On occasion I have tried using the narrow selectivity setting, but this makes the audio very muffled, often to the point of un-intelligibility. Turning the treble all the way up and the bass all the way down often helps, but the audio still isn't as good as with the wider selectivity setting. (Turning the treble up seems to emphasize the interfering station as well.) Usually I just go ahead and use the wide selectivity. Is this (1) a problem with my particular set; (2) a problem with the 803A; or (3) a natural consequence of narrow selectivity? Would a more expensive set having even narrower selectivity have even worse audio quality? Any suggestions for improvement? P.S.: Antenna is a dipole, but use of the internal whip gives the same general behavior. ________________________________________________________________________ Ray Arritt | Dept. of Physics and Astronomy | Univ. of Kansas | Lawrence, KS 66045 | arritt@kuhub.cc.ukans.edu | arritt@ukanvax.bitnet |
