Re: AM Broadcast Stations Distorted

1070 kHz is on the AM band Los Angeles. ? Is it a typo or you are definitely saying 1070 is not on AM? ? Try listening to WWV on 5, 10, 15 or 20 MHZ on SSB and AM. Is the AM signal clean? If so, then possibly something the LF portion up to 1.8 MHZ in the radio may be bad. ? ? --------------- Regards, ? Tony ?
