Concept:Experiment with the design concepts and theory of the high gain vertical for UHF. A dipole is a 1/2 wave.Theory:A radio frequency energy is the same as light energy, travelling in a magnetic and electrical wave shape, 90 degree separated… Download the full PDF article here> Created by VK2JMJ
Read moreOn the 16th July 2023 VK2EXA Greg made contact with VK3YE Peter who’s POTA park station was at Seaford Wetlands Reserve out of Melbourne. The contact was made at Peter’s end from his Solderless Breadboard ATU. The video is about 27 minutes in duration. In the YouTube video Peter describes how a handful of capacitors and inductors can form an […]
Read moreA fun little project I did over a couple of days was making this little 6 element yagi for 70cm. There are so many designs and ways one can do this so after some reading of different designsand measurements I came up with this (photos below). I decided to go for a dipole driven element fed by a “Bazooka Balun”. […]
Read moreThe Portsdown Digital Amateur Television Project. This document covers the general layout, construction, assembly and setting up of Portsdown Digital Amateur TV system. Before starting in DATV it is highly recommended you read this document in its entirety to understand how the system operates and which hardware you will need. Download the PDF document>
Read moreAn issue confronting Raspberry Pi users is SD card corruption due do improper system shutdown. Ordinarily before removing power from the Raspberry Pi, one should execute the “sudo shutdown -h” Simple routine can be incorporated into the system, sensing either an operator shutdown or a power failure.

Read moreDigital Voice Radio just became a lot easier “In the not so distant past”Sounds like the preamble of a book or movie. If you, are about to make the move into digital radio, you will be presented with choices, these will have an impact on your pocket and whom you will be able to talk to. Looking for what gives […]
Read moreWith any electrical signals, being the transmission over wires or radio, or the process of converting analog to digital or for whatever purpose, this will require some form of signal conditioning. The reason is that the converting process creates problems either to obtain acceptable signal to noise ratio or signal linearity. With digital conversion of an analog system the technique […]
Read moreKenwood Microphone MC60A Modification – Another use for the SSM2165 The Kenwood MC60A with preamp, suffers from RF feedback, a search on the web reveals the extent of the problem. For the many looking for solutions to this problem. There exists an error on the user documentation, that shows the microphone audio wiring as reversed from one socket to the […]
Read moreRadio to Computer Interface Audio Conditioning Project This project allows automatic level control of audio going to and from any bridging systems, be it from a computer or even a radio repeater adjusting the audio from large variation in levels. The project became obvious as a must for any EchoLink system where the operator wishes to setup an RF link […]
Read moreAdding a Pan Adaptor using your computer and a Software Defined Radio, can be dead easy on some radios, with others requiring modifications to the radio, something that can be easy to do or the opposite. The Kenwood TS590S unlike the newer TS590SG does not easily lend itself to connecting a Software Defined Radio There are modifications that involve fitting […]
Read moreThis is the antenna for you guys who want to get on HF effectively, and haven’t too much space or cash to throw around. Actually, it’s a design from ZS6BKW (aka G0GSF), similar to the G5RV, but it actually resonates on five bands, (well 6, actually) and doesn’t rely on a tuner (ATU) to make it work. The design appeared […]
Read moreHINTS AND KINKS – by Scotty VK2KE Speaker impedance When connecting a speaker to a receiver watch the impedance of the speaker so that it matches the rig or receiver, if you connect a 4 ohm speaker to a receiver that is designed for 8 ohms, it may overload and destroy the audio amplifier transistors in the receiver. Speaker quality […]
Read moreFrom the shack of John VK3HJQ. I’ve had this problem with my Icom IC-290H Radio for years, that every time I turned off the power in the shack the radio would lose all its memory channels and I would then have to reprogram them all back in. This was a simple process as there is only 5 channels in the […]
Read moreThis article was submitted by Mark VK3ASC. I was in the local Jaycar store in Albury and saw a poster advertising the local Amateur radio club in Albury Wodonga is running a foundation licence course on the 20 – 21st August 2016. What is a foundation licence? Well it’s a basic entry in to amateur radio that is an easy subject […]
