To use the radio's hidden frequency:

1.) Equip the cigarettes from your inventory.
2.) Access the Radio Screen.
3.) Select 140.07 as the frequency with your controls.
4.) You can listen to all of the sounds of the game.

To get the hidden tape:

1.) Equip the Zanzibar Land Broch given to you by Nastasha.
2.) Stay in the sauna until it changes to a door key.
3.) Head to the sleeping quarters in the Zanzibar Land
fortress.
4.) Keep looking until you can open a locker with the key.
5.) The tape is inside. You can get it and use it as a
distraction on the Zanzibar Land soldiers to stay put.
You can sneak up on them and kill them. But, if you
move to another part of the screen, it'll be removed.
