The B/C committee of Region 2 was chartered with developing the revised
Region 2 band plan based on the structure and fill of the existing Region
1 band plan with "regional and frequency" differences taken into
account". Since the voluntary Region 1 band plan has been in existence
since January 2006, what rules are the amateurs in these countries
covered by Region 1 following. We know that a number of U. S. amateurs
have worked European stations on 75 over the last several months. Are the
European amateurs actually limiting their AM bandwidth to 2700 Hz.
