DC Power Distribution:
 Not all shacks run DC exclusively. Some have no DC at all,some are totally
DC,but most are partial DC power.
 Many hams have rigs that are meant for mobile use and are used as base 
nits.
 Many HF rigs run on DC only and the additional cost of a power supply is not
within the wallet of most. They resort to batteries and chargers.
 Some enjoy the advantage of power on request from a battery bank,powered by
a large power supply and several batteries. No commercial power,no problem.
 Others prefer commercial supplies or many commercial supplies; one for each
radio. Some even enjoy the use of an Uninterupted Power Supply (UPS).
 Regardless of what you use,there are some DC distribution ideas I would like
to convey to the readers.

DC POWER PANEL
 You may have to either distribute your DC power from one source or recharge
your several DC sources from one commercial source or combination of the two.
 Here's an example of a simple DC power panel in use here:
All rigs are DC powered;
o Ten-Tec Closet Kilowatt
o Kenwood TS-430S
o Kenwood TR-751A
o Kenwood TM-421A
 The battery bank consists of four deep cycle batteries rated at 115 AH each.
 Power supply is a Pyramid Phase II 50A.

        TS-430S______| |
                       |
        TM-421A________|
 The power and ground bus run like this to the power supply:
    ground bus-------------------------P/S ground
    *Batt 1--------SW1-----------------|---P/S positive
    *Batt 2--------SW2-----------------|
    *Batt 3--------SW3-----------------|
    *Batt 4--------SW4-----------------|
 It's farly simple system that allows the rigs to be operated with or
without charging in line.
