First one on the table was the Tracer/Injector kit. Here is their product description from their website.
The Hendricks Tracer/Injector probe is an easy to use, handheld, piece of test equipment for diagnosing amplifiers, receivers and transmitters. It incorporates an LM358N, integrated circuit, half of which is the audio signal injector and the other half a tracer, incorporating a product detector to allow you to locate problem stages. With this tool you will be able inject audio signals through the various stages of your problem circuit, or trace signals from the front end thus narrowing in on the problem. It is a completely self contained, handheld device, using an inexpensive readily available battery.
I got started this morning and before I knew it, it was finished. Yep I forgot to take pictures until after I put on the final shrink wrap tube.
The whole thing is encased in shrink wrap tubing, but you can put it in your own case. A quick test with an earphone verified it was working.
Next up was the R.F. Probe kit.
A brief description again from their website.
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 meg ohm 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.
Assembled board with components.
I comes with copper tape that you wrap around the PVC tubing that acts as shielding.
Completed probe. The hardest thing about this kit was putting the screw through the PVC tube body and aligning it with the nut on the PC board. Both of these were simple projects perfect for killing a little time in the shack. I am sure I will get good use out of both of these tools.
