This may not be the proper forum to ask this question, but inquiring minds want to know….
We know that the first 60m channel frequency was changed due to the frequent digital transmissions on that frequency, presumably government in origin. Other than that, how often do federal users use the 60 m frequencies we have been granted on a secondary basis?

I cannot recall which channel but when the digital transmissions occur operators just have to wait. |
5371.5 seems to be most active ... usually I just go QRT. Sometimes switch to another clear frequency. |
3 or 4. Bursts of data quite regularly and strong. CODAR formerly made many channels useless until the Rutgers agreement was reached |
CH 3 always has a beaconing data transmission |
No, but on occassion I have needed to stop a QSO because of "odd" digital signals on the band. It may have been the government. |
Wait until the other signal stops. |
I have had QSOs ended by data transmissions on 5366.5 and 5346.5. I Went QRT. |
5366.5 always has digital noise and is usless |
Though channel 3 has been unusable for a long time. |

Channel 1 and Channel 3...QSY to another free channel. |
