Transistor Amplifier and Waveform Exploration Board

By Mark Spencer, WA8SME
ARRL Education and Technology Coordinator
April 21, 2005

The transistor amplifier and waveform exploration board can be a very flexible instructional resource for teachers and ham radio instructors. The utility of this activity board goes beyond its intended purpose; introduce students to fundamental waveforms and allow students to explore the transistor as an amplifier. Some of the lesson suggestions for this board include:

The board kit includes the board, parts to populate the board, and CD-ROM with construction manual and lesson suggestions. A Volt Ohm Meter (VOM) and oscilloscope are required to take full advantage of the board.

The circuit can easily be duplicated and hand wired on a prototyping board. The components are not critical and can be obtained from electronic parts suppliers. A parts list is included in the board documentation.

Schools and teachers can obtain board kits (while supply lasts) by submitting a letter of request on school letterhead to the ETP coordinator, Mark Spencer, WA8SME, at ARRL HQ.

All hams are encouraged to duplicate this project and add the board to their learning/instructional portfolio. The following links allow download of relevant files:
