How do you test an ANALOG RF meter?

A battery itself is a good way to make sure the meter is blown.

Use a DVM set on the DC 1 mA range across the meter. If you read nothing, then something else is dead/broken inside the radio.

You can use the battery only once. It will probably slam the pointer over to the end and ruin the meter. Most likely the meter will only have a full scale of 1 miliamp or even less.

Try hooking a digital meter in the voltage or miliamp range across the meter to see if it shows anything. YOu may be able to disconnect one wire going to the meter and measuring it with the digital meter set to ohms. Just tap the leads to see if the meter moves and it may move the wrong way.

I did what you said. I do get a reading on the DVM. So the meter on the radio is blown. Ebay has lots of them for $10 or less. So I'll replace it. Aside from this meter and one bad segment on the channel selector, the radio receives and transmits well. Now, if only I could find someone on the CB to talk to....... This radio also has the weather band, so that will come in handy in my car. I always like to keep track of the weather, and I dont use a smartphone. My old flip phone is all I'll ever need.

By the way, this Cobra 29 was made in 1995, so its one of their "newer" radios.

Aside from the fact that hardly no one uses the CB anymore, I was at a truck stop last week, near a big city. I was surprised to see how much CB gear is still being sold there. Apparently the big cities still have CB traffic. Probably mostly truckers. But it sure aint what it was in the 70s.

Thank God.

Confusing post. Are you referring to the physical moving hand meter itself, or are you referring to the whole box?

If the meter shows the full scale sensitivity somewhere on the face, you can compute the resistance necessary to put in series with a 1.5 volt battery and correctly apply the + and - to the meter movement and see if it moves.

Alternately, put a 10k ohm resistor in series with your Ohmmeter leads and test the combined resistance to see if you get 10k Ohms. If so, then the meter is ok.

Since we are commenting on CB use. I too am glad all the kids and idiots are gone on the CB Band. These days they're all on facebook instead. I do tend to not understand what happened to all the truckers on the CB? Channel 9 is really no longer needed. For emergencies, people can just use their cellphone to call for help now. But truckers cant get instant road conditions up ahead, or smokey reports on their phones. And you cant talk to other truckers near you (unless you know all of them and have their phone numbers). So for truckers or anyone on the road, the CB still has a lot to offer. Not to mention its against the law to use a cellphone while driving in many places now. But not the CB.

Two things I hope to never hear on the CB again are those annoying Roger Beeps, and the echo mics. Neither served any purpose and just made the CB hard to hear or worse.

One other benefit of CB was that a lot of times in the past, I'd just talk on the CB to keep myself awake while driving late at night. And I had a lot of interesting conversations, as well as finding out where the truck stops are, where to get a good meal, and learning interesting facts about the area I'm driving in.

I miss the good old days of CB. But not it's later days that partially caused it's demise due to abuse. Then too, the internet has been on a similar downward spiral. The early internet was both fun and useful. These days its been taken over by that repulsive Facebook and if you want anything useful, such as a repair manual, be prepared to give away your identity to some crooks, and pull out your credit card. Or just waste hours sorting thru all the bogus claims that say "FREE" manual or whatever.
