I own a Cobra 29. Its a 23 Channel rotary channel selector. I love this little radio, it does a great job for me, but my only down fall of it is that it has very low receive. With the RF gain turned all the way up it still does not have the receive capability of my newer radio which picks up to much . Is there a way I can boost the receive on my Cobra 29? I've done the usual of Googling for days trying to find information but all i find is how to boost the receive of the Cobra 29 LTD Classic and such. Any suggestions would be greatly appreciated.
