[Elecraft] XV-144 bandwidth

I have a question about setting up the K2 "RF" value in the menu
setting "trans2" for the XV-144. The K2 manual nor the XV manual state
anything about a specific setting. On initial power up the K2 freq readout
was indicating 38xxx.xx. I went in the "trans2" settings and set the "RF"
setting for 145, the center of the band. Is this correct? And after setting
the RF value, I still had to do a direct entry of 145000 to get the readout
on the K2 to indicate this frequency.
I am confused by all this. Can someone clue me in on the procedure
to set the RF value correctly? And do I need to go back through the
alignment again? I noticed that the power starts dropping off around 144200
at the low end, and 145500 at the top end of the band. Shouldn't I get full
out put across the bandwidth of the unit? I feel like I have set it up
improperly and am not getting best performance. I get full power out at the
center of the band, and I have it set back to 10 watts maximum out to drive
my old Mirage B1016 amplifier.
Also, as I tune toward the band edges, the gain seems to diminish as
indicated by a loss of noise from the speaker.
