Elizabeth Amateur Radio Club

Our club favours VHF, UHF, microwaves, light and contesting.


Water Tower access issue

The club has considerable assets (repeaters, beacons, APRS Digipeater etc) in the Old Water Tower at Elizabeth. Site access has been stopped to ALL users because of an OH&S issue. No one knows when the issue will be finalized, and it may be "years." If we have an equipment breakdown, then it may not be fixed for a very long time.

A DVB-T ATV transmitter on 445.5 MHz is under construction at a members house, and will be shifted to Ye Aulde Water Tower when it is finished. It will be a transmitter only, not a repeater. The input is via the internet. At this stage, it is very low power because digital tv requires extremely low distortion A Class amplifiers, so expect about 12 watts when it is on the water tower. The frequency is a standard commercial television frequency and should be able to be viewed with a normal tv.

APRS Digipeater

The Elizabeth Amateur Radio Club operates an APRS digipeater on 145.175 MHz
The club may put up a UHF digipeater in the near future, using a modified Vaisala radiosonde and a receiver.


The Elizabeth Amateur Radio Club members are a diverse bunch of Amateur Radio operators based around the city of Elizabeth, north of Adelaide, South Australia.

Our members have various interests.

  • Several are on LF at 137 and 475 KHz.
  • Most still use HF despite the situation with the sunspots.
  • VHF has 50 MHz and 144 MHz active.
  • UHF has 432 MHz, 1296 MHz and 2.4 GHz very active.
  • SHF has 3 GHz, 5 GHz and 10 GHz active with a couple of bare mixer 24 GHz transverters in use.
  • EHF has several members building 47 GHz, 76 GHz and 122 GHz equipment.
  • LIGHT COMMUNICATIONS has become the latest high interest subject with two of our members having set the VK5 record for voice comms on home made light transmitters and receivers, and the NATIONAL RECORD for data transmission. Well done chaps!
  • Digital Amateur Television DATV has just started.

Our clubroom is at “The Grove Venue,” 5 Burdett Street, Elizabeth Grove, 5112.
Postal Address is PO Box 8 Elizabeth 5112 SA

  • EVERY Sunday morning at 09:00 is the rebroadcast of the WIA News on 1.843 MHz LSB and the VK5RLZ repeater 439.975 MHz 91.5 Hz tone with callback. There probably will be some Digital ATV transmissions at the same time on 445.5 MHz. This is a standard DTV channel.
  • First Wednesday of the month are the business meetings. Doors open at 19:30 for a 20:00 start.
  • Second Wednesday of the month we meet on air at 20:00 on our 2 metre repeater VK5RLZ 146.625 MHz no tone
  • Third Wednesday of the month are the Tech Nights and we usually have a Guest Speaker. Doors open at 19:30 for a 20:00 start.
  • Fourth Wednesday of the month we meet on air at 20:00 on 3.620 MHz SSB +- QRM.
  • EVERY Friday night at 20:00 has 2 metre SSB/CW skeds on 144.150 SSB
  • There is an informal Morning Tea Net at exactly 10:00 on our 70 cm repeater VK5RLZ 439.975 MHz 91.5 Hz tone which is on the Old Elizabeth Water Tower near Edinburgh.
  • Many members meet in person 10:00 Wednesday mornings with NERC members at the Tea Tree Gully Library at 571 Montague Rd, Modbury SA 5092 for informal coffee and cake. This has become a very well attended group
  • The regular VHFers and above make their own arrangements.

The current excitement is around 3 GHz using old patch panels obtained from the  Geelong Amateur Radio Club and on 1296 MHz using transverters.

Other microwave activity revolves around contests, particularly the VHF-UHF Field Days, where our club members have been particularly successful.

The club is also a member of the Wireless Institute of Australia
