I've noticed that there isn't much activity on my local repeater. Perhaps I'm just not listening at the right times, but I've sampled the repeater throughout the day on different days of the week, and aside from some scheduled net activity, users seem to be maintaining "radio silence"!
Are you wondering what ham radio (Amateur Radio) is all about? The ARRL website has plenty of good resources for you, including some videos. If you have a disability, come back here to handiham.org to learn how the Courage Kenny handiham program can help you get your license.
