Some weren't and were they same type of encrypted speech that I monitored during the pulser sighting. Since then this has proven to be a very interesting frequency to monitor. 288.000 is a downlink with the uplink still unknown. Voice traffic was passed as was data. One of the trickiest parts of military monitoring to get correct.
Intercepts depends on input from military monitors.
Military monitors are just like Mr. Tyler and make mistakes. Twice a year there is a call for casllsigns from my readers and the oblige my request . I also ask them to point out any errors or changes they may have noticed. Every six months we update the callsign lists. Any errors or new callsigns in the last list will be corrected and changed in the next list.
