CI-V simplified by modern tech for Icom radio control

There’s a simple eighth inch jack on the back of most Icom radios that provides a communication interface for control purposes. If you look around for how to tie this into a computer, most of what you’ll find is about converting to a standard RS-232 serial port. That is soooo old tech! I like what Guy […]

Doing that is a can of worms. The current most common method […]

NTP via GPS on an ESP8266 using MicroPython: design issues

It’s been done before, lots of times. Sort of. But maybe not just this way. The collection of parts and pieces provides for a broad curriculum of learning possibilities. Here are some of the issues that have come up so far. SNTP vs NTP. NTP has a long history and it is intended for always […]
