I've had the best luck with this radio. I had to buy a radioshack SWR meter and a 102" whip antenna to get the radio working perfectly(1.5 SWR). I have the HG A1500 antenna and it isn't really the best for this radio (even though Cobra recommends it). Now all I have to do is find a non destructive way to mount the 102" antenna to my car. LOL

I have to wonder though, with CB technology being as old as it is, why has nobody made an easy to understand (non laborious reading) tutorial about this technology. There are lots of resources on the web, I know, but I feel like it's overloading sometimes and it loses me in its directive. I'm a hands on AV learner and I wish somebody would make a simple step-by-step presentation that serves as a back bone for the more complex issues without putting me to sleep. LOL

Well, this is my first post, I hope to hear from you soon.

I know what you mean about falling asleep.
Lou Franklin does his best to explain in simple terms most of what you need to know for the beginner in his book, THE SCREWDRIVER'S EXPERT'S GUIDE.
If you need a book to get started with that won't put you to sleep, there was a book from Radio Shack by Forrest Mims, III.
called, Getting started in Electronics and it's funny as well as very informative and easy to understand.
How far is it.
Twice it's length from halfway.
