Keep it for parts, keep it for what ever - even if you just keep the microphone.

This is called a life's lesson.

People do not usually get rid of a good working CB radio unless it is JUNK!

A indoor antenna is not going to work properly.

It needs to be a certain segment of a wavelenght in size 1/4 - 5/8 ths and it needs to be at least 30' off the ground...

If your antenna system was ok - and the SWR of the antenna was ok, I would suspect the radio was faulty.

Unless you have another transceiver to check the antenna - the SWR meter is not going to do you any good.

I highly doubt if it is going to be as simple as just using an OHM meter and a soldering iron to repair - especially since you have no electronic's background.

You can check the TX if you have another microphone.

Some CB's will not receive unless there is a microphone attached.
There is no way for me to know if it is the microphone or the transceiver until you find a microphone that actually works.

If you knew of someone who had a electronic's background, you could check the final transistors and replace them...
Probably - the person who you bought it off of had it connected to a crappy antenna and it fried the finals....

Sometimes you can start at the front end and work your way back - but it is going to cost you more to fix it yourself then what it is worth.

A CB shop will probably charge you $65 to repair it - not worth the bother, when you can buy a brand new one at Pilot for about $89.00 with a warranty
