how do you make a RADIO reciece higher frequencies?

Question

does the variable capacitor (is the tuner) need to be at a higher capacitance so it recieces higher frequencies

Answer 1

No, the variable capacitor would have to be at a lower capacitance. The TRF (tuned radio frequency) stage before the mixer would need to be rebuilt to work at higher frequencies (and reject a different band of image frequencies) and the local oscillator would have to be rebuilt to operate at a higher frequency as well so that the hetrodyned signal would be at the correct IF (intermediate frequency) for the radios IF amplifier to amplify.
