With the return to level 1 this week, Wellington VHF Broup (Branch 74 NZART) is going to have its 50th celebration dinner at 6:30 pm at the meeting room in Tawa Community Centre on Thursday 24 September.
They will have a few pizzas, but members and visitors should feel free to bring something to eat. Soft drinks, tea and coffee will be provided, but you can bring anything else you like.
This will be followed by their regular main meeting and special guest speaker, Shalini Divya who will be giving a presentation on her research into Aluminium-ion batteries.
Our next shed workshop is on 4 October from 1pm to 3pm at Bernard ZL2BD’s QTH at 1 Winsley Tce, Churton Park. All are welcome. Tea and coffee will be available at the conclusion of the workshop.
The topic involves summarising further RX Magnetic Loop experiments that Bernard ZL2XJ has undertaken.
Is a broadband RX loop as good as a tuned loop? Do you still get an advantage in using a phasing device to null out noise? Would a RX only loop be better than a TX loop for most amateur operators? What do RX loops look like? How big does an RX loop need to be to cover100kHz to 30mHz? All your questions will be answered!
This shed workshop will be available online as well through Zoom. Registration details to come shortly.
Download the PDF document with all of today’s Zoom session content. We will also be making available the video of today’s session as soon as it has been edited.
Mag Loop antennas are becoming increasingly popular transmitting antennas for the lower frequency HF bands. This is because of their rather small size being suited to city residential sections or apartment buildings and the improved receive signal to noise performance over traditional wire antennas.
Online Shed Workshop
An online Zoom workshop on Sunday 6 September from 1300 hours NZST will cover the design and DIY construction of a 40m Magnetic Loop Antenna. (Mag Loop).
The workshop features a PowerPoint presentation by Bernard Robbins ZL2BD and an opportunity to have questions answered. The full content of the presentation will be published on the website ZL2WB.com in the week following the Zoom meeting.
Purchase the High Voltage Butterfly Capacitor for $80 incl. postage
Branch 50 NZART recently launched a trading table. The branch plans to sell a range of kitsets and books to amateur radio operators. Our kits will be designed to get more people active in our hobby on the HF bands and to make construction projects easier for the ordinary amateur operator – simple kits that make a difference to your operating experience.
The 40m magnetic loop capacitor is now available for sale through our trading table. It is just $80 including shipping for the full kit. To order go here. To download more information or the manual go here.
Don’t take too long to place your order as the level of interest has been high from ZL amateurs, and we have only a few left in stock. There may be a delay of a few weeks before these are back in stock once sold out.
