Question: R.T.U. asks: Can you straighten me out on a question that has been bothering me. What is the difference between short and long waves? Why can one receive short waves over a greater distance than long waves? Answer: The wave length is determined by the measurement of a wave in meters (a meter being about 37 inches). The short waves travel farther because they are kept from leaving the earth and are reflected back by what we know as the "'Heaviside Layer." The long waves are absorbed and lose strength during reflection when they come in contact with this laver. Question: R.N.B. asks: What can be done to stop the interference caused by automobile ignition on my automobile radio? Answer: The set should be completely shielded and grounded to the frame of the car. Then a good make of suppressors attached to the spark plugs. If this doesn't help, have an ignition expert look it over. Question: L.S.D. asks: Is there any simple way to tune for stations on a short wave set? Answer: Tuning on a short wave set is as simple as tuning on an ordinary receiver, but the dial must be moved very slowly or many distant stations will be passed over. Tune in every signal, no matter how weak. The signal will in most cases turn out to be of sufficient strength to be enjoyed. Always log every station heard and its frequency. Then try tuning in a station near the same frequency. After you have logged two or three stations, any other one with a frequency falling between those logged will come in between them on vour dial. Question: D.L. asks: Does a person have to be a licensed amateur operator to use a short wave receiver? Is there anything on short wave of interest to the average person? Answer: It is the privilege of anyone to enjoy the many wonderful programs now being broadcast on short waves. Most of the large stations of the world broadcast their regular programs on short wave relay stations. A great many of the foreign stations broadcast only on short wave. Best reception is heard when it is night at the transmitting station. Question: P.G.S. asks: Is it within the law to receive the police broadcasts? If it is permissible, should I have my set rewired or what method should I use? > I have a seven-tube set. Answer: I would not advise having the set rewired. There are many devices on the market for this purpose. The adaption of these devices is a simple task, but should be done only by a competent radio technician.
