I'm having trouble entering frequencies with three decimal places in the GTN 750... I have the unit configured for three decimal places but when I input certain frequencies it rounds them up or down and I can't communicate.

Today I tried entering the ground control frequency for KMRY (120.875) and it kept changing it to 120.880

I tried talking on this frequency (120.880) but could not get the controller to respond.

It's probably a simple fix but I can't find it... any ideas??

Thx!

Can you set it back to two?

You should be able to tune 120.87

Hi Ryan,

Thanks for the suggestion... unfortunately I set it to 2 decimal positions and entered 120.87 but it changed it to 120.85 on its own. I even took the frequency from the FREQUENCIES list in the NEAREST menu but it did the same thing.

At this point I'm starting to think I may have to re-install the GTN but I don't want to do that unless it's absolutely necessary.

Thanks anyway, it is much appreciated!
