Automatic FSK polarity selection on TX side

Browse Source 
This is done by simulating two cells with different polarities.
On first message from mobile station, the cell with the correct
polarity is used, the other is disabled.

On RX side the polarity is not selected, since FSK decoder detects
polarity for every frame.
