Re: [Amps] Centurion cooling improvement ideas for AM service

[Bill Fuqua <wlfuqu00@uky.edu>]

Actually I said 5 KHz audio bandwidth which is 10Khz RF bandwidth.
But I am surprised no one read the rest of my email. I expected to get some
responses to the issue about CW bandwidth. And I concluded that it is best
not to mess with the rules and trying to be too specific. If we get into a 
mode of
trying to spell every thing out precisely it will the rules will degenerate 
to something
like those for 60meters.
