#267 In this video I look at one of the activities that involves both radio, the weather and faxes. While its relevance has decreased in recent years, receiving weather charts over fax is still a reliable backup solution when all else fails. Its also a nice way of testing out SDR and decoding software.

![Timeless ICs - Linear Regulators
#255 In this video I look at some of the oldest ICs that are still in use and production today. These are not the best in their class but they are well known and easily accessible. Most of these components are a common site both in older and newer devices and well suited for their job.
