I hope this is the right sub-forum...

I'm trying to put together an article on the AMES Type 85 radar. This was originally part of the Plan Ahead network. According to Gough, pages around 179-181, this would have five stations with Type 85 and Type 85, and two Type 80's from the older ROTOR.

However, the map of the system on page 145 shows only three stations with Type 85, along with the two Type 80s, one of which also has a Type 84 (Buchan). There's also the three passive receivers.

So... anyone know what the deal is here? Any other sources on Plan Ahead I should be reading?
