For listening, start with a 500 Hz receive filter and an audible CW tone around 600–700 Hz, if those controls are available. Narrow the filter to about 250 Hz when nearby signals interfere.

Click Apply and save after entering each profile. As with the previous table, 60m requires separate settings because of its special operating rules.
