Frank, K4FMH, is one of my fellow “presenters” on the ICQPodcast. He is also Professor Emeritus at Mississippi State University, where he taught statistics, survey research methods, and GIS/Remote Sensing over four decades. In other words, he’s a pretty smart guy.

His latest effort is a study that compares a list of popular HF transceivers and receivers sold in the last 50 years by these three criteria:

• retail price

• measured receive performance by Rob Sherwood NC0B

• overall satisfaction as reported in the reviews on eHam.Net.

A couple of days ago, someone posted the article, “A novel way to hear weak CW signals” (CQ, January 2018) to the Long Island CW Club mailing list.

In the article, the author, Pete,, N8PR (SK) writes that you should set up your receiver to produce two tones 65 to 80 Hz apart to make copying weak CW signals more easily. The theory behind this is that the dissonance between the two tones makes copying a CW signal more copyable than just a single tone. I like this idea. I played around a little bit last night with this technique, and it did indeed seem to work better than using just a single tone.
