(Best is still based on propagation and is a topic for another blog). My HF station is in Arizona,… Continue reading Remote control of SDRuno with MQTT and Node-RED

Everything has been… Continue reading Noisy computers?

They also send a lot of short messages that anyone can receive and to some extent decode and make some sense of. This has been keeping me busy for… Continue reading ACARS
