July 2025 UR5WHK has created an updated version of the AD9833 project which now includes a MAX7219 based LED display. You can find it under the Gallery menu.
March 2025 In something of a "Seniors Moment", I forgot to update the homebrew menu and this section relating to a project I did late 2024. That project is an update of one from the RSGB Radcom magazine of Sept 1999 - 'Turn Your Dip Meter into a Signal Generator'. Presented here as 'Grid Dip Meter (GDO) Add on' under the Homebrew menu.
November 2024 Phillipe F6ETI has done some serious testing on the Noise Canceller and shown it works up to 72MHz and is usable with some loss at 145MHz. Links to his website with photo's, video's and description of the testing on the Noise Canceller page.
Privacy Policy uploaded. 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. 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.)
This project has been superceded by the updated DDS Xtal Substitute - 2017 project.
