.com/hbmwfpd

"It tells of the interesting events in the maritime port of San
Francisco at the turn of the 20th century, as early radio was being
developed and follows the amateurs who designed new devices and
equipment to address steamship traffic plying the Pacific Ocean,"
Wesling said. "Their efforts to break the east coast monopoly on tubes
and to extend radio into the microwaves as the country approached World
War II, form the basis for what became Silicon Valley." Wesling said
the presentation traces early vacuum tube development and other
contributions by Bay Area amateurs, "and the continuing spirit of
hobbyists and collaborators that fuel today's high-tech mecca." The
presentation runs about 1 hour.

** The Ten-Metre RTTY Contest runs from 00:00 - 24:00 UTC on Sunday 4
December 2016 and the aim is for amateurs worldwide to contact and
exchange QSO information with other amateurs using Baudot RTTY on the
10 metre band. Any station may work any other station. The recommended
baud rate is 45,45 baud with 170 Hz shift. The exchange is a RST report
and a consecutive serial number starting with 001, while stations in
the USA and Canada will give a RST report and their state or province.
Visit www.rttycontesting.com/ for the rules

** The ARRL 10-Meter Contest will run from 00:00 UTC on Saturday 10
December to 23:59 UTC on Sunday 11 December. The aim is for amateurs
worldwide to exchange QSO information with as many stations as possible
on the 10 metre band; all stations operate no more than 36 hours out of
the 48-hour period. The contest exchange is a RS or RST report and a
sequential serial number starting with 001. Stations in the USA, Canada
and Mexico will send RS(T) and their state or province. Maritime mobile
stations send RS(T) and ITU Region (R1, R2 or R3). Visit
www.arrl.org/10-meter for the rules.

** Several radio amateur pioneers made their mark in history and
advanced amateur radio and/or radio science, but are now Silent Keys.
They we 1904 - W.E. Dixon Bennett, ZS5EG, pioneered amateur radio in
South Africa on spark transmission. He received the first-ever amateur
radio licence in 1904 at Pretoria and could pick his own call sign.
1921 - Paul Godley, 2ZE, in Scotland received the first Transatlantic
CW signals from the USA around a wavelength of 200 metres. 1923 - Leon
De Loy, 8AB, in France with Fred Schnell, 1MO, and John Reinartz, 1AXM,
in the USA made the first two-way CW contact on 110 metres and the
shortwave era began. 1934 - Ross Hull (ex VK3JU), employed by the ARRL,
discovered tropospheric propagation on 56 and 112 MHz. 1938 - After
working all the known DX countries, Grote Reber, W9GFZ, mapped the
radio sky on 160 MHz and discovered discrete radio sources. He became
the first radio astronomer in the world and used a dish antenna. 1947 -
Henry Rieder, ZS1P, made first cross-band contact on CW from 50 MHz to
28 MHz with Hilton O'Heffernan, G5BY, and a year later received the
first long distance TV signal from the UK. Whereas Bert Howes, ZS6HS,
at Johannesburg established the first-ever two-way DX contact via F2 on
50 MHz with Ken Ellis, MD5KW, at Port Said and followed later by ZS1P
and brother Charles, ZS1T, when they both worked Paul Saayer, PA0UN.
1954 - Dave Larsen, ZS6DN, assisted Dr Trevor Wadley in the development
of the famous RACAL RA17 receiver and the Barlow Wadley portable
receiver. He developed the frequency hopping system for the military
including Meteor Burst Communications, etc., and was later awarded the
Order of the Star of South Africa. 1958 - Denis Richardson, ZS1B,
worked JA1AXE for a world record on 50 MHz over a distance of 14 730
km. 1979 - Jack de Villiers, ZS6LN, established new world record on 50
MHz with KH6IAA over 19 305 km that stood for 21 years before it was
finally broken

** Hannes Coetzee, ZS6BZP, reports that the solar activity is expected
to remain at very low levels. No major solar flaring is expected. In
2016, there have been 25 days with no visible sunspots so far, compared
with none in 2015.

If you want to do your own frequency predictions, the expected
effective sunspot number for the week will be around 10. The 15 to 20 m
bands will provide lots of DX fun. There is a chance of weak 10 m
openings on north-south sunlit paths. Please visit the website
spaceweather.sansa.org.za for further information.
