So is it legal to connect a phalanx of ham station ground rods to the
service entrance ground?? Or not.

As I understand it, according to the NEC, you must have only one
grounding *system* per building. This system may include two or more
ground rods, and/or a bare grounding wire buried in a trench around
the outside of the building. The ground rods and wires must be
securely bonded together with heavy-gauge wire... that's what ensures
that it's all one grounding "system".

Makes complete sense and answers my basic question. Thank you David.

I have five 8' ground rods already installed with more coming. All of
them will be bonded together with about 100' of #8 bare solid copper.

Let's try one mo This place is a "This Old House" type abode. There
is no basement and no visible service entrance ground rod. There's a
tight dirt crawl space under the place which I'm not about to even try
to wiggle and squirm through to find the power wiring ground
connection. If there is a ground it's the 3/4" copper water supply
line from the street which pops up somewhere in the crawl space per
normal practice in days of yore around here. I know for a fact that
it's an old ~80' 100% copper line, not plastic. On the other hand the
service entrance panel box is quite accessible. Would it be OK if I
connected my ham grounding system to the neutral/ground bus in the
panel box instead of to the water line??

It is not necessary to bring your bonding conductor to the inside of the
panel cabinet. Bonding it to the cabinet itself is sufficient. If any
portion of the Grounding Electrode Conductor is accessible then that is
the best place to connect your inter electrode bonding conductor.
