Organizing a Resistor Collection

A simple, yet effective way to organize your supply of resistors is found in last years parts catalogs, For years I had all of mv resistors thrown in a box, each time 1 needed a particular value I had to rummage tlirough the entire box to find it. The answer to this problem lies in a small cabinet with twelve drawers* Thumb through last years catalogs to the resistor section. Cut out the table ot standard values. I used the IRC 10% table from Allied Radios catalog- The 5% table would provide a more complete listing, but it may be too large to fit the drawer fronts. You will note that the table is divided into twelve columns, cut these apart and glue or tape them to the fronts of the drawers. This simple system saves 903? of your resistor locating time, looks neater, and helps you keep a balanced supply on hand,

2) Dial Calibration—Generator Mode switch to 1 MHz, Generator output to receiver antenna input, and adjusted to suitable level. Adjust receiver trimmers for markers at 1 MHz dial markings.

3) RF Alignment. Generator Mode switch to NOISE. Generator output to receiver antenna input, Tracer input to receiver audio output Generator level control full clockwise- Tracer gain control set for suitable VU meter reading. Peak rf and converter stage trimmers for max noise level on VU meter.

Many other uses for the Gentrac will suggest themselves. The tracer is conventionally used for locating signal loss or distortion, using the appropriate probe, when receiver trouble shooting.

With a telephone pickup coil plugged into tracer input #1, you can have a handy telephone amplifier. And for a little code practice, patch the generator output to (lie tracer input, plug a morse key into J2, and set the Generator Mode switch to af. When used as a practice oscillator square wave output may prove less fatiguing than sine wave, and you can adjust the af frequency to your own iking. IncidentIv J2, which keys the af oscillator, is mounted on the back of the minibox, and may be excluded if not required.
