[Elecraft] asking for operation tips - KRX3

[Johnny Siu]

Hello Group,
 
I got my KRX3 when I was in Dayton.  I now have my 20m antenna as ANT1 and 6m antenna as ANT2.  While working in 20m, I would turn on 'SUB' to monitor the DX window of 6m at 50.110Mhz.
 
Now comes the question.  If I notice a DX call in 6m in the 'SUB', how I can quickly switch the 'SUB' to main band and TX in 6m right the way answering the CQ call.  I tried to push 'REV' but I was not allowed to do the 'switching'.  Do I miss anything?
 
Apart from listening 20m on one ear and 6m on the other ear, is there a way to monitor the S meter reading of both 20m and 6m simultaneously?  Forgive me in asking these questions because I could be used to the operation convenience in my IC7800.  Anyway, I need this K3 for portable use before KX3 is available.

TNX & 73,
