or velocity is proportional to radius. I.e a bigger radius means greater linear speed?

For the motion of a satellite in Earth orbit in uniform circular motion, we have centripetal force due to gravity alone. Equating the force of gravity to centripetal force we obtain

V=square root of :(GM/R)

i.e. speed is now INVERSELY proportional to orbital radius.

I don't understand what's going on here. How can a centrally directed force, being the only thing causing acceleration, lead to two different relationships between V and R?
