Tom: You are absolutely correct, and I was not suggesting its OK to operate
with emissions outside the phone band. I was just trying to address Tõnno's
question as to why the ITU R1 band plan specified dial freq for LSB
emissions on lower phone band limits and did not do so for upper band
limits (on 20 meters and up), which may include  modes other than USB.
