Adelaide Hills Amateur Radio Society (AHARS)
The Adelaide Hills Amateur Radio Society was formed on the 10th February 1983 at the Blackwood War Memorial Hall. The Society was incorporated on July 21, 1983.
Whilst this was the formal date, it also considers that it has a historic link with the early Blackwood Radio Club formed in 1924 and which was active until around 1937.
Early in 1998, because of the problem of remaining viable with their falling membership, the Lower Murray Amateur Radio Club approached AHARS on the question of joining with AHARS. Later that year they became part of AHARS.

The Radio Shack
Early in 2011, AHARS made an agreement with the Girl Guides of Hannaford St. Blackwood to make use of their shed. Starting Saturday May 7, and continuing on many following Saturdays into August 2011, AHARS members fitted out the building to turn it into a comfortable room for the Club's amateur radio use. More detail can be found at The Shack.
The "Shack" was officially opened on Saturday September 3, 2011. An address was given by the AHARS President David Clegg VK5AMK, the Mayor of Mitcham Michael Picton, the State Commissioner for Guides Wendy Davis, and the WIA Director Chris Pratt on behalf of the WIA. The opening was carried out by Christine Taylor VK5CTY in memory of her late husband Geoff Taylor VK5TY, the longest serving AHARS President.
Since the Shack was officially opened it has been used for various practical activies on Saturday mornings,
such as the workshop to convert computer power supplies to 13.8V at 20A.

A Club Amateur Radio Licence (call sign VK5BAR) was granted soon after the first meeting in Feb 1983.
The Club station first went on air on March 21, 1983 on 3597 kHz. A Club frequency was set up on 147.35 MHz at the Club meeting in June 1983 For many years, a Club network has been operated on week nights at 7.00pm local time on 28.345 Mhz
On March 31, 1993, a net commenced on the Adelaide VHF Repeater 147.00 MHz on Mondays at 8.00pm local time. This net still operates today.
During 1986, AHARS was involved in the South Australian Jubilee (J150) Celebrations operating an Amateur Station under the VK5BAR call sign and involving many AHARS operators led by John Hampel VK5SJ as Convenor.
Commencing in 1988, the Club has rostered operators using the Club VK5BAR call sign to provide the relay on 10 metres for the WIA Sunday Morning Broadcast and the call back which follows.
Following the re-organisation of the WIA and the winding up of the previous S.A. Division of the WIA, the ownership and maintenance of the WIA 2 Metre repeater station (VK5RAD) at Mt Lofty was accepted from WIA by AHARS in January 2005. Maintenance has been continued by Committee member Barry Williams VK5ZBQ/VK5BW.
This was first established in November 1986 and has been held on a Saturday in November of each year up 2007 at the Westbourne Park Community Hall, Goodwood Road.
The Sale was held in in November 2008, September 2009, November 2010 and November 2011 on a Sunday at the Goodwood Community Centre, Rosa Street, Goodwood.
The 2010 event was also attended by Guest Speakers Michael Owen VK3KI (WIA President), Peter Wolfenden VK3RV (History & Beginnings of WIA), AREG members (Project Horus, Recent Ballon Launches).

AHARS has participated in this March event in the field over a number of years:
This contest was initially named the "National Sprint" but was soon renamed the "Australian Sprint". There were separate sections for phone and CW, each of one hour duration, and held on consecutive Saturday nights in July.
The contest was first run in 1986 and then run every year following up to around 2001. It ceased when interest in its participation waned.
John Hample VK5SJ co-ordinated the event from 1986 to 1988. David Box VK5OV took over in 1989 and continued until it was last held.
Equipment and operators have been provided for amateur radio exhibits at the following:
AHARS have provided an amateur station and operators at Blackwood in a number of Octobers for this event. Some of the years are 1984, 1985, 1986, 1997, 1988, 1989, 1992, 1993, 1994, 1995 1996.
Christmas end of year Club dinners and mid year dinners have been held each year at the Blackwood RSL Club since December 1991, except for mid year 2000 when it was held at the Country Club, Belair National Park. Bryan Scott, who was a member of the RSL Club, originally instigated the RSL as an on going venue.
In later years, Christmas Luncheons were held as an alternative to the previous Christmas Dinner functions at the following venues:
"Auntie Bet's" of Summertown in Dec 2007
The Mount Osborne Golf Course Clubrooms in Dec 2008 & Dec 2010.
Mt. Lofty House, Crafers in December 2009.
Mid Year dinners were also held at the following:
Mt Osborne in July 2009
Fresh Choice Restaurant in July 2010.
A Special Luncheon was held at the Blackwood RSL on November 28, 2010
For some years, members of AHARS have assisted the Wireless Institute Communications Emergency Network (WICEN) in providing radio communications in the field for various automobile and cycle rallies. In particular, since 1998, they have assisted with the Classic Adelaide Rally held over five days near the end of each year and since 2001 have assisted with the Coopers Car Rally held each mid year over a two day week-end.
In 1998, the AHARS agreed to financially support Rob Gurr VK5RG in providing a HF gateway to the packet system. Due to the efforts of Rob and several other members of the Club, the equipment went on the air from Rob's QTH in March 1999. It was re-installed at the Water Tower (Hq. of Elizabeth Radio Club) as a more permanent location early in 2001. The facility was taken out of service early in 2002.
During the period when Geoff Taylor was President, he gave an award at each AGM night for a member who he considered had given outstanding service to the society during the financial year which had just terminated. Unfortunately, the name of each nominee was not recorded in AGM Minutes and it has not been possible to include all of those who received the President's Award in the list which follows. If any member can give us more information, we will be pleased to add further detail to the list.
In latter years, an award was set up in memory of past member Dennis
Greig by his widow and presented each year to a member for outstanding service.
In 2009, the club award arrangement returned to the original President's Award.
