We believe that we experience interference from time to time from a microwave radio beam linking Aviemore police station with the mast which you can see on the hill near the Sluggan Pass to the north east of the flying field.
The interference occurs in the area to the north of the airfield, that is on the most frequently used landing approach! The interference usually manifests itself as a sudden short-lived glitch and is normally more of an inconvenience than a hazard.
Interference is most evident with single conversion receivers such as the Fleet XP-FM. Modern double conversion receivers seem to reject the interference from the powerful microwave signal and are the preferred option.
However, beware of a poor aerial installation on your model, resulting in a weak signal being fed to the receiver.
One of my models has servo leads running to the 2 servos mounted in the tail, the leads being parallel to and only centimetres from the aerial, which is inside a plastic tube inside the fuselage. This setup is susceptible to glitches due to the servo leads masking the aerial from my transmitter signal. A similar problem could occur with the cables of a closed-loop rudder control system.
Loch Insh appears to be completely free from interference problems. As far as I am aware, all the crashery over the years has been due to radio equipment failure or (dare I say?) pilot error.
