I hadn't thought of that, but yes... remember that many stations on D-STAR are running un-attended AUTOMATED data transmissions in the so-called "low-speed data" feature of the voice transmissions. GPS beacons are one great example. They're not keying over you, their beacons will wait until the channel is clear if they're set up correctly. Also note that SOME gateway/server operators have set up some beacons from the Gateway/Repeater system itself. Look at the data line on your rig to see if there's information going past other than the callsign. W0CDS transmits a timestamp at the top of every hour on all three band modules in order to know they're all still operating correctly, and as a mild "public service", here locally. If users want it disabled, we'd probably do it... never any complaints that it was there. It helps folks figure out where the coverage pattern really covers too, as they travel around the area. -- Nate Duehr, WY0X n...@natetech.com
