[TenTec] Minimum Supply Voltage for Omni 6+

Check the cleanliness of the 4 pin Molex power connector on the back, check 
the fuse holder and fuse, and check the connection inside specially the neg 
black wire from the Molex.  If any of these are loose or dirty then you may 
see some problems.  While you are in there, be sure all the connectors are 
properly seated and the MP chip and ROM chip on the processor board are well 
seated.  I have seen these problems with my rigs.

I've never really checked to see at what voltage the rig goes squirrelly.  I 
keep 13.5 volts on mine.  Same true for the Paragons.

Bob, K4TAX
