Common signal found throughout Michigan. Can have various rhythms. Did find out on KB9KUD that this type used for updating transmitter data...

Edit: this signal disappeared as of the end of October. Another one is still in use around the area, but with twice the rhythm speed, and on a different frequency. 461.8125

  1. 2: this signal has its license renewed as of today, Jan 28. Signal is actually twice as strong and affects the entire noise floor on the part of that spectra.
