Hoenn Sound and Sinnoh Sound are two radio stations that you can only access in the post-game of HeartGold & SoulSilver. They let you encounter Gen 3 & Gen 4 Pokémon in specific areas while you’re listening to those radio stations.
The reason for why these radio station were added into the remakes is that in Pokémon HeartGold and SoulSilver, the regional Pokédex was not significantly changed compared to the original GSC games.
This means you cannot find any of the newer Pokémon in the wild by default.
To partially solve this, the HG/SS remakes introduced a few new mechanics that allow you to encounter some of the Pokémon from Hoenn and Sinnoh in different ways such as via swarms, via headbutting trees, or by playing two radio stations (Hoenn Sound & Sinnoh Sound).
In this guide we will explain how to encounter rare Pokémon with the Hoenn and Sinnoh Sounds on your Pokégear, and we’ve added a list of all the different Pokémon you can encounter with these radio stations.
What Are Hoenn Sound & Sinnoh Sound?
The Hoenn and Sinnoh Sounds are special programs that play on the Pokémon Music Channel during specific days. You can access these programs after unlocking them by using the Radio function on your Pokégear.
The Pokémon Music Channel plays these sounds based on the day of the week:
- Hoenn Sound plays all day on Wednesdays
- Sinnoh Sound plays all day on Thursdays
Hoenn Sound plays a version of the Route 101 Theme from Ruby, Sapphire, and Emerald.
While the Sinnoh Sound plays a version of the Route 201 Theme from Diamond, Pearl, and Platinum.
Like with the other Radio channels in HG/SS, the music will continue to play even after you close the Pokégear. So the music will only reset once a new musical track is triggered to play.
How To Unlock Hoenn & Sinnoh Sounds
You will get the Hoenn Sound and Sinnoh Sound radio stations as soon as you unlock the National Mode on your Pokédex.
You can unlock your Pokédex’s National Mode by boarding the S. S. Aqua for the first time in Olivine City. But you will need the S.S. Ticket for that, which you can get from Professor Elm after you defeat the Elite Four for the first time.
This means Hoenn Sound & Sinnoh Sound are both only available as post-game radio stations.
After obtaining the S.S. Ticket from Professor Elm in the post-game, just head over to Olivine City and enter the port located in the southern part of the city, directly below the Pokémon Center.
Upon entering, Professor Oak will greet you and upgrade your Pokédex to its National Dex Mode.
Once your Pokédex has been upgraded, The Pokémon Music Channel should be able to start playing the Hoenn Sound and Sinnoh Sound every week.
How To Use Hoenn Sound & Sinnoh Sound
Playing the Hoenn Sound and Sinnoh Sound will alter the encounter tables in certain areas of the game to include new wild Pokémon that were originally from whatever regional game matches the music you’re playing.
So Hoenn Sound can spawn wild Pokémon from R/S/E, and Sinnoh Sound can spawn wild Pokémon from D/P/Pt.
You will have approximately a 40% chance of encountering a wild Pokémon from Hoenn or Sinnoh on certain routes, depending on which music is playing. We’ve added a full encounter table below that lists all of the possible encounters & where to find them.
In most areas, there are two Pokémon from each specific region that you can be encountered when the Hoenn or Sinnoh Sound music is playing.
The exception is for wild Shinx, which can only be encountered exclusively in certain areas while the Sinnoh Sound is playing.
Since your radio music resets after every wild encounter, you will need to reopen your Pokégear and tune in to the Pokémon Music Channel after every battle.
This can get tedious, but as a post-game feature it’s not so bad.

Below we have listed all of the wild Pokémon you can encounter while each music station is playing, as well as the locations where you can find them.

Keep in mind that not all the new Pokémon can be encountered this way. Some Pokémon are only encountered in the Safari Zone, some are only encountered by headbutting trees, and some are only available during swarms.
There are also others that cannot be obtained in the HG/SS games at all.
Or some Pokémon like Snover and Tropius are only available if you have a PokéWalker, while others like Leafeon, Glaceon, and most Legendary Pokémon can only be obtained exclusively from trading.
