I quote:

"The Venus Equilateral" by George O. Smith may or may not mention ham
radio, but it's about a space station in the right place to relay
communication, somehow the author felt a need for people on the station.

So did Arthur Clarke. His novel which is credited with first mention of geostationary communication satellites assumed manned satellites. I believe there was some mention of a need to change tubes/valves.
