— Extract from letter in our files.
The above unsolicited letter is from a satisfied user of a short wave set built around Aero Coils. This receiver was located in western Pennsylvania, and with two stages of audio, loud speaker reception was obtained about three days a week.
While such results are not to be expected from every receiver, it is a fact that with a given amount of power, a broadcasting station can be heard at far greater distances when transmitting on short Waves than in the usual broadcast band. This fact has been responsible for the tremendously increasing interest in short wave reception by radio fans. Static is much less objectionable on short waves and their use has made possible, for the first time, summer reception in many parts of the country where the seasonable decrease in signal strength and increase in atmospheric disturbances has heretofore rendered the summer use of a radio receiver very unsatisfactory. _
Most of the short wave receivers which have been made available to the public up to the present time have been designed primarily for the reception of continuous wave code signals, and have been more or less unsatisfactory for the reception of musical programs, and we believe that Aero shortwave receivers are the first ever placed before the general public which have been designed primarily for the reception of broadcast programs on short waves. The Aero International will give you real thrills. Price of Kit No. 8 complete, $55.30. .
Ask your dealer or jobber for a complete Kit of all parts for the Aero International. If he can t supply you, write us, giving his name.
