Tonno, I think the difference lies in the fact that the LSB settings on 
1843, 3603, and 7053 might place you at the lower bounds of a preferred 
frequency range, but operating below that does not endanger your 
license.  By contrast, operating on 14349 USB means your signal is 
guaranteed to bleed above 14350.  No need to remind you about plans 
there because operating there violates your license.
