I think an incorrect atc frequency is listed for 74P. Ifly lists 132.62 for LA Center. I was able to contact center on that frequency, however was told that is a high altitude frequency. I was redirected to 124.62.
I think I found the problem. Ifly correctly lists Mt. Potosi as the nearest station, but listed the hi altitude frequency instead of the low alt. frequency in the listing for 74P.
Is this a common issue?
Does iFly always pick up hi instead of low center frequencies? If so, I think this is a mistake, since I'll bet most users are flying at VFR altitudes.
