If you like to modify you can make a VFO operate in just about any frequency range, but it will take a tedious time consuming if not miracle to make one track correctly across the band. Even if it is left stock and is connected to a 6Mc crystal radio that it was intended for, you can never trust what the dial indicates. Besides their inherent dial inaccuracy, they also drift. In any case, a frequency counter is essential with those IMO.
