Quote:I just peaked it for the best signal at 600.

NULL it for IF frequency, originally it would have been null for 500khz., to reduce signals from the distress frequency. There should be a defined dip for 500, may also dip at IF. Any "stray" IF would be blocked by the trap.

Glad to hear the problem is now gone!
