I can not research Radar

When I start a game of freeplay I can not research radar. I search for "radar" in the research text box under "List of Technologies". All I get as a result from the search is "Fluid handling". I have no idea why.
I bought my Factorio from the dev site factorio.com which redirected me to Humble Bundle. I installed using a tar ball. factorio_alpha_x64_1.1.107.tar.xz

That is all the info I can think of

Radar's don't need a research, they're unlocked from the start of the game.

I feel dumb. Thank you.
