Dan Watson has published a new build: There are some good, inexpensive TCXO modules on eBay that come in the slightly unusual package shown above. This breakout board allows you to mount one of the modules onto the small PCB and adapt it to standard 0.1″ breadboard-compatible headers. I have also included a few optional […]

Building a better RTL-SDR TCXO
Craig posted an article describing how he built a 28.8MHz RTL-SDR TCXO, that is available on github: Here’s a scratch-built 28.8MHz TCXO capable of +-1ppm stability from 0C-55C; best of all, it’s not only easy to build, but is designed entirely from readily available and inexpensive components. For improved temperature stability, the main oscillator can […]
DS3232 clock frequency calibration
Kerry Wong writes: DS3232 is an extremely accurate RTC with a guaranteed accuracy of 2.5 ppm (0 °C to 40 °C), which translates into an error of just 80 seconds over the course of a year under the worst case scenario. I had done a few projects using this chip before (you can read about […]
