I noticed you require Electromagnetic science packs to research the MK2 Radar, in addition to the Metallurgic science packs.
Why not include some ingredients from Fulgora to craft the MK2 Radar? Currently the recipe is just 1x radar and 5x Tungsten plates, which feels kind of boring. You might add some more ingredients, and maybe multiple MK1 radars? While you're at it, throw in some holmium and/or superconductors?
Just an idea to make these very slightly more interesting to craft.
I know the MK2 Substations from your other mod even require tier 3 Efficiency Modules, which is kind of pricey. Maybe you could modify that recipe while you're at it, to include more than just the modules and Superconductors (since it also requires Metallurgic science to research them too). Of course those require Cryogenic science even... not sure why.
