James Blish is the master of diverse means of interstellar communication. See:
The Dirac Transmitter
references to the CirCon radio here
Poul Anderson also discusses this subject. In his Technic History, instantaneous hyperwave pulses can be modulated but only for about one light year whereas long range hyper-communication does occur in For Love And Glory.
Anderson's World Without Stars presents one more means: electron patterns can be instantaneously space-jumped. (VI, p. 39)
OK. Be here tomorrow or whenever.

Kaor, Paul!
We do see Duke Edwin of Hermes speculating about the possibility of using hyperwave beacons for transmitting information and messages at FTL in A STONE IN HEAVEN. Earlier studies had concluded that the cost of building the massive numbers of beacons needed for such a system was too prohibitive. But Edwin wondered if a means of producing such large numbers of relatively cheap FTL hyperwave beacons could still be worked out.
