Rick, Definitely do not use a resistor. Its drop depends on current draw and if the rig is a transceiver it will draw much more current on TX than RX changing the drop.
You can use the lower battery, the one connected to ground. However, as some others suggested might be better to have a 24-to-12 V converter. 73, ron, n9ee/r >From: Rick & Charlotte <[EMAIL PROTECTED]> >Date: 2008/03/24 Mon PM 02:21:31 CDT >To: [email protected] >Subject: [Repeater-Builder] 24 vdc to 12vdc > >I hope some one on the group can help me out here > >I want to put a radio in a jeep > >the problem is the jeep runs 24 v and as you know radios run 12v > >Is there a device that will drop 24v down to 12 vdv ?
