WSEA699 Posted Sunday at 03:17 PM Report Share Posted Sunday at 03:17 PM Hi all! I was on a local repeater recently and every so often there were tones coming through like the ones on fire calls. Thoughts? Thank you in advance! Quote Link to comment Share on other sites More sharing options...
0 BoxCar Posted Sunday at 03:20 PM Report Share Posted Sunday at 03:20 PM Probably the station ID being broadcast in Morse Code. Quote Link to comment Share on other sites More sharing options...

Could be as @BoxCar suggested, but maybe a user is sending dtmf tones. Quote Link to comment Share on other sites More sharing options...
0 WSEA699 Posted Sunday at 03:38 PM Author Report Share Posted Sunday at 03:38 PM Definitely not morse code so it's probably dtmf tones. Thank you! Quote Link to comment Share on other sites More sharing options...
0 Socalgmrs Posted Sunday at 03:55 PM Report Share Posted Sunday at 03:55 PM Are you sure it’s a gmrs repeater and not a public safety repeater? Quote Link to comment Share on other sites More sharing options...
0 WSEA699 Posted Sunday at 04:03 PM Author Report Share Posted Sunday at 04:03 PM 100% sure, it's the Ashland, MO repeater. I live in Columbia, MO which is 13 miles north and using the repeater I can reach my family here in town which I can't do with simplex. I love technology!

0 WSEA699 Posted Sunday at 04:12 PM Author Report Share Posted Sunday at 04:12 PM That's exactly what it sounded like. What would be the reason for transmitting dtmf tones on a gmrs repeater? Thanks again! Quote Link to comment Share on other sites More sharing options...

Or someone simply doesn’t know how to use their handheld radio. WRYZ926 and WRXB215 2 Quote Link to comment Share on other sites More sharing options...

0 WRYZ926 Posted Sunday at 09:44 PM Report Share Posted Sunday at 09:44 PM You can also use DTMF tones to call specific radios too. And the Ashland GMRS repeater is an excellent one and at a good location. I can get into it from Montgomery County which is about 50 miles east of Columbia. I do struggle a little getting into the Ashland repeater with 20 watts but normally do fine at 50 watts. Quote Link to comment Share on other sites More sharing options...
