Turn the FM radio OFF and then ON again. The radio may pick up static or fade when you are on the move as the radio signals become weaker when you move further away from transmitting stations or are blocked by hilly terrain or tall buildings. You may also notice improvements for other stations as you ride closer towards them or when in open spaces. You may hear multiple stations at times if the signals are relatively weak from stations with frequencies close to each other. The FM radio of your Raptor-i should not be compared with those in your car or home as these have dedicated antennas that are larger in size and uses more sophisticated circuitry.
