Link is Up, Receive Signal is too Low

Go through below checklist to troubleshoot your installation.

After changing the feeders for both sites from 38 GHz to 26 Ghz, the radio configuration is still showing 38GHz and the RSL became -57 dB instead of -35 dB. Is there any justification for that?

The radio equipment should be swapped along with the feeder swap. Both radios and feeders should be operating on 26 GHz.

When the radio was muted, the RSL is -80 dBm. Is there a justification for that?

This means that other links are interfering. The used channel needs to be changed.
