AREG April Meeting – Good Friday Park Picnic / Foxhunt / HF Activation

Posted on by

For April’s meeting (on Friday the 18th of April, the Good Friday public holiday), AREG will not be holding a meeting at the Fulham Community Centre. Instead, we’ll be trying something a bit different and meeting up in a park for a BBQ lunch, HF activation, and some fox-hunting!

We’ll be meeting at the lower section of the Morialta Conservation Park from around 11AM with parking available off Moritalta Falls Road. We’ll be near one of the BBQ areas, so look out for a red AREG flag!

We’ll have a HF station going to activate the Morialta Conservation Park (VKFF-0783) so listen out for VK5ARG on the bands! There will also be a fox-hunting (amateur radio direction finding) course set up around the park, with plenty of equipment available to borrow and give fox-hunting a go.

If you’re coming along, we suggest you bring a chair, drinks, and food for lunch (the club will provide some basic BBQ fare too).

Hope to see you there!

The next AREG meeting will be held on Friday the 21st of March at the Fulham Community Centre – Phelps Court, Fulham.

This month we have a presentation from David Rowe VK5DGR, on the ‘Radio Autoencoder’ (RADE) digital voice mode, which is in active development and available for preview right now in the latest version of FreeDV. RADE combines machine learning techniques with classical DSP to send high quality speech over HF radio at SNRs as low as -2 dB.

Doors open at 7.00pm and the presentations kick off at 7.30. Everyone is welcome to attend. If you’ve never come along to one of our meetings, we’d love to see you there, all guests are welcome. For our remote members, the meeting will be broadcast via Zoom, and the talk will be recorded for later viewing on Youtube.

After the talks we’ll all be given an opportunity to have an eyeball QSO among ourselves whilst enjoying a tea or coffee and a biscuit.
