From Bulbapedia, the community-driven Pokémon encyclopedia.
Professor Oak's Pokémon Talk (Japanese: オーキドはかせの ポケモンこうざ Dr. Okido's Pokémon Lecture), also known as the Pokémon Channel is a radio show. It is hosted by Professor Oak and DJ Mary. The show operates on the radio frequency 4.5, only in afternoons in Generation II but all day in Generation IV; during the morning in Generation II, the Pokédex Show is broadcast.
The show talks about Pokémon and where they are found. In Generation IV starting post-National Pokédex, it also informs the viewers of Pokémon swarms. This also includes the ones from Generation II that appear in a swarm when a Trainer registered into the player's Pokégear would contact them.
At first, Professor Oak was going to turn down the offer of having his own radio show, but Mary's energy and enthusiasm convinced him to host it.
The following Pokémon may be found by listening to Professor Oak's Pokémon Talk.
- In Pokémon FireRed and LeafGreen, one aide mentions Professor Oak's show he's planning, but mentions that it's called Professor Oak's Pokémon Seminar.
- According to one of Professor Oak's aides in Crystal, HeartGold, and SoulSilver, the show is prerecorded. This explains why Oak is always in his lab, even if the player listens to the program while visiting him, and why he isn't in the radio tower while the program is playing.
