Running a radio from a large rechargeable cell or battery
If you are going to run a radio on 12 whatever bolts, (volts) forget the
inverters and use a Battery.Seeee,how simple life can be! cuhulin,the simple arse |

For good or ill, the easiest way to handle both issues is to go through an inverter, and, unfortunately, often a wall-wart.

Some of them cheap wall warts will Zapp out and Zapp (ruin) your gear
too.I have had it happen to me before. cuhulin |

THe RX340 has a funny DC requirement, or is their no DC input at all?
