Recently on the bands I have had or heard several QSOs with stations giving a report of 'Radio 3.4 or 5'. I personally received a Radio 3 so must assume that my signal was 'classical' as this is the name of a classical music broadcast station in the UK.
I thought that the licensing exams covered reporting protocols so no idea how this corruption of Readability report (if this is what it is) has appeared. What happened to learning from others?
I have a link on my website which may throw some light on this: http://www.hamuniverse.com/rst.html.
