In the process of new controller being updated and tested but we use the following.
DTMF burst puts repeater in skywarn mode: Repeater id delay wont id over people talking, skywarn spotter tone tone a 1080hz tone b 701.0hz long tone 1050hz weather tone. Dual tone activates the team long tone is used when a warning or watch is issued. This is all programmed of the one dtmf command then a seperate command for the dual tone or single tone. Also personel can send the tones from their radios most of our users utilize commercial equipment for ham radio operations. --- In [email protected], "Jeff Kincaid" <je...@...> wrote: > > A 30 second DTMF blast?
