Crystal radio The set uses two 1/2 inch by 4 inch #61 Ferrite rods separated
one inch center to center for the coils. The main tuning coil is wound on the
top ferrite rod with 100/46 Litz. The unloaded Q of this coil is 760. The
regeneration feedback winding and the antenna winding are at opposite ends of
the lower rod and are wound with #24 copper. The windings on the lower rod are
wound on sleeves that allow moving them independently across the rod to vary the
coupling |

CRYSTAL SET RADIO Make a working portable AM radio without batteries Crystal Radio with Loop Antenna, Make a working
portable AM radio without batteries. The shortwave bands provide entertainment
and news for millions (perhaps billions) of people around the world. One BBC
estimate I heard claimed that 100 million short wave radios sets are in use
around the world! Outlined below are plans to make a shortwave crystal set radio
that (with a good antenna and earth connection) is capable of receiving stations
from around the world |
