[Elecraft] USB on all bands ??

[K9ZTV]

In reply to a similar question at Dayton, Riley Hollingsworth 
specifically addressed the legitimacy of hams using LSB on 20 meters and 
above, and  USB on 40 meters and below ("with the possible exception of 
160 meters" which drew a laugh from the crowd).  The convention 
currently in use is merely traditional and reflects military preference 
for standardization (due to channelization) promulgated in the early 
days of SSB.
