In addition, you will need to consider the length added to the stub by
the switching circuitry, also the optimum location of each stub along
the feedline, which is VERY important.

You might find that investing $50 in a NanoVNA would be useful. It
would let you make "thru" measurements for the system, for instance, as
opposed to just cutting stubs, etc.
I have seen comments over several articles about making different length
sets for CW vs. SSB contests. What target frequencies should I be cutting
each of the stubs to using my RigExpert analyzer for SSB? What would I
use
for a second set for CW contests?
