20 watts is very good considering it comes from the factory with only 4 watts. 4 watts is the leagal wattage allowed by the FCC. But FCC doesn't care any more.
If you need more wattage then that, you will need to get an AM linear amplifire. The radio's dead key must be set to a lower dead key to run it with out burning it up.
