    Hi,
    I just registered, but have used this website for a while.
    For school, i am building a 2 band super regenerative receiver, and the band switch must be on very, very short leads. That is inconvenient for the enclosure i am using, so i need an alternative. i was thinking maybe a relay or transistor switch.

    The use of the switch is to switch on a second gang on a variable capacitor, so it pretty much needs infinte resistance or 0 Ω resistance.

    Any help would be appreciated!

    Thanks!

    It should be straightforward to switch in an extra cap by the help of a diode. Look at how diodes help in schematics for bandswitching in the Heathkit HW-8 or the receive/transmitcircuitry in a Kenwood TS-120 (the latter is much more clever but it is basically the same use of a diode).
