    Hello,

    Do you want to make it with discrete components?
    What is the frequency range?

    Usually done with a very large rotary switch in a metal box that has a lot of shielding plates inside to keep cross interference down.

    As Bertus asked - what frequency, power level (if used on a transmitter) and are you wanting it electronically switched or just what us old ham radio operators used to use?

    I interpret SP4T as "Single pole, four throw"

    Rotary switches are the typical way to go with either make-before-break or break-before-make configuration, but I've also seen multi-throw slide switches.
