There are subtronics in "Sargasso of Lost Starships" but a transonic communicator in "The Star Plunderer" and the rest of the Technic History has modulated hyperpulses whereas there is a hyperbeam in For Love And Glory.
There is an "ansible" in Ursa Le Guin's Hainish future history.
Compare James Blish's Dirac transmitter and other interstellar communicators. Also, Communication. For more on his CirCon (circum-continuum) radio, see ASK Haertel.

Kaor, Paul!
I think what we see here, in Anderson's stories, is him moving away from any kind of FTL radio as his thought on such things matured. Thus we see the "subspace radio" of Anderson/Dickson's Hoka stories and the "transonic communicator" of "The Star Plunderer" being replaced by the more plausible "modulated hyperpulses" of the rest of Anderson's Technic stories.
