[1000mp] 1000MP Clarifier Problem

Sat, 22 Feb 2003 23:37:43 +0100

Hi All,
One of my friend resoldered the wires from RIT to XIT. Of course, his XIT
worked right with no problems. After that he has properly working RIT in XIT
knob and no XIT at all. It is strange, that in so good radio you have to
make that kind of "tricks".
