Meeting with ZL2 Councillors

Daniel – Central Region NZART Councillor

On Tuesday 10 September, a combined Wellington branches meeting held at Branch 42 HQ welcomed the three councillors (Daniel and Ben in person, and Phil on the end of a cellphone). Members from all six Wellington region branches were present including three from Branch 50 NZART. The meeting primarily focussed on the challenges that NZART faces in terms of retaining and expanding membership (and amateur radio more generally), and how to improve the relationship between NZART and members. Those attending appreciated the willingness of Daniel to travel to Wellington especially to meet with local amateurs, and to openly discuss the challenges.

Blackwood Cup Competition – 2019

Our regular meeting in September 2019 represents the annual Blackwood Cup competition. Bring along your homebrew construction project to be in to win the right to hold on to the cup – which has been contested since 1930 (won that year by ZL2BC)! Doug ZL2AOV SK was the winner in 2018. Who will win the cup in 2019?

QTH: Mike ZL1AXG – 2 Derry Hill, Churton Park. Sunday 22 September 1pm -3pm. Afternoon tea available. All welcome.

Phasing two antennas & TX/RX switching – Shed Workshop – 6 October 2019

Bernard ZL2BD will talk to the challenges of switching between RX and TX antennas on your rig and demonstrate a simple circuit (not suitable for break-in keying) to allow us to use our active antenna  or mag loop antenna on RX and our standard antenna on TX (or you can buy one like the MFJ unit above).

He will also demonstrate using a phasing circuit with two RX antennas (through a full 360 degrees) to reduce noise levels.  This can be used with  two active antennas, or in fact, any two antennas.

All welcome at Bernard’s QTH: 1 Winsley Tce, Churton Park. Sunday 6 October 2019 1pm -3pm. Tea and coffee available after the workshop talk.

Active Antenna Kit – Shed workshop #2

The Active Antenna kit partly built

The second shed workshop on Active Antennas involved a construction day … with soldering irons out and smoke from the burnt plastic wafting through John ZL2XY’s QTH.

The kit was made available to all Branch 50 NZART members wanting to build an active antenna. This involves two enclosures – the active RX unit at the antenna site – where the whip antenna is mounted and powered over coax, and the shack unit that provides for the power over coax. Assemblers found they were able to build about half of the circuit in the allotted time, and the rest will be done at their own QTH.

With the next shed workshop on 6 October 2019 at Bernard ZL2BD’s QTH will focus on antenna switching and phasing of two RX antennas to reduce or eliminate noise. This is a logical follow on and should be of heightened interest with club members getting their active RX working over coming weeks.
