[Elecraft] [K3] Minor XIT/RIT display glitch with band change byRS232

[Joe Subich, W4TV]

Snooping on N1MM Logger and the K3, N1MM Logger does not 
issue any command to directly turn off RIT when changing 
bands (Ctrl-PgUp/Ctrl-PgDn).  Using the Ctrl-pg commands 
results in only one FA; or FB; command based on the last 
used frequency on the next band.  

It appears as if the K3 is not heeding the SPLT SV setting 
(for RIT ad XIT only) if the band changes in response to an 
FA; or FB; command. I can  duplicate the behavior using a 
terminal program equivalent to the Command Tester in the 
K3 Utility. 

Further, when the band changes one time, the RIT/XIT offset 
is retained, a second band change will clear the offset. 

73,
