Meanwhile, two feeders are preparing to bring LSGG back online. I try to coordinate and support both.
Regarding the frequencies: I think the data you mentioned are the new channels in the 8kHz grid. I.e. these data can be entered exactly like that in the airplane and converted internally by the radio. But if you have to enter the effective frequency like RTLSDR, then the frequencies are sometimes different.
For this reason I would say that the effective frequencies are the following (according to AIP):
freqs = ( 136.450, 136.250, 119.525, 130.550, 120.300, 131.325, 118.700, 119.900, 119.700, 121.675, 121.850, 121.750);
labels = ( "Transit", "Arrival", "Departure", "Approach", "Final", "Departure Aux", "Tower", "Tower 2", "Tower/Ground Aux", "Ground", "Apron", "Apron Aux");
The feeders will contact you as soon as the setups are ready.
