Do you trust that RF sensing function?  REALLY trust it?  Because if you 
transmit
into the wrong LPF, it can be Game Over for the PA transistors.  I went 
through
three sets of expensive LDMOS devices on my Medium Linear project before 
I bit the bullet
and hooked up the band data from my FTDX10.

With the band data hooked up, the linear is always set to the correct 
band.  Even before
you transmit.
