[Elecraft] K3 and ATT

[Nick Lekic]

Are the attenuator and preamp settings memorized between ant1/ant2 
and/or rx antenna ports?
For example , ATT is on and preamp is off on ant1 port but ATT is off 
and preamp is on when rx antenna port is selected.

On my current radio (non Elecraft), whenever switching between rx and tx 
antenna (while listening), each time one has to manually turn on / off 
the attenuator and preamp. 

The K3 block diagram indicates ATT attenuation is 10db.  Is it possible 
to increase/decrease attenuation level while operating?
