[TrunkCom] strange sounding Motorola control channel on Detroit Transportation's system

[JEFFREY MICHAEL KENYON]

Good morning everyone.  I've been hearing the new control channel for the
Detroit Transportation's system on 452 MHz, and it sounds more like an
Astro Control channel, then a regular 3600 BAUD control channel.  I'm just
wondering if anyone has tried to trunktrack it or not?  The channel isn't
quite sounding like Astro, but it isn't 3600 BAUD either.  Any information
would be appreciated, and thanks in advance.
