I have an R-390 which has a limiter problem. With the limiter off there is horrible audio distortion. As soon as it is turned on the radio sounds normal. I seem to remember some discussion of this problem a while ago re the R-390A. Would appreciate some suggestions. end Regards David Medley 1305 Rockmoor Drive Fort Worth TX 76134 Check my Web Page at: <http://www.davemed.info>
