Initial Tests, Using Your AA7 | Ramsey Electronics specification

24. BEFORE connecting battery or conducting any tests, PLEASE recheck each of the preceding steps, looking especially for:

•quality of solder connections

•correct orientation of Q1 and Q2

•correct orientation of the electrolytic C4

•correct battery wire polarity

•correct values for resistors and capacitors

INITIAL TESTS

No adjustments or alignment is required. See the following section about preparing a reliable and convenient cable for the AA7 and your receiver as well as an optional add-on antenna.

Testing the AA7 consists of turning it on, using it and checking that all its described features are operational. You will need to become accustomed to the signal strength in the highest range of the gain control. If you experience any problem, consult the Trouble-Shooting Hints section of this book.

USING YOUR AA7

For some of our kits, this "USING...." section becomes the longest part of

the book, depending on the possible applications of the kit product. What is very nice about the AA7 is that using it is simple, enjoyable and immediate. We have two suggestions that will increase your enjoyment of the AA7 right from the beginning:

1. Prepare a reliable coaxial cable with the right connectors to run from the antenna input of your receiver or scanner to the RF output of the AA7 (RCA male plug required). If you do not have them at hand, a visit to Radio Shack should easily get you what you need.

2. Make a simple "supplementary portable antenna" of any design which is practical for YOU. Use a small-diameter coaxial cable neatly terminated in a male RCA male plug to mate J1. This antenna can be a dipole, or random wire with earth ground or counterpoise, a bigger vertical whip of some kind, a Slinky, or even a pair of alligator clips at the end of your coax line, ready to be clipped to any large metal surface that may be handy, from screen doors to bed springs! This accessory for your AA7 will help you explore the truth of "Ramsey's Antenna Rule" in a variety of travel situations: "If you want more signal, put up more metal!”

A Caution to Ham, Maritime and CB Operators:
