old cb radio question

[rbig]

Got a couple of older, but still quite nice radio's. They're the things that are hand held. They have 8 batteries, and rubber ducky antennas. Channel changers.

I have a power cord which plugs into 12vdc.

Big question is whether they are designed to run off of 12vdc straight into them, or whether or not they have to have batteries to work properly.

I'm starting to think both require batteries in place to operate.

I'd sure like to use on on a trip we're taking plugged into 12vdc. It would be very convenient NOT to have to put batteries into them.

Does anyone know the answer on these old radios?

They probably take 12 volts straight in but having a model number to reference would pretty much eliminate any uncertainties.

There is a very easy way to figure it out.....plug the 12v cord into the radio and see if it works.

I've done that. No workee. Thing is, there may be other factors at work, inside and outside the cases.

I'll post model nos later tonite. I'll take a measurement device and see if it's actually 12vdc getting to the radios.

I think I may have found the problem. I took a VOM out to the car this evening. It's not getting 12vdc at the plug end of the extension.

Did basic troubleshooting. The thing that plugs into a cigarette lighter had a blown fuse. I suspect tomorrow when I replace that, we'll have these things working right.

Here's the model nos:

a. Cobra HH35

b. GE 3-5980A

They work fine without batteries!!!

I got the fuse in the plug, and has one more blow on me. Reversal of polity on the gadget that plugs into the end of it. Got that one turned right, and BINGO: good results!
