Newer satellite mode-names do use a combination of two letters, representing the up- and down-link band.
As there are: H 15m, T 10m, V 2m, U 70cm, L 23cm, S 13cm, C 6cm, X 3cm, K 1,2cm, Q 6mm
Maybe it might be a good idea to give the user an editable list, if this is not to much to change. This might be a good way to be prepared for any future changes. Of course you might fill a default list as a starter.
+ I have sent you a new version of DXKeeper that if on startup finds a file named SatelliteModes.txt in its Databases folder, loads its Satellite Mode selectors from the satellite modes specified in this file, one line per mode. Otherwise, the Satellite Mode selectors are loaded with the default Satellite Modes made provided in previous versions of DXKeeper.
+ Please let me know now it goes...
