[Elecraft] K3s SSB transmitting bandwidth?

[Andy Durbin]

"This is good data for those running sound card modes such as FT8."

If you do FT8 right you only need a TX bandwidth of 500 Hz (low 1,500 high 2000).  Any more than that is only needed for those who insist on not using split and more than a few of those are over-modulating and filling the spectrum with double wide and triple wide audio harmonics.
