Cobra 200 noisy RX

I have this Cobra 200, it is a few years old,, but has less than 10 hours on it,, it seems to boom out,, but the receive is pretty weird. There is like 3-5 noise on RX meter, no matter what vehicle, or where I am,, even in garage,, where RX on meter should be almost "0". I have both leads going direct to battery,,, was thinking about putting an additional ground tap on ground lead to a metal surface in cab. this noise, has pretty much always been like this, that is why I never used it much,,,, sure is a sharp looking radio,,,,, can the RF be tuned to clean up the white noise,,, and still get good RX ? Just love the look of this radio,, really want it to work,, hate to just throw it back on the shelf.

 

Yes,, noise stays with radio,, in any vehicle, any antenna, any outside location,, mobile or base setup,,,, driving me nuts,, always been this way,, older radio, with very little use ,, but looks great,,, really sad,,

 

Ok,, thanks,, if this pot is turned back,, will that kill the rx input as well,, but guess it does not matter,, any signal less than 4-5 on meter does not come in well anyway,,,I can turn the RF gain down of course to kill white noise,, but that also blocks the incoming RX signal,,, correct ?

 

Discovered something interesting,,,,, with any radio , I have ever had,,, I seemed to always have the RF gain set to full,, just sort of an automatic thing,,,,never gave it much thought,, just all were set all the way,,,,and adjust the white noise with squelch,,,,, today,, I backed the RF gain down,, thinking well, that eliminates some noise, but also restricts the incoming voice traffic,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,it really sorta' did not,, I was talking to my buddy,, now this radio booms out,,, he said my signal did not lessen the further away I got, so that part is great,,,but with fine tuning the RF gain and squelch,, it seemed to work pretty decent,, well enough, that 4 miles away,, and IN my garage,,, with the door closed,,, I could still hear him,,, and he could hear me,,, now his audio was pretty weak,, but doable,,, again inside the garage,,,,,,,,,, I have never done that before,,,,,,,,,,,really weird,,,,,so,, right or wrong,, maybe the radio is doing the best it can, with all features,,, I was just to dumb to work with it,,,,,, I got this radio,, who knows how long ago,, new,, from Sparky's CB in Illinois,,, got a lot of stuff from this guy,, he always took care of me,, until he started slipping as his age increased,,,, so he may have tuned it to the max,,,,anyway,,,, still doing some playing around,,, again,, always before I gave up, and put it back on the shelf,,,, but always tried it later,cause it is just a cool looking radio. So,, sorry to put you guys into The Twilight Zone,,, maybe I am the one out of tune,,,, Thanks all,,,be safe, be well,, from Bubba in NW Illinois,,,, p.s. I really like the old Turner mics,,,, I just put a new cord on this one,,, got a couple more to re-cord,, and have a really nice one ,still with a nice original cord,,,they were /are great mics,,,,since I may keep this radio installation, I will clean up the wiring and stuff,,
