Hi Glen,
first of all, welcome here at Navigraph and thank you very much for your report.
I have checked all our source now, including the AIP Guatemala. All information what I have found say, 114.90 for the La Aurora VORDME. You wrote the “correct, published AUR frequency” - please can you forward us your source of this, that we can report this to Jeppesen.
Here what I have found:
From our charts, which reflects also the navdata because the source is identical for this kind of information:
… the Jeppesen chart:
… and last but not least from the AIP Guatemala:
You see in all three cases, the frequency 114.90 … and therefore you see this (and must be used this) in MSFS, with our data installed:
So, please be so kind and forward us such official source, that we can check the possible frequency change for this VORDME.
Thank you very much,
Richard
