You get it in Kanto, in Lavender Town. Go to the radio tower and talk to the dude with the brown hat.
You go on the Pokegear and go all the way to the top of the radio and that's the EXPN card (EXPN card is the poke flute)
You have to get the expn card to upgrade it
what expn card<-----Why in the world did this person answer this and not know the answer? Anyway you just get it to be able to use the radio on the pokegear in Kanto.
Go and talk to the gentleman at lavender town's radio tower.
The EXPN card is on the first floor of the radio tower in Goldenrod city.
He is next to a sign against the north wall. He should give you the EXPN card. The card will allow you to have access to the Pokeflute channel.

you go to lavender town and go into the radio tower to gt the expn card to make it so your radio works in kanto
In Pokemon silver after you get the expn card you will get a Pokemon flute melody on the last line of your radio which you can use to awaken the sleeping snorlax blocking the way to the cave that leads to Pewter city
