News, Updates and Other Minutiae
August 2019
Website outage - I made some hosting changes and there was a minor hiccup. Hopefully everything is now back to normal but please let me know if anything is missing.
The start of a new project added in the Homebrew category. Specifically, a Frequency Dependant Switch. Measures the incoming frequency and switches 1 of 8 outputs on. Software for this project uploaded.
June 2019
Added another project for the AD9850 DDS modules. A Simple DDS sweeper in the Homebrew section. This is an absolutely basic, no frills project using a 12F1840 to sweep a DDS module between a range of frequencies. Plenty of scope for you to improve on the software and add extra features.

Custom code/webhost costs
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 few of years and shows no signs of getting any cheaper.
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.
GPDR and all that stuff
In accordance with various bits of legislation around the world, either currently in force, about to come into force or proposed, you will now find that annoying "We use cookies" notice at the top of this website. Please note that the ONLY cookies currently used on this site are for that pop-up (see https://cookieconsent.insites.com/) and Google Analytics. The full Privacy Policy is available at the Privacy Policy link in the footer at the bottom of the page. (If you don't know what GPDR is, Google it. Real scary shit for ANYBODY with a web presence.)
F1ITU Simple DDS VFO Mods
Daniel F5ITU:- "I just finished the adaptation of your software to "Simple DDS VFO" for my personal use. It works well and I will soon install it on my "DC receiver". So, now I have a VFO (10Hz step) and which performs a 600 Hz shift when it receives a transmission command on GPIO-3. In addition, I added to the printed circuit, an amp to increase the output level so I can get the necessary 7dBm the SLB-1 RX."
Daniel kindly sent these images of the changes to the code, along with his actual ASM file as well as his Sprint layout file for his pcb. You can find them at the end of the page. Because the following images may be a little hard to read, I have put them in a zip file you can download, also at the bottom of the page.
