For the last several days I keep hearing what sounds like a 1000 Hz tone on one of the Safe-T channels on the Petersburg Tower. It's about 1 second long every few minutes. Any ideas why?

Also this channel never ID's with cw like the other channels.
No voice before, or after the tone?

No voice. It has stopped since this morning. I heard it all weekend, every couple of minutes. In fact, I never heard any voice activity on this particular frequency
Hello Indiana!
On my local system, 1000Hz tones have been used for a couple of things..
1. Test tones enabled by a tech.
2. Marking a repeater (pre and post PTT) that is having hardware issues.
I've heard repeaters on this system (753f) give tone before and after a voice call when they are near the end of their useful life. I don't know if it's an automatic function or if it's coincidental (kind of like letting the smoke out), but it's a fairly dependable indicator.
