I set up a custom search 128.0000 - 132.0000 and one result came up a bit strange. In the RRDB 128.9 is ARINC for the Las Vegas Area. The result came in as 128.8916 ??? Makes me wonder if the scanner needs adjustment or is off somehow? I have the step set in auto, modulation AM. I'm trying again with step 8.33 to see results. Just a small head scratch today.
