A while back I thought it would be useful to be able to limit a VFO's frequency excurusion to a user-selected segment. Then if you should get to the end of such a defined segment the VFO reading would simply jump to the other end of the segment and keep going, traversing the same segment again as you kept spinning the knob.
I didn't think of this as a method of marking the legal band boundaries, but rather for the purpose of sorting through a pileup without having to keep looking at the frequency display, reversing VFO direction, etc. Just keep spinning the knob and you'd always be within your defined segment. BTW, I don't work any pileups myself; just like to hunt through them to find who/where the DX is currently working (no sub rcver or band scope here). But I suppose those who generate the pileups might find it useful as well. It could of couse also be used to limit the VFO excursions to the legal band boundaries if someone wanted to do that. 73, Drew AF2Z On Tue, 20 Aug 2013 13:30:48 -0500, Terry, W0FM wrote: >My needs are much simpler than those involving international frequency tables, >license classes, memory locations, etc. I haven't thought this through >thoroughly so I don't know all the ramifications.
