[TenTec] Minimum Supply Voltage for Omni 6+

["Michael Tope" <W4EF@dellroy.com>]

I just received an Omni 6+ that I bought on Ebay. It appears 
to be working nominally, but the microprocessor flakes out 
if I drop the input voltage below +13 VDC (measured at the
power input connector with a Fluke 179). The manual claims
it should work down to +12.0V, and in fact my Paragon 585
works down to something like +10.5V before it flakes out. 
Is this a common/known problem with the Omni 6+, or is there 
perhaps a problem with this particular rig. I'd like to be able
to run it off a battery, but as it stands, I don't think I can. 

Thanks,

Mike, W4EF.............................................
