CB radios and SWR

My cb radio just sorta works. If I can't throw a rock and hit you, you can't hear me and visa versa.
Nothing wrong with it except it need adjustment, SWR adjustment. I think.

Does anyone have an SWR meter that I can Borrow?

If not...

Ebay has some for less than $10.
If I get one...would you all want to borrow it?
I hate to buy one just for 1 radio.

I bought one for just my radio

FPKites and I both have one.

I normally volunteer mine out but I seem to have issues remembering to bring it to trail runs.

I would discontinue using your CB until you can verify your SWR isn't too high. Too high and it'll fry your CB.

Might be too late then... It has been in the jeep for better than a year, untuned.
The cb was a Wally World $30 special, so it is certainlly a top of the line model....not.

What are the symtoms of a fried radio?

Would be worth putting a SWR meter on there and see what the reading it - perhaps it is just too low.

This includes writing it on your hand and still forgetting...

I think it's directly related to retina burn from sunlight glinting off of polished calipers Jay....see? I can blame anything on Jay!

Tom, the $10 SWR on ebay works just fine. And if you don't wanna get one, just as Arlo said. I've got mine, he's got his. In fact, mine's a semi-permanent fixture in my rig at the moment...when my spring broke, it was enough extra length to correct my bad SWR reading

I'd be willing to bet that your range issue is directly tied to SWR

The cb anntena is about 4 inches from the mounted Hilift jack.
You can see it here.
Will the anntena need to be moved to make the cb work well?

Hard to say, the SWR reading will most likely change drastically when the hi-lift is there and when it isn't. It would most likely affect your broadcasting to the left(drivers) side.

Not postitive, but it might be okay. I would pop up a post in the electrical section though to see what others think.

Thats the EXACT location I have my antenna mounted and it worked out really well for me when we went to Kelly Flats. I seemed to have great range (and I never tuned it because Arlo forgot his SWR meter!) So I wouldn't worry about the location.

This picture makes my antenna look A LOT longer than it really is, I beleive its the same size as yours.
