GTN 750 ATIS frequency

[tamsini 278]

Hi all, I have a weird problem. Wherever I am stationed in North America (have not tried abroad), when I want to check ASN ATIS at 122.00, the channel on the GTN 750 constantly points to Boston FL FSS, It was working fine up until I updated the F1 GTN to v1.19. Anyone seen this before and, if so, HELP!

The frequencies on the GTN are based on the navdata that comes with the unit.  I don't recall exactly but I think airac 1607 is the data from the latest patch.  So what that means is that in real life the ATIS freq might have changed.

In the US, above 5,000 ft AGL, FSS is at 122.2. Below that altitude, you find local FSS frequencies on the sectional charts. They are the two numbers just above the box inside each VOR compass rose (if available). They are also 122.x, so it's possible that 122.0 is being used by a local FSS. Did you ask about it on the HiFi official forum?
