The user who run the Logger and want login the digital communication MFSK type can't do that because the login software don't recognise this mode. If you wish to recognise the Logger the MFSK digital mode first of all download the archive of bandplan. Copy and paste the bandplan.db archive to the Logger's directory (choose overwrite). Now run the Logger and follow the picture to configure step by step the installation of MFSK mode to your Logger's data base. Good luck!!!
