You can use a SDR Online to monitor your signal. You will see how your real signal looks like.

The ‘101D spectrum scope is useless for determining TX bandwidth. So are 50% of reports given on the air :)

 Been there and done that.  After lots of adjusting those settings, looking at graphs on Audacity,  audio quality reports from others,  and if other people can’t see it any splatter or signal on both sides during SSB Tx, then I don’t care.

If you see your signal at both sides during USB/LSB then you need to adjust your mic gain, AMC and PROC.

I, too, was very surprised to see my signal on Tx.  It looks like I'm splattering all over the place, not staying "on my side" of the carrier in SSB.  However, other stations have confirmed that my signal is clean as can be :)
