Vlad, you are correct. There is absolutely no requirement to contact Farnborough. I can follow this up for you if you would like but I need to know when it was (Sunday p.m.?). PM me if you prefer.
Blackbushe does suffer from users transmitting outside the DOC of 122.3 (10nm and 3000ft) and it is to be discouraged. Naturally if FISOs warn offending users over the RT they are exacerbating the situation if inviting reply. Maybe that had something to do with it. I don't think WOD is an unreasonable distance at which to make the initial call.
