Adelaide Hills Amateur Radio Society (AHARS)

HISTORIC RECORD

Prepared by AHARS Historian Lloyd Butler VK5BR

Updated June 20, 2008

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.

  • Gordon Welsh VK5KGS - nominated at meeting May 1989
  • Marshall Emm VK5FN - nominated in late 1990 when he returned to USA

Club Radio Licence and Radio Networks

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 VK5ZBD.

  • At the up river venue of Wombaroo. Geoff and his XYL Christine built their own home away from home on a scrub block near Swan Reach. This he called "Wombaroo" and each year when the John Moyle National Field Day was held, he invited members of the Club to live in (or out) at Wombaroo and operate in the name of the club call sign (VK5BAR) from that location. Since 2007, Wombaroo has been owned by Rob and Tina Clogg (VK5ZHW and VK5TMC). The field Day has operated from Womberoo in 1992 and subsequent years 1998 to 2007 inclusive.

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.

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).
