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.
Updated Australian Band Plan page with the latest info (under 'Misc' heading).
A modification plus software to allow the Simple DDS VFO to be re-calibrated as often as you want without having to re-program the PIC has been added to the Simple DDS VFO page. Simple DDS VFO bug problem fixed. Code uploaded to webpage as version 'c'.
There is a bug in the Simple DDS VFO code. See Simple DDS VFO page for the problem and updated code. Included an add-on for the Simple VFO project to indicate which step size has been selected. 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
There has been an increase in the activity of those mindless dweebs sending out spam and other nasty things, so rather than remove this contact page, IP blocking has now been implemented. Other measures have also been implemented and more is to follow. So, if one day, you find you cannot access my site then an address in your IP range is a spam generator/mindless, snotty nosed idiot. Complain to your internet service provider, make them stop the spam and have your IP address range unblocked.
Normally, you should receive a reply from me within 48hrs. If you haven't, please check your SPAM folder first just in case my reply ended up there. Otherwise, please try contacting me via my email address which is good on QRZ.com or by 'my callsign' at 'this website address (minus the www)'.
