Solar Cycles – Enjoy those Sunspots
I was surprised to see tons of signals on the 15 meter ham band this weekend. Solar cycles effect how well radio signals propagate, and latest cycle has not been very good. Read more
AM Radio Signals – Day and Night
There are over 100 channels in the AM broadcast band. During the day, you can hear signals on only a few of these channels. At night, you can hear signals on almost all of them. Why?
HF Radio Propagation – Tools You Can Use
HF radio propagation is the science and art of understanding how and when shortwave radio signals travel from a transmitter to a receiver. Beyond a short distance, shortwave radio signals travel by bounding off layers in the ionosphere. Often, there are several bounces. Here’s how to figure out how and when you can expect a signal to arrive at your location.
