I  almost have that situation on 160m when I use my 80m dipole, fed with 
open wire line and balanced tuner.  I can move maybe +/- 5 kHz before I have 
to retune.  Using that antenna set-up is like being crystal controlled, 
since I have to go down to the tower to re-set the tuner.

Hopefully, by upcoming season I'll have my remote tuning system, with 
reversible DC motor, so I'll at least be able to QSY within the same band 
without a trip to t he tower.  I hope to eventually make it so I can change 
bands remotely as well.
