  • GRID DIP METER DESIGN makearadio

    Dip oscillator This is the main part of the instrument (many different configurations are used in practice) is a very basic Colpits RF Oscillator using a VHF/UHF transistor (An MPSH10), although any similar transistor could be used. If another is used you may have to play with the R4 C8 and R3 values to obtain reliable oscillations.

    work at 400 (not 440!) MHz. Most dip meters are lower 200 MHz or less. In an older ARRL Handbook, I found a grid dip meter using a Nuvistor 6CW4 circuit good to several hundred MHz. It's interesting that it's hard to beat a vacuum tube for low input capacitance. The 6CW4 boasts a fraction of a pf for grid
