I’ve noticed that 101.3 is actually a few seconds behind 1490.
back when we used high earth orbiting Viasatr for our stream and STL.. wed shoot from mcgrath up to the satellite, down to stream guys..out to the stations that carry us.. and sometimes id listen to that return audio on our via sat.... the delay was incredible.Digital encoding and decoding will cause a delay. On Tunein the delay can be one minute behind.
