    How can I make a miniaturized oscillator (146 MHz) bug to be hidden for Fox
    hunting practice. If the bug gets damaged or lost, it will be at a minimum
    cost. Are there any schematics aailable? Thank you.

  3. One way might be to use a can squarewave osc at a 3rd of 146MHz
    (48.66MHz).... and use a 146MHz bandpass filter to only select the 3rd
    harmonic of 48.66MHz then a power amp to bost.

    But this just a carrier...

    Made one way back for checking the receiver. I hunted down a standard
    frequency crystal whose nth harmonic was close to the fox frequency,
    somewhere around 146 megs. Just a simple oscillator feeding a 146 MHz tank
    circuit provided quite enough power for it to be detected a couple of
    hundred metres away.

    I'm surprised that foxhunting hasn't gone up-spectrum. A 75cm directional
    setup on a vehicle is a lot less messy than 2 metres.
