Yes, indeedy.

Multicast error, but no big deal. ntpq -p is reporting correctly on the
broadcast servers on my network. Also, I suppose I could have just
disabled chrony instead of removing it.
I had no idea about chrony and no idea it was installed *and activated*
by default. So much new stuff to learn in 7.
Thank you Frank and Gordon.
