rumour has it that some people have been speaking to Stapleford whilst landing at North Weald
other day someone was speaking to Stapleford and landing at Fowlmere (thinking they were talking to Duxford).
Conversely I have approached Stapleford while talking to Cranfield (who couldn't hear me).
Easy to do. Only one decimal different. Fortunately I realised my mistake before joining the circuit.
