Skydemon has incorrect frequencies for many airports in Slovakia (LZBB FIR). For example, LZTN in SkyDemon says 123.605, while correct (in accordance with up to date AIP) is 123.600. There was a plan to update all frequencies in LZBB FIR to 8.33kHz in April 2018, but they kind of messed it, so individual airports are being updated through 2018, and there are still quite many airfields where old 25kHz frequency is still official. Due to this, I cannot rely at all on SD when it comes to frequencies.
