Adelaide Hills Amateur Radio Society (AHARS)

Establishment & Amalgamation
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.

Club Radio Licence and Radio Networks
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 VK5ZBD.
Special Events organised by the Club November Electronics Sale This was first established in November 1986 and has
been held in November of each year at the Westbourne Park Community Hall,
Goodwood Road. Co-ordination of this event has been led by the
following: Club Conventions The first WIA organised Club Convention took place
at "Parnanga" O'Sullivan's Beach in April 1984. Delegates from AHARS were sent to this Convention
and in following years. Delegates have included: John Moyle National Field Day AHARS has participated in this March event in the
field over a number of years: National Sprint supervised by
AHARS This was first run in1986 and has been run every
year since, up to 2001. John Hample VK5SJ co-ordinated the event from 1986
to 1988. David Box VK5OV took over in 1989 and has continued since. Amateur Station Displays Equipment and operators have been provided for
amateur radio exhibits at the following: Scouting Radio Jamboree of the Air
(JOTA) 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. Club Dinners 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. As an alternative to the usual Christmas Dinner, in Dec 2007 a Christmas Luncheon was held at "Auntie Bet's" of Summertown Assistance to WICEN in Car and Cycle Rallies 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. HF Bulletin Board System 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. Outside Visits Members Activity Nights Club Awards 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 reconstruct an accurate running list for the historic record.
However in latter years, an award was set up in memory of past member Dennis Grieg by his widow and presented each year to a member for outstanding service. The following members have received this award: John Elliott VK5EMI (2003), Bryan Trott VK5SV (2004), Geoff Taylor VK5TY (2005), Jim Tregellas VK5JST (2006), Graham Dicker VK5ZFZ (2007), Christine Taylor VK5CTY (2008).
