Node-RED is a visual programming language that is very powerful but surprisingly easy to use. The language has matured over recent years and has the potential to be a valuable tool for radio amateurs. In this talk, Mike will provide an introduction to Node-RED programming techniques. He will conclude with a live demonstration to show just how easy it can be to add extra facilities to your rig.

Receiving Antennas are Different
by Eric KL7AJ
Almost every ham radio station can benefit from a separate receiving antenna (or several!) While reciprocity applies to both receiving and transmitting antennas, the priorities are different. Effective receiving antennas are optimized for best signal to noise ratio, not necessarily the greatest gain. There are countless interesting means of building high signal to noise ratio receiving antennas and we will explore some of these in ‘Receiving Antennas are Different’.
