I am not sure where to post this so I thought I'd ask here and get a referral to a more appropriate list ... Why is it that late in the afternoon a BC radio station on 1450KHz wobbles and 970KHz does

So to eliminate the "flutter" (that's the term I was struggling for, thanks) - I need to try some sort of directional antenna and/or perhaps a nulling system (active or passive)? -- Thanks! & 73, doc

Turns out that the problem was mostly at the dash switch. I had to pull the dash to re-run the AM/FM radio antenna cable and in so doing discovered that the cable connector to the switch was barely h
