[Elecraft] Frequency Limits by license?

[Vic Rosenthal 4X6GP/K2VCO]

It wouldn't be a good idea to depend on the transceiver. If you are 
operating USB, for example, you have to keep the (suppressed) carrier 
frequency several kHz below the top of the band so your sideband will be 
inside it; same for LSB and the bottom of the band. Even in CW there is 
a consideration of bandwidth, although the K3 series rigs have very 
narrow CW signals. But it would not be prudent to operate exactly on the 
band edge.
