Suppressed carrier (dial frequency) should be at least 3kHz away from the 
SSB band edge.  On 20m USB that would be 14.347

Subject: [CQ-Contest] band plan definition - LSB vs USB

There is one thing has been bothering me for a while and I am sure there
are some knowledgable people here who can explain this.

ITU R1 band plan says:

* - Lowest dial setting for LSB Voice mode: 1843, 3603 and 7053 kHz*

But it does not mention the highest dial setting for USB on 20-10 meters.

So is it allowed to work USB on 14349 what concerns the band plan?

IARU Region 1 and Region 2 band plans both also say:

*Transmitting frequencies: The announced frequencies in the band plan are
understood as “transmitted frequencies” and not those of the suppressed

What does it mean? Does it mean that furthermore, it is stressed that 14349
is OK as it is the transmitted frequency?
