Cadenza: Learn Morse by ear
Operators do not read Morse, they hear it. Cadenza teaches it that way from the first minute: one character at a time, at full speed with wider gaps, until the rhythm arrives as a letter instead of a puzzle.

Editor's Corner
Hi, my name is Cale (K4HCK) and I'm the editor of Amateur Radio Weekly.
The most-clicked link from last week's newsletter was an article about an app that sends you notifications telling you how far away your CW message was received.
Speaking of apps, you may have noticed a new "Apps" section that consumed most of this week's newsletter. With the rise of tools like Claude Code, I'm seeing an absolute flood of Hams creating their own applications. This week I published all the apps from Hams that emailed me requesting to be featured in the newsletter. If this pace continues, or increases(!), it's going to be a challenge trying to highlight everyone's creation. We'll see if the onslaught continues next week. It might be an opportunity for someone to create Amateur Radio Applications Weekly.
General feedback regarding this newsletter or the content within is always welcome. Got a link to share? Simply hit reply.
