Re ham radio uses HF waves ,amateur radio enthusiasts use any frequency from 1.8MHz through 25GHz, earth or space we communicate
 The speed of light,if it changes by any significant amount no antenna on or off the earth would resonate at its fundamental frequency,try building an antenna.

The issue is where the speed of light changes.
If it is constant on Earth, but then changes a few dozen km's above Earth, due to a different medium, then that will have no effect on your antennae on Earth.
It would only be a problem for space based antenna, which sandy would claim don't exist.
