[MRCA] MX-7777 and the mutt

[WA5CAB at cs.com]

As I wrote before, the 4-pin UW Series connector on the right or back side 
of the MX-7777(*) is not a signal connector.  Those have either 9 or 14 
smaller pins or sockets.  The MA/FA insert has at least (I still haven't looked 
it up) a 50 Amp rating at 24 VDC.  Comparable to that of the MS 3102E-22-2S 
3-contact connectors used on the output.

Also, the manual doesn't go into detail but it appears that the thermal 
switch, when it finally opens, disconnects the zener diode for about 2 minutes. 
 So if you hook a 45 volt supply to the system, it will only try to hold it 
down to 35 VDC for "a while"..  It wasn't intended for continuous operation 
under those circumstances.  Hopefully the supply overload would trip first.
