The first episode of what's promoted as a regular video presentation includes West Coast AMer
Joe Walsh, WB6ACU.
There's some discussion of AM before they get into the more ordinary, boring parts of the hobby, but it's worth a watch.
Not sure whether subsequent episodes will continue some coverage of AM, but we shall see.
This initial production does not include any on-air recordings, just internet-based video and audio, but it's a good start.
