Bob Heil is the leading developer and manufacturer of ham radio audio components (microphones, headphones, etc.). He is also a leader in the research and development of commercial audio equipment.
Bob will demonstrate in real time how voice sounds are captured by microphones, how the quality of the microphone affects the transmitted signal, and how the transmitted signal is reproduced.
Based on the quality of the equipment he convinces you that “A microphone is not a microphone” unless properly designed.
He also demonstrates how headphones can enhance the intelligibility of the received signal.
This will be one of the best ham radio technical presentations we’ve been fortunate to host.

Join us on Zoom to participate in social time starting at 19:00
