Here is a tester of the pre-switchover data for the transmitters that I have data for.
It is the "horizontal" data, I have not included the 3D data in this draft.
There may errors and problems with this, I have not checked the data by hand yet - it's a draft!
Just a note - the outside of the circle represents ERP-0dB, then ERP-1dB and so on. The data is actually more precise than shown, but this does allow you to quickly see the data using the drop down box.
