I have been able to build the radar, but I cannot do the initial research. All of the dependent research has been completed. After placing the Infinite Radar it is stuck at 'Disabled by Script'.

Can you clarify how you are not able to do the research? Can you post a screenshot of the tech tree? You should have a research for infiniradar range which becomes available right after researching the infiniradar itself.

Once the radar has scanned all the chunks in the available range, it deactivates until more range has been researched.

I haven't done any of the infinite radar research, the infinite radar was unlocked by default, I am currently playing with Pyanadons. The pre-requisite research appears done in the Tech Tree, but I cannot start the initial research.

Can you post a screenshot of your tech tree? Unless Py adds additional stuff to the technology you should be able to research at least "infiniradar" (which unlocks the radar recipe) and "infiniradar range 1" (which increases the range by +4 chunks). Please bear in mind that successive research requires more science packs, and Py is known for their excessive recipe chains which makes progressing the infiniradar quite cumbersome.

Also in v.2.3.0 a GUI is added when hovering an infiniradar. Can you post a screenshot of that GUI?

Also in v2.4.0 I added mod startup settings to change the prerequisites to automation science only. This should also solve your problem.

Please let me know if you need any further help.
