MAD Day

2018-10-16

Last Sunday's MAD Day (Microwave Activity Day) was a resounding success.

Keith VK5OQ has suggested the club submit an article to AR Magazine. The closing date for the Nov-Dec issue is soon (this week ?) so could those who took photos please organize them for Keith, and write up a short segment about what worked, what didn't work and why, and how much FUN you had, especially if you were hailed upon. We have our regular Wednesday club meeting this Wednesday on 2018-10-17 at 7:30, so that would be a good time to consolidate the event.Photos 2018

About

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 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.
  • EHF has several members building 24 GHz, 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 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

Club Projects

2018-07-25: A suggestion was made at the July 2018 Tech night to have a club project of a GPSDO (GPS Disciplined Oscillator) based on a project that David VK5KK has working. It has a GPS, a 10 MHz disciplined oscillator and a processor of some sort with a LCD display. It shows time and date, (could this be rearranged to be date and time in 2018-07-25 13:14:15 format?). This function alone would be really great for contesting, to know ZULU time and your location, possibly with Grid Squares as well as Latitude and Longitude.

2018-07-25: From VK5WX Graeme: For some time, I have had the idea to remotely control a radio in the car with a control box that could be fitted into a standard DIN format car console slot. My idea is to have the essential things like off-on, volume, mute, frequency display, mode select (USB, LSB, CW, AM, FM etc) mike input, speaker and or earphones output, separate PTT, CW key input (with Iambic keyer built in) these would be great for portable – contesting operation … the list goes on.
