Cobra 75 - tunning
I just bought a swr meter off ebay and while i am waiting for it, a couple questions came to mind.....
Do I set the squelch before i start to tune the Antenna? If anyone can give me some direction on how to start this process, that would be great. the squelch is what i am having trouble with? thanks in advance!s

i am just saying, do i need to set my squelch before i tune my antenna, if that even makes since? i am a first timer at this so i have no idea what i am talking about. apparently the squelch is for getting only good channels in? or am i completely wrong with what sql does?

Your sorta right. The Squelch is for cutting down the noise you may be receiving. It's like a water gate (I read this) if it's all the way open you'll receive everything, if squelched all the way you won't receive anything. When your hooked up and receiving you may get a lot of noise, turn your squelch until you just barely cut the noise.

ok, i guess i do not know what i am doing. I understand how to take measurements from the swr meter. So when do i actually get to turn the little knob on the tip of the antenna???? any help would be great, thanks!
UPDATE: nevermind, search is my friend!!!!!

After it was tuned I went out on the highway and see what i could hear. Heard some good stuff! However, i went on a little side road to look at the swr meter again and all channels are reading above 3 for swr.... i unplugged from meter and plugged everything back in to meter, and then started from scratch. Went to channel one and adjusted the setting...then flipped the switch to swr and it acted like it wanted to go and then it just shot right back to red. All channels are reading red now....
Do I have a bad connection somewhere, or is my swr meter bad? how do i find out???

Your top problems for this are going to be a short or improper ground.
It definitely could be your meter though. Just so you know, I bought a meter from a reputible company online and tried using it for months to no avail - finally I called them about it and they agreed it was broke, but it was too late for me to return it. Made me mad, but it was my own fault for taking so long to call. This was a brand new SWR meter - so yes, they can be bad.
