Build an Emergency Radio Kit Plans
These free plans will guide you to convert a classic home radio to receive shortwave transmissions.
Here is the most inexpensive route to short-wave
listening—the conversion of a table model radio.
JUST above the broadcast band exists the bustling activity of
various communications services. A sweep across the dial
from 1.7 to 5.5 mc will tune ship-to-shore stations, commercial
telephone, weather, WWV time signals, and the 80 meter
With little expense or special skill a table model AC-DC radio
can easily be converted for use on these frequencies. The cost
may be kept below $4.50 even if all the parts are purchased new.
Here's how it works. The tuning range of the home receiver is
altered by replacing the antenna and oscillator coils and tuning
condenser. The parts are readily available from local distributors
or mail order houses.
Alignment, described later, is accomplished
with signals received off-the-air.
The converted receiver may be used with its original speaker. However,
headphone reception, valuable for receiving weak stations, is provided for.
