Hi Brian,

Thanks for the reply but I am alittle confused by your answer

Do you mean 10 seconds for each frequency or 30 - 50 seconds EG;

1604Hz - 10 sec or 30 sec or 50 sec
2008Hz - 10 sec or 30 sec or 50 dec
2128Hz - 10 sec or 30 sec or 50 sec

or are you talking about sweeping each side of primary frequencies

I am still a little new to this idea of Scanning, you may need to explain in more detail please Brian

Kind regards
