Sound horror stories aren’t confined to musicians. The British Gliding Association used to have an aircraft with an audio attachment to the variometer (the instrument which tells you when you’re going up and when you’re going down). On occasion, this was reported as being able to receive Radio 4.

Unfortunately, cheap, consumer quality, music equipment is often incapable of rejecting radio frequency interference - how many of us remember hearing taxi conversations over the PA in days gone by?
