<DIV>I called you on your 14 machine and got no reply. I noticed that I could
hear myself unkeying (but not speaking) but that does not dissuade us from
wanting (needing) a voted system. Our Inland Empire machine can be heard just
fine all over So. Calif. but Rose Hills blocks us to the west since moving up to
Heap’s Peak. Even on the 210/134 corridor out to Santa Monica but limited RX.
Our vendor has a PV site and we’ve thought of a multi-site simulcast system. But
as you know Tim, here in So. Calif. there is significant overlap. That means a
centrally located TX site like you have. That will cost us $350/mo. just for
site rental. But that gives us an intranet if that’s what we want. If going the
simulcast route we’d elect to use Oat, Heap’s and Quartzite but they all overlap
significantly. I wonder if anyone has thoughts on tis that they might
share.</DIV>

<P class=MsoNormal>It works, but not perfectly. If you have minimal overlap,
it's acceptable, but once your coverage starts to overlap, it gets hairy.
Typical of any simulcast system to a certain extent, but perhaps a little
worse than others. <BR><BR>There is a high-level system that used to simulcast
from two big mountain tops using RTCMs (BIG overlap) and it was really
rough whenever you were in earshot of both transmitters. <U></U><U></U></P>
