    Wondering if anyone has had this problem with the Icom 740. I like my old gear and love the receiver on this radio, but it developed a problem after I replaced the complete front of the rig because I had a processor switch problem and turned it on. The frequency display started scanning at a rapid rate on 24.5, 28, 3.6, and 1.8 Mhz, on 28, 21, 18, 14, and 7 Mhz all is Ok.
    I have full output on all bands. The bands where it scans I can lock the freq and it has full output and reception.
    This is a good one, does anyone have any ideas where I should start? I checked all connections and cleaned all pots and switches but no luck. Is it time to replace this back up rig? Any help would be appreciated.

    Some people like scanners.

    If you can't fix it, feature it.:)
