I have noticed that most of the users on say TT at around my speed have the following tones closed
Gap1 474kHz-479kHz (Tone110)
Gap2 548kHz-552kHz (Tone127)
Gap3 811kHz-815kHz (Tone188)
Gap4 824kHz-828kHz (Tone191)
Gap5 1048kHz-1052kHz (Tone243)
Gap6 1255kHz-1259kHz (Tone291)
Gap7 1501kHz-1505kHz (Tone348)
If i sync over 17mbit, these tones get used, no idea why but we all seem to get it, maybe something set on the msan? Could yours be similar?
