By the way, I have plenty of Allen Avionics delay bricks.  These were
installed in the original Quintron Simulcast systems.  They work well if you
know how to hook them up correctly.  1105 max delay which equates to about
204.6 miles of delay, but what do I know?

I believe the MN chips are now out of regular production.

Traditional analog microwave simulcasts are a pain
to do on some systems. You need to deal with both
group delay and timing issues for both the audio
and any sub-tone/dcs requirements. An E1 or T1 would
be easier.

Cheers Bradley,

ps: Are not all the microwave systems on your side of
the world upside down?  :-)
