If I start any of those planes in EDDH and select Equipment - Radio Settings - ATC services in range - EDDH - ATIS on COM1, I hear nothing. /Instrumentation/comm/ shows no atis string, station-id is "Hamburg twr".
If I do the same in the UFO, station name is "Hamburg ATIS", there is an atis string present and it is read out via voice synth...
Thats a problem with the airport information file (apt.dat).
The frequencies are stored with 2 decimal digits. In this case '123.12'.
This was enough in the past because radio frequencies had a spacing of 25kHz.
Possiple frequencies are 123.100, 123.125, 123.150, 123.175 and so on.
Most radios showed also only 2 decimal digits. ATIS of EDDH transmit on '123.125', but the radios display only '123.12'.
Today, the radio frequencies have a spacing of 8.333kHz.
If you set the frequency via dialog, the radio will be tuned to '123.12'.
The code recognise that this is now invalid and round down to the next valid channel and that is '123.115' (in real 123.116667 MHz).
The Cessna 172p support the new spacing.
