I just installed the European Jeppesen Navdata on my GRT EFIS Sport EX, and when I look at airports around me, they all have issues with the frequency.
I know it's hard to see in the photo, but these frequencies have errors on the right side of the decimal. They are 8.33khz frequencies so perhaps the GRT software is struggling with them? Anyone else seeing this? BTW, this is the first time I've loaded the Jeppesen navdata on my GRT so not sure if this is a new problem or not. I have other sources of navdata on my ipad and iphone, so I'm not grounded.
