The second of our monthly fox hunts for 2021 was held last Friday the 12th of February.
Four AREG members set out to hunt the foxes down and we were also joined by guest Brian, VK5TBC.
The usual two 144MHz foxes were deployed by Grant VK5GR as well as a bonus ultra low powered 25mW 433 MHz fox, made from a repurposed ex Bureau of Meteorology Radiosonde.
The first fox was hidden by the banks of the River Torrens in Lockleys. The second was hidden in a tree on the golfing greens just behind North Adelaide Railway Station.
The third 70cm fox was hidden roughly 400 meters from from where the first 144MHz fox was deployed.
Sigtrax is a great mobile app for plotting bearings/beam headings when when out hunting the fox.

The next fox hunt is scheduled for the evening of Friday the 12th of March. This hunt may see us start from a new location of stay tuned for more info!
The next of our monthly fox hunts is scheduled for Friday the 12th of February. Hunters are to meet from 6:15pm in the car park at Lockleys Oval – Rutland Ave, Lockleys. As usual, this event is open to all interested parties, be it members and non-members.
This hunt will again see us hunting at least one and possibly two 144 MHz hidden transmitters throughout the Adelaide metropolitan area. The frequency of the fox(es) will be broadcast on AREG’s VK5RSB Summertown 70cm repeater on 439.900 MHz a few minutes before 6:30pm with all invited to liaise and discuss their progress on the repeater throughout the night (91.5 MHz CTSS tone required on input).
We look forward to seeing you there.
On Saturday the 9th of January 2021, AREG held its monthly fox hunt but rather than driving all over town to hunt the fox, this chase was on foot instead.
Eleven hunters ranging from children to adults set out to track the transmitters down with their handheld yagi antennas and receivers. With a forecast maximum temperature of 35 degrees Celsius, the hunt was tough on all involved but a shady spot next to some barbecues provided a cool place to rest and mingle after the hunt.
The happy hunters
Seven 144 MHz radio transmitters were hidden, scattered over a distance of 700 metres along the River Torrens in Felixstow. Some were left hanging from tree branches, some buried under leaves, some under cars and even one was left sitting by the river bank.

Each transmitter had a different coloured marker attached and hunters were required to cross out the corresponding box on their ARDF tracking sheets to prove they had found each fox.
Our next monthly hunt will be announced soon so be sure to check back with us here for more info.
