It does sound like Bletchley Park have got some jobsworth for managers now, and its been going on for over a year.

The Milton Keynes Amateur Radio Society (MKARS), the resident radio club at Bletchley Park for nearly twenty years, will be leaving the Park as of the 1st January 2013. To mark this occasion MKARS will be holding a 'QSO party' on the weekend of the 15th-16th December.
All MKARS members and ex-members are invited to come and operate GB2BP from Generator House 2, our current premises at Bletchley Park, for the last time.
GB2BP and MKARS will in the future only be operational from Bletchley Park by invitation during 'radio related' events.
This is possibly your last chance to operate this charismatic call sign. Be a part of MKARS continuing proud history. If you do not normally attend MKARS events, this one is a 'MUST'. So put the Christmas shopping on the back burner and be there.
In the future you will be able to say 'I WAS THERE, my name is in the log'. Will has threatened to cook burgers and Dave is trying to obtain a 'Big Linear'.
Tea and coffee will be provided. Hopefully some beer as well.
The event will start early on Saturday morning, as soon as we can get on to The Park and finish when we have to leave, and the same again on Sunday.
We, MKARS, can walk out of Bletchley Park with our heads held high knowing that all those years ago, when Bletchley Park was on its knees, MKARS was one of the many local groups that helped make the Park into the great museum it is today. MKARS is a great club with a great future. Be a part of it!
We have not lost The Park, The Park have lost us.
