Craig document his process of building a Better RTL-SDR TCXO with +-1ppm stability over 0C-55C range. Its hard to beat the cost and versatility of the ubiquitous RTL-SDR dongles, but the temperature stability of their reference oscillators isn’t sufficient for some applications. While the internal 28.8MHz quartz crystal in these units can be replaced by a high […]
