[Elecraft] Operated K3 SSB in CW band - not sure why

[Richard Ferch]

VFO A is not always used for transmit. Whenever the radio is in Split 
mode, VFO B is used for transmit. If you found yourself transmitting 
using VFO B, Split must have been engaged somehow, either from the Split 
button or from the software.

VFO A is always used for the main receiver.

When Split is off, the transmitter uses VFO A, but when Split is on, the 
transmitter uses VFO B.

The subRX uses VFO B when Sub is in normal mode, but it uses VFO A when 
Sub is in Diversity mode.
