[MRCA] M151 DC Distribution

[WA5CAB at cs.com]

I'm sure that you're correct about early installations but installation of 
the MX-7777/GRC is not limited to armored vehicles.  I've had people report 
having it in M37's, M38's.  It wasn't the vehicle that determined whether 
you got one or not.  It was the radio.  Vehicles equipped with AN.GRC-3...8, 
etc. don't need it.  All the solid state stuff does.  They can't hack the 
transient spikes generated by the starter motor.  The T-195B might need it.
