I know a car battery can be used to power the DX 394, but how does one
connect ? While the voltage would be correct, what about the current ?

If the radio is rated for 12 volts. Then there should be no problem. You
want a supply that provides the correct voltage and can provide at least
enough current. The radio only draws the current it needs.


OTH, if I simply took two 9 volt lantern batteries and hooked them up in
series, would that work alright, or would I need to reduce the voltage
with
a resistor ?

A good way to trash your radio. If you wish to use a source that provides
more voltage than the radio specifies, then you need to use a ragulator to
reduce the voltage to a proper level. A resistor only works if the current
demand is unchanging.

If using a resistor, if you draw too little current you get too much
voltage. If you draw too much current the voltage drops.

A radio may draw some current even when it is turned off to hold memory and
keep a clock running. (This may be very little) It draws some current when
on at low volumes. More current when the volume is turned up.

Two 6 volt lantern batteries might work better and be easier to find. In
series you would probably get enough voltage and lantern batteries can
provide the 1/2 amp the radio needs.

A manual should tell you how to hook it up.
