I have, for quite a while, provided modified versions of the code for my projects free of charge. However, the cost of webhosting for this site has tripled in the last couple of years and the little I make out of the pcbs I sell goes nowhere near covering this cost.
As of October 2017, I will be asking for a donation in exchange for providing custom modified code for my projects to help keep this site available.
As a lot of people have pics of things unrelated to ham radio on their websites, I thought I would add a couple of my own (Scroll down for site updates). Banjo, our Red Heeler/Koolie cross at 4 months old. And at 12 months old (Feb 2016) enjoying his birthday breakfast treat of banana on toast. A new addition to the family, an 11 week old kitten (end July 2017), rescued by Banjo after being trapped between a water tank and fence. Her name is Storm after her colouring and it's eating a bit of toast and jam (yes, our animals do eat strange things, including lemon meringue pie). They are now the best of friends.
Simple DDS VFO project updated and software file uploaded. The pushbutton on the encoder is used to change step size (step sizes 10Hz, 1kHz and 10kHz).
Noise Canceller kits now available.
Updated both the DDS Xtal Substitute and DDS Xtal Substitute Mark 2 projects into one project. The original webpages are available to download as PDF's.
New project added - my version of the X-Phase noise canceller. PCB available and a kit of parts to follow soon

Another addition to the Gallery section. This time, fitting a DDS module to a Philips PM5326 RF Generator to cure a bad drift problem.
Here is a sheet I made up from the WIA's Australian band plan information, current as of August 2015. It only goes up to 70cm, as I don't have any gear that goes any higher than that.
PLEASE NOTE: Australian amateurs lost the 420 - 430MHz segment of 70cm's on 1st January 2013. This copy of the bandplan is now outdated, a newer version, by VK6DVR, subject to consent will be posted later.
