[Elecraft] K3 selectivity display?

[Jeff Stai]

hi Craig - three things:

1. The manual advises you to order the filters from widest in XFIL 1 and go narrower from there. I 
think this is good advise, to keep it easy to remember where they are. You can order them any way 
you want, this is just a recommendation.

2. I don't think you will move filters very often. It is a lot of screws to remove since both the 
bottom and top covers have to come off. I think 95% of the time you are just adding a new one into 
an empty slot.

3. I understood that additional filters are planned, including variable filters, which would further 
complicate the display if not using the XFIL notation.

hope this helps! - jeff wk6i
