The New Omnistar satellite covering Australia, the AUSAT, works on 1539.9625 MHz. Version 3.5 of Imap doesn’t use this frequency in its allocation for Australia.
Until a new version of Imap supports the correct frequency, you can use the following manual method:
In the TOOLS/ GPS configure menu, press the COM VIEW button
In the top window enter the command:
assignlband omnistar 15399625 1200
then tap on the SEND button - this assigns L band frequency to the correct satellite
note: leave the command sitting in the top window, so next time you only need to tap the ‘send’ button.
