If it exists, a ham will either try to bounce radio waves off it or use it as an antenna. While Yih has an ionosphere that can be exploited for radio propagation at frequencies between 3 and 30 MHz, it also has a ring, which can reflect signals in the VHF and UHF ranges. As a much larger, closer, and most importantly, stationary object, Yih's ring is a much better reflector than Earth's moon, meaning ring bounce is a practical propagation mode, not just a “because we can” mode like Terran earth-moon-earth. It has some drawbacks, like only being viable at mid-latitudes.
Focus has a multi-year solar cycle much like Sol. The Farspeakers have a feast that marks the beginning of a new cycle.
