The program says this coil is resonant (?) at 10.120 mhz

Now here comes the really dumb question - will this cause
a problem on 30 meters? I seem to hear OK but I've not
yet tried to make any contacts...

My SWR meter indicates a 3:1 SWR there but my nifty
Z11 autotuner tunes it just fine.......

What am I not understanding here?

Hi Ken,

Not much reactance overall for one. I've lost track what bands you
want to work, but the SWR would suggest not much Q either. There is
also the matter of how long your cable is too at any particular
wavelength; at some lengths, like half wave, it just doesn't matter if
you had a choke or not (the radiation resistance would snub the
current anyway).

You got 3:1 for any number of reasons, but your tuner took care of it.
That's what a tuner is for. [However, as a solution it is unrelated
to your original problem of a hot coax shield.]

Feeling a little chagrined at accelerating the super glue bond? ;-)

Offhand I would offer that you are probably out of the woods. Just
leave it alone barring repeated symptoms that lead you here.
