Just for info ....... There are NO rules in part 97 regarding bandwidth in any phone mode. You can run whatever width you want. Just as long as it falls under "good amateur practice" which can be interpreted in my ways..... I interpreted it as 3khz to 4 khz for SSB.........As my MP runs a SSB Bandwidth of 3.3khz in the analog mode thanks to Art Collins filters !! Please read part 97.307 & 97.307a 73's john
