Part	Setting	What you hear
Radio band	Bass cut below 500 Hz, treble cut above 3.6 kHz	The thin, boxy sound of a small old speaker

Broadcast level	Compressor 6:1 from -28 dB	Everything pressed to one loud, even volume
Brightness	Pitch +2, Tone +1	A lighter, more chipper voice than your own

Never stop smiling

Hold a showman's grin for the whole line. The cheer has to stay on even when the words turn menacing; that mismatch is the character.
Use an old announcer's rhythm: quick, clipped, every consonant landed, sentences rolling on with barely a breath.
Punch one word per sentence and glide over the rest, like someone reading the evening programme.
Stage laughter and musical stings are not added for you. If you want them, laugh yourself or play them from a soundboard.

On the set, in the studio, or breaking up

The main clip is the voice as heard through the radio itself. Widening the band to 250–5500 Hz gives the host in the studio, not on the set: fuller and clearer, the better pick for long roleplay scenes where people need every word. The last clip pushes distortion to 0.5 at 70% and adds an 8-bit crusher at 9 kHz, 40% mixed in. That is the broadcast breaking up, for the moments when the character's temper slips. Switch to it for a line or two, then return.
