Sorry guys, with family commitments I have not been able to monitor the threads that have developed somewhat beyond my original post and the issues around TMZs which clearly have some interest!
Really appreciate all the input but I think this needs now to terminate as it has some of it has got a Chineses whispers feeling.
My fault that I did not pick up the Farnborough Notam outage and call Essex Radar albeit by the time I had contacted them it would have possibly been a retrospective. I understood my Mode S was with ALT on. I will try to get up today and check with Southend that Mode C is operating. Otherwise will get the radio guys onto it. If I neglected to select ALT before departing North Weald then again my fault. It will be on the immediately before departure check list! Generally it is off on the ground simply because of the spurious or multiple returns received on Stansteds radar.
I hopefully will not need a solicitor unless NATS/CAA decide to take it further. That's why I have AOPA membership. (A plug for us all to subscribe and have some organisation supporting us)
Thanks again for all the input. Last thing I wish to do is compromise North Weald operation which is always under pressure from the owners who wish to develop it and remove flying. Neither Stansted Ops who are busy enough looking after the commercial boys. (Do miss shooting ILSs there when I first took my IMC)
I just wish NATS would stand by their commitment to fund and provide the Farnborough North on a 7 days a week 8am to 8pm basis as they originally stated. Outages are often necessary but all day for a unit that looks after this particularly busy piece of airspace.
My last word.
