[BC] Crown rack-mount transmitters

[Mulford, David]

Cowboy -  Thanks for the earlier reply.

We're looking at moving our LPFM's Crown Xmitter to a local water tower next
year - which has a pretty substantial cell site, and some UHF/VHF public
service facilities.  This is all in the "might happen" stage, depending on
our local municipality folks.

Since you've noticed these Crown transmitters like to mix like a KitchenAid,
and blend like a Waring - who would be the best person to contact for help
in obtaining a correctly tuned circulator?  You mention Junior, but since
I'm not a FT engineer (and don't pretend to be one) I'm at a bit of a loss
in this area - and at least 60 db down in knowledge too :)

Any thoughts/advice would be most humbly appreciated.
