The type of antenna you ll want to use for your shortwave receiver depends on the degree of interest you have in shortwave listening, on whether you are limited to an indoor or balcony antenna If you cannot use an outdoor antenna, you can make yourself a whip antenna from telescoping radio antenna from your local Radio Shack store A better antenna would be to throw a 10 to 20 foot piece of insulated wire out the window, secured to a pole or tree away from your window You could also place a length of wire in your attic to act as an antenna An even better antenna would be a dipole antenna cut for the desired radio band of most interest In order to construct your own dipole antenna, you can refer to the diagram depicted in Figure 8-5 Simply use the formula: 468 divided by the frequency in Megahertz for example If you wanted to construct a dipole for 7410 MHz, you would divide 468 by 7410 The results would be 63157 feet, so one-half of that number is 315 feet Each leg of the dipole antenna would then be 315 feet If you do construct your own dipole antenna, you should keep the antenna away from metal objects and use insulated wire and be sure to keep

Shortwave listening is a fun hobby for young and old alike Once you have your antenna all set up, it is time to begin listening to your new radio The chart in Table 8-4 illustrates the most common shortwave bands and their shortwave frequency in Megahertz vs their wavelength in meters Many times the shortwave bands are referred to in meters, such as the 40 or 80 meter band, so this chart will help you see the relationship between the two As a shortwave radio listener, you will want to know what International broadcasters are broadcasting when you have time to listen to your new radio Most people have spare time in the evening for

their hobby So you will want to know which bands are best for night time use, and who is broadcasting at that time Refer to the chart in Table 8-5, which illustrates the broadcaster and their frequencies, etc Usually the best shortwave bands, for evening use are the lower frequency bands such as the 40, 41 and 49 meter bands Use this chart or check on the Internet for the latest shortwave listings Have fun!

If you experience difficulty, think of your receiver as consisting of several sections or stages: oscillator-mixer, IF audio and AGC, and final audio output (LM386) The first step in case of problems is to make sure that the tunable oscillator is working, which can be done by listening for its signal on another receiver After the oscillator circuit is confirmed as working, standard signal tracing procedures should isolate any problem, which will be either an incorrectly installed part, a defective part or a bad solder connection Correct orientation or polarity of all diodes, transistors, electrolytic capacitors and ICs is essential Problem: Strong shortwave broadcast audible throughout tuning range

Solution: This can occur if your antenna is too good or if the RF Gain control is turned up too high The high sensitivity of the front end is designed for simple antennas, with most reception quite satisfactory with only 25 feet or so of wire Problem: Local AM radio station audible throughout tuning range Solution: Whether this will even happen depends on how close you are to a local AM station It is very important that all component leads be as short as possible, since just a bit of wire can help D1 and the several stages of audio amplification give you a free, unwanted classic crystal radio A grounded metal case for the SR2 is one possible solution
