Amateur Radio Magazine Issue 4 Is On Its Way!
Date : 16 / 07 / 2026
Author : Roger Harrison VK2ZRH
The theme for Issue 4 is Basics & More
Contents for the issue range across advice for new contesters, what’s “the deal” with end-fed-half-wave antennas,
building a 1-to-1 balun for HF through UHF and not a ferrite core in sight, to answering the nagging puzzle of
why everything is built around 50 Ohms.
Contesting is for fun.
For some amateurs, it’s serious fun.
If you’re new to contesting, we have an article on Ten Tips to Untangle the Tripups.
Before you call CQ Contest, it’s a “must read.”
Those intent on tackling the technologies encountered in communications gear, you can get to grips with operational
amplifiers, or op-amps for short.
With the cover featuring a topless transistor, wait till you see a topless op-amp! Author Elmo Jansz VK7CJ explores
the basics of op-amp circuits, step-by-step.
Speaking of circuits and circuitry, Part 3 of Lou Destefano’s Foundation class transceiver project for 80 and 40 metres
covers the VFO and the two front panel displays.
Meanwhile, Garry Gibson VK2DBN answers the questions about 50 Ohms that have hung in the air for ages – why was that
value chosen, who thought up 50 Ohm coax, and why wasn't a different value chosen?
The Wireless Institute of Australia is Australia's national amateur radio peak body, powered by volunteers who contribute
their time, expertise and passion to advance amateur radio for the benefit of the entire community.
