[Elecraft] 50MHz Transverter

[Phil Theis]

Given the following setup: K3 using transverters, with 50MHz transverter 
set for xv1.
When I enter a 50MHz frequency via the com port the built in 50MHz 
receiver is selected.  I then have to band up once to get to the xv1, 
then I can successfully band up to 144 etc.  If I enter a 144 frequency, 
it immediately goes to xv2.
What would it take to get a serial command to go to a frequency in 50MHz 
range to go directly to the xv1 selection?
thanks
