For what it's worth, I do not believe the the radio is now working
perfectly - although given a specific length of coax, it is much improved.
This is proof that the resonance of the antenna system is dependent upon the
length of coax feed - which is a sign that the antenna is not ideal in
either site or design. If it were, the length of feedline would be
inconsequential.
This does not mean to imply further investigation. It simple means
the cripple now has a proper length artificial limb. I would not disturb the
touchy balance. However a small corrosion, or motion in a connector or
whatever will eventually disturb the ideal, and then it will give rise to
some research into the fault. Penny in the fusebox.
