4. Write down five of the most important "Q" signals, and give the meaning of each.

5. Draw from memory, using correct symbols, the circuit diagram for a low power, short wave transmitting set, and describe briefly the principal pieces of apparatus required. Describe each part of the apparatus, and explain how its works. Explain how to use a wave meter in connection with transmitting apparatus to secure the proper wave length of radiation.

6. Draw from memory, using correct symbols, a wiring diagram of a complete receiving apparatus, using a vacuum tube detector, fixed and variable condensers, resistances, batteries, phones and ground. Describe each part of the apparatus and explain how it works.

7. Describe a vacuum tuber, name some of its possible uses, and show a diagram for one of them.

8. Explain the difference between continuous wave, and modulated or interrupted continuous waves.

9. Construct with his own hands a practical working receiving set, and demonstrate its operation for receiving signals from a station 25 or more miles away.

10. Explain how to install an antenna, how to connect it to the sending and receiving set, how to ground it properly and how to protect it against lightning, and power wires.

NOTE.--The holding of a first grade amateur operator's license and a regular or special amateur station license will exempt the holder from examination on counts 1, 2, 3 and 4. Both the operator's license and the station license must be presented before the local Court of Honor and shown to be in force at the time the badge is awarded.
