The October main meeting of HADARC will have presentations by both Chris Williams VK2YMW and Rob Dolphin VK2DIO. See you on Tuesday at Mt. Colah Community Centre for an 8:00pm start and another great night. Order your Anderson Power Poles on the night.

Chris VK2YMW will present a short slide show some of the interesting technologies both new and old while on his cruise holiday this year with his XYL Helen. Rob VK2DIO will revisit some of the key principles of digital communications and talk about some the current Amateur digital modes.

On this coming Friday morning, 11th October, we'll be holding a working bee to clear some vegetation from the repeater site. (note that 18th October was mentioned at the September meeting, but we bring it forward a week as weneed to be doing JOTA preparation then).

The plan is to start meeting there from 8am for bacon and eggs breakfast on the public barbeque, then work the 40m net from 9am. Then, at 10am or so, spend some time chopping the vegetation. It shouldn't take long, so please come along if you are free.

Storey Park, 12 Old Berowra Rd, Hornsby NSW 2077

At HADARC's July monthly meeting on this Tuesday, 23rd, Rod VK2DAY presented 'A Practical Guide for the use of a VNA for today’s Amateur Radio Operator.'

Rod's talk covered what a VNA is and why it is the Swiss Army Knife of test gear for amateurs, the various types including some popular VNA’s from last century to now; plus, the good, the bad and the ugly of each, and how each one still has its own place in the shack today. Also covered was calibration and how to improve the test sweeps of the popular NanoVNA and some practical uses in and around the shack.

It was a comprehensive talk with a large crowd in attendance. Thanks Rod.

As discussed at the June meeting, HADARC is trialing the element/matrix messaging system for communications amongst members. Initial indications suggest that it will be a worthwhile thing.

To get access to HADARC Members room:

• Browse to app.element.io, select Create Account and follow the bouncing ball.

• Probably best to use your callsign as the username.

• Then, tell us your user name and we will invite you to the room. You will then receive an email with a link to HADARC Members room.

• You can tell us you username by sending email to the committee or via online form here

Update: Monday, 24th June

Eight hardy folk from HADARC braved the appallingly cold and wet conditions to take part in the field day.

Twelve contacts were logged on the 6m, 2m and 70cm bands.

Thanks to VK2XWB for providing some excellent shelter.

A good time was had by all.

Some photos of the event are here

Saturday 9am update

We will be operating regardless of the miserable weather

The radio setups and cooking will be undercover, plus our cars can be parked right alongside, so we can operate from their heated comfort if need be.

Rugging up will be necessary though.
