AREG Fox Hunt Fridays – February Hunt Report

Posted on by

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.

REPORT: AREG Handheld ARDF BBQ Picnic

Posted on by

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.

AREG Handheld ARDF Picnic – 12:00pm Saturday January 9th

VK5ZM hunting 2m “Foxes” in 2019

The next AREG hosted fox hunt is planned to be an ARDF “hand held – on foot” style event held in Drage Park / Riverside Park, in Felixtow, just 6km north east of the city centre (near the Kelmzig O-Bahn bus interchange). Members and visitors are welcome to join us in the park from 12.00pm, Saturday 9th January 2021.

AREG will deploy a minimum of 5 beacon transmitters on the 2m amateur band (144MHz). The challenge will be to see who can find all of them the fastest!

To participate, you will need to do a SA MyGov COVID Checkin with us at the start, and ideally bring along your 2m (144MHz) direction finding antennas and receivers. We will do timed staggered starts and you will be free to hunt the transmitters in any order you like!

For those who dont have any equipment, take a look at (this design) by NT1K! It is very simple and quick to put together! Add a variable attenuator and a receiver and you are away!

For those who aren’t sure, AREG is hoping to have at least 1 or 2 loan sets of gear available, based on the very popular VK3YNG sniffer receivers, or we can arrange to buddy you up with one of the club members who do have equipment so you can get a first taste of fox hunting ARDF style.

For those not into fox hunting, but who would like to gather and welcome in 2021 with all of us at AREG, we are also promoting this event as the AREG Summer BYO Picnic for 2021.

This will be a COVID Safe event with family groups spread out across the banks of the Torrens to observe social distancing requirements. AREG has picked this location as it has lots of amenities for all of the family. There are public BBQs, a kids playground and public toilets in the area as well as ample parking in the Drage Reserve car park. The marshaling check-in point will be marked with AREG Flags and will be located on the south side of the river Torrens near the Riverside Park western BBQ area (west of the play ground closest to the Drage Reserve Car Park).

We will also endeavor to have someone monitor the VK5RSB 70cm repeater on 439.900 (91.5Hz CTCSS access tone) to help guide anyone in who is having problems finding us.

We look forward to seeing you there!

Friday Foxhunts: Next Adelaide hunt 11th December 6.30pm

Posted on by

On Friday 14th of November, three hunters set out to locate the two foxes that were hidden by Theo, VK5IR. The hunters were Mark, VK5QI, Louis, VK5FLY and Allan, VK5MAD. The first fox was hidden low in a tree at Victoria Park, south of the CBD and the second fox was stuck to the flying fox at a playground in St Clare, next to the St Clare Recreation Centre.

Both Mark and Louis were successful in locating the fox at St Clare and this was really a job well done as this fox only outputs 100mW so was very hard to hear. Mark was also successful in locating the other fox at Victoria Park which he found first before setting off for the low power fox. Unfortunately Allan had radio issues and called it a night early but has vowed to return for the next hunt.

The next hunt is planned for the evening of Friday the 11th of December and with hunters meeting at Lockleys Oval, Rutland Avenue Lockleys from 6.15pm and the hunt will commence at 6.30pm. Everyone is welcome to join in and we hope to see you there.

 

AREG 2m Fox Hunt Fridays

Posted on by

Have you ever heard of Fox Hunting? Do you remember the days when teams of people chased 2m hidden transmitters all over town? Would you like to join in the fun? The Amateur Radio Experimenters Group is commencing a new series of “Hidden Transmitter hunts” or “Fox hunts” as they are known on the 2m band over the summer daylight savings season this year.

The first event will be held on Friday the 13th of November. This will be a cross-town hunt with a two metre fox being hidden somewhere within the Adelaide metropolitan area. Anyone and everyone is welcome to join in.

The hunt will commence from the car park of the Lockleys Oval, Rutland Avenue Lockleys. Hounds are encouraged to gather at the start from 6.15pm. The fox will begin transmitting at 6.30pm. The fox’s frequency will be announced via the VK5RSB 70cm Summertown repeater on 439.900 MHz just before the hunt begins. Hunters are welcome to liaise via VK5RSB during the event (note that a 91.5 Hz CTCSS tone is required to access the repeater).

This will the first of many monthly fox hunts hosted by AREG over the coming months which will be announced on our website and via our Facebook page as well as the local VK5 WIA news.

So dust off your ARDF gear, we look forward to seeing you there!
