ESSB Audio


There seems to be much controversy regarding eSSB audio, what is legal verses illegal to run bandwidth wise here in the U.S.

eSSB Audio has had its share of drive by comments some good and some who have gone off the deep end ranting that it is illegal, bad amateur operating practice and that the audio is distorting and splattering.

To those uneducated or have been misinformed by those who are set in their way and opposed to anything new. This has been settled before I would suggest you get educated before you make a fool of yourself and spread more bogus and misinformed information. I'll simply point you to the following which is of public record and can be found on the FCC website:

Scroll down through the list until you reach WTB Order (DA 04-3661)


WTB Orders (DA 04-3661)

Rulemaking under Part 97 of the Communications Act of 1934, as amended to Establish Technical Standards for Certain AmateurRadio Telephony Transmissions

Denied the Petition for Rulemaking

Reading through the petition which was filed November 24 2004 you will find that eSSB is not an illegal mode and can be run when observing good amateur radio practices. A group on 80 meters has been singled out by many a drive by and those who simply are uneducated, or don’t understand good amateur radio practices. Many of us down on the lower end of 80 meters run eSSB with bandwidth of 3K + and have for some time, However there are some individuals who simply want to stir up trouble because they either don't  like it, have been misinformed, or simply uneducated regarding the FCC ruling:

Don’t move yourself in our pass-band then come up and start complaining that we are splattering and distorting down where are you, that simply is not the case at all. The problem here is you have placed yourself within our TX bandwidth. So the proper solution to this is, if you want to talk about good amateur operating practices, you should listen a few minutes where you intend to be transmitting, If you hear what you call splatter or distortion, move up or down a few and see where it is coming from if its someone or a group running eSSB who happens to have been in there before you started your QSO or calling CQ then it is up to you to move out of the bandwidth or pass-band of those operators.

If there are QSO's near or within the bandwidth we intend to run we QSY or narrow up some so that we don’t cause intentional interference, however the same can’t be said if you move in our pass-band and cause interference to our QSO's-

Use some common sense, get educated and don’t mislead others stay out of the pass-band or TX bandwidth that is in use and everyone will be happy!

Those that think that 2.7 or 2.8 is the limit of allowed bandwidth, I ask why then our more and more transceivers allowing the option of running more TX bandwidths, If the bandwidth was fixed at a maximum 2.8 and the rig was capable of more, how did it pass the acceptance certifications?

Regarding the distortion or splattering audio much of this is due to your receiver operating in a narrow bandwidth you are simply not getting the full audio that is taken place which comes across as muddy or distorted sounding. There are plenty of modes that appeal or don't appeal to individual operators, If you simply don't like eSSB that is your choice but don't jump in and accuse those who do of illegal operating or intentional splattering..
