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 even be replaced with one of many commercially available TCXOs!
