How do you find out how? Quite rarely they publish their COM frequency.
Always listen, ok, but mandatory increase of gaggle in the air, no.
The CAA do not like 'extraneous' talk on display frequencies as it has been identified as a contributory cause in several accidents, either by distracting the pilot displaying or by blocking the frequency thereby preventing air to air comms when more than one aircraft is displaying hence the frequency is rarely published.
