RF Probe Kit
The Hendricks R.F. probe is a handy test device to have in your shack. When
used with an inexpensive high impedance digital voltmeter (typically 11 megohm
input impedance), you can measure RF voltage in your solid state circuits, and
trace RF through your new designs or malfunctioning circuits. You will be able
to detect RF voltages in the range of .25v to 50v, and accurately measure
voltages in the range of 1.0v to 50v, the range of the 1N34A diode used in
this design, well up to 30mHz. This design is shielded to prevent picking up
unwanted stray signals, or broadcasting them to other stages while testing.
The kit is a complete set of components, and detailed assembly instructions
are on-line. All that is needed are the usual kit assembly tools.
