It's called a "Sucker Stick Transmitter" because the loading and antenna coils were wound basket weave style on penny sucker sticks back in the 50's.
The little transmitter is also some times called a "Slat Board Transmitter" because the chassis was made from slats cut from orange or apple crates.
TRANSMITTER
The transmitter is a simple one tube design using a 6L6, or a 6v6 tube. Either will work in this circuit. The 6L6 puts out about 8 watts, the 6v6 about 4 watts.
The transmitters frequency is controlled by selecting the proper crystal for 80 meters or 40 meters.
The reason for crystal control is to insure operation of the transmitter on assigned ham frequencies.
With the correct crystal plugger in and the correct voltages on the tube, along with the proper wound loading and antenna coils, all connected to resonate antenna, a new ham could make many contacts far and near.
RECEIVER The receiver is a simple one tube Regenerative receiver.
The 3s4 tube and parts make up the very minimal receiver
a person can build.
Voltage needed for the receiver 22 1/2 volts d.c. and 3 volts for the filament.
POWER SUPPLY The power supply takes the a.c.voltage in your house, steps it up through a transformer, converts it into direct current through a rectifer tube, and then "purifies" it by means of a filter choke and two filter capacitors.This pure dD.C. current is necessary for your plate supply to insure a clean sharp signal.
Transmitter voltage requirments 300 volts d.c. @70-ma, 6.3 volts and 5 volts, all supplied by this power supply.
