[BC] Crown rack-mount transmitters

[patrick roberts]

I just called EMR.  They are having some issues with production of
their 250 watt units.  If they were still available, they'd run around
$1290.  Speaking with Crown, they gave me a guesstimate that the
"G-unit" with that 90 degree isolation cancellation thing would be
about 700 bucks or so more than normal units.  It offers a reduction
around 30-40db, which of course isn't perfect, but might do the trick.
 He'd have to check around to see about parts to build one as they
haven't in a while.

Just thought I'd pass on what I've found out...
