What do you mean by ‘talk’ ? Are the Two radios communicating (Solid Green Light)? Are you testing the Third radio when the other two are powered or are you testing them in pairs?
Check the settings of the two radios which are working. You’ll see that they are the same. Now, check to see that the one which is not working has the same settings. If it doesn’t, change the appropriate settings to match the other two.
