Clicks are generated by rise times that are too fast combined with

Another point I forgot to make in this post is that many modern rigs
allow the user to adjust the keying rise time via a menu setting. In on

rise time was adjusted from slow to fast, and the default setting was
closer to awful than moderate. You can see these measurements in
