        Amen to that! I'm not an engineer (not at all), but various things
I've seen and heard over the years have convinced me that many AM stations
have lost a lot of signal from their ground systems deteriorating with age
and nothing or not much being done.  I have a theory that WEEI /850 has
this problem. And now, with AMs relegated to secondary status by most
owners, even less $$ is being invested.
        I was told last year that the engineers at WHYN AM & FM in
Springfield have been trying to get a new ground system put in, but
whatever money is being spent on engineering improvements these days is
going to try to fix the FM's weak spots down among the high-rise buildings
in downtown Springfield.
        On the other side, a story I like about this question is from WICC
in Bridgeport. I once was told that the CE in the early '70s convinced
management to spend what was considered a lot of money to completely redo
the ground system (two towers). When it was about ready to go, he worried
that he may have over-promised how much better the signal would be. When it
went on the air, he was amazed at what a difference it made. It far
exceeded what he thought it would do. The bosses were happy and WICC still
has a great signal, although maybe it's time to order some new copper by
now <g>.
