Cobra 150 GTL DX NO RECEIVE

[JSTAHNKE81]

OK, So i bought a brand new Cobra 150 GTL DX, i turned it on and everything seemed to work fine (ofcourse, it only receives 10 meters out of the box which is dead around here) Anyway, i then preceded to remove R138 which opens up the CB band. I turn it back on and everything is fine (im 100% SURE IT IS NOT ANYTHING TO DO WITH THE R138 MOD, I WAS VERY CAREFUL) Except....there is NO SIGNALS coming in. I here static next to nothing ofcourse wiith no antenna, but when i put in the coax the static jumps up like everything is fine. Basically it is acting as if it receiving on some random unused frequency because i am getting an S3 in noise, JUST NO STATIONS COMING IN!!! Its driving me nuts, cant figure this out. By the way, i tested the TX on my scanner that goes down to 29MHZ. It is DEFINETLY transmitting (atleast above 29mhz) SOMEBODY PLEASE HELP, I AM TOTALLY DUPED ON THIS ONE!!! Any and all help is appreciated, thanks!
