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.
