The FCC rules specifically required a maximum bandwidth of 2.6 KHz on the US 60 meter channels. That should provide a strong example of what FCC and NTIA consider to be the "maximum bandwidth necessary" for single sideband operation in amateur allocations. ---------------------- Absolutely right Joe! But "communications" is only one part of the purpose for the Amateur service. Amateur Radio is basically an experimenters medium and, the "Amateur" part means that the experimentation is not necessarily with a stated purpose. The purpose for putting a signal on the air is whatever interests the individual that falls within the rules. That's why the rules are very, very broad. The idea is to allow the greatest possible range of activities on the bands. 60 meters is *not* a "Ham Band". They are non-Amateur frequencies controlled by a whole different set of rules. Amateurs are allowed to use those frequencies only if they comply with those rules. That does not suggest that those rules should apply to the Amateur bands.
