Cobra 2000 GTL

[kingcraig1991]

Does anyone know what size size the cobra 2000 gtl uses? It says 250A 4V but it appears they come in different lengths. Can anyone help? Always wanted to get into CB and recently inherited a bunch of vintage radios.

lol You mean 250V 4Amp. Its 1 1/4 inch long. A standard fuse.

That might be for a DC power fuse but not for the AC side, that would be an amp at the most.

 

[rcarl]

It would be in the rear panel.

Here's the the thing. The radio powers on. All lights and nobs work. The only thing is there is no sound. I know the speakers work because I tested them on another radio. Could that fuse be the problem? It probably hasn't been changed in 20+ years. I appreciate all of your replies. Excited to get into cb

It could be as simple as not having a working microphone connected. That is how I bought my most recent Cobra 2000 GTL. Everything appeared to work, but no audio, and people walked away not knowing that a mic needed to be connected. I knew that I could use a pocket knife to short the mic connectors to test TX/RX and audio. Bought the radio cheap, and then bought a five to four pin Cobra compatible adapter, as I had several four pin mics for Cobra 29 LTD Classic mobiles. Plug in the adapter, a known good working mic, and audio works fine.

With the Cobra 2000 GTL, it also has a selector switch for 1,2, or both speakers, while only usually shipping with one speaker.

I tried 2 different golden eagle mics and nothing. The signal meter doesn't move. Shouldn't it to indicate I'm a receiving?

Your radio needs surgery...

Have you tried An external antenna ?
My next door neighbor had this issue where the antenna cable was not good but he could hear me on the air
so he assumed the antenna was good.

Just because the microphone plugs in does not mean its wired for the Cobra 2000.
As with my Cobra 148 it needs the RX pin grounded on the microphone to work.
This is done through the switch in the microphone.



The inline fuse Is a protective circuit feeding the Voltage and current - Seeing the radio turns on its not the fuse.

I checked the mic. It should be compatible. Changed the battery in the mic. I'm using a cheap magnetic cb antenna. So heres my next question. Do I take it to a repair shop? Or just sell it as is on eBay and buy a new base station with a decent antenna? I don't want to put alot of money into the radio.

I owned one many years ago. Had a guy add the extra channels. Awesome radio. I envy you.

What's your Budget?
A CB shop - Depends where you live and how much an hour they charge and that's if you can find one.
That and or you find an Elmore that has some CB or Ham technical skills.
Selling a Dead Duck on Ebay Is a no win Scenario !

Don't Beat yourself up for a Hobby - Start small and see if you have any interest.

If you are thinking in the "buy new" train of thought it may be a good idea to wait a short time and see what the new FM allocation does with the manufacturers. I don't think FM is going to cause a 1970's style resurgence for CB but I do think there is going to be a number of new models on the market, possibly even base station type units. Currently there is only one "base station" model and it is hard to find in stock. It is going to be interesting to see how this pans out.
