And to be honest its not really the problem of the pilot if the unit is too tight to provide a secondary radar feed
Mad Jock and others raise a good point regarding secondary radar and safety. I fly to Southend a lot and my own opinion is that most of them are very obliging and do a good job with the tools that they have.
They don't have any information about aircraft heights though which is not conducive to situational awareness or flight safety. As they are working traffic on instrument approaches outside of controlled airspace this is an accident waiting to happen.
Many times traffic is called for example "crossing left to right 1 mile no height information" - "further traffic 12 o'clock no height - slow moving"
They would like to setup some software on their PC for a total cost of £50 - £100 which would show mode c aircraft in the area but as this is "NOT OFFICIALLY APPROVED" they must keep their (and our) blindfolds on. Farnboro do have secondary radar so if you can talk to them the service is safer.
Good job Southend ATC - Hope you get some software soon !
