The ARRL/FARS/PAARA ham radio demonstration of Radio and Modulation. We showed AM/SSB/FM analog modes and PSK31, MFSK, RTTY, Hellshreiber, Olivia, and other digital modes using Yaesu FT-817, Elecraft K2, Softrock and SDR-IQ on 10 meters with dummy loads and with mic and audio decoding. QR codes lead visitors to MP3 sound clips of modes which were recognized with FC6TE's RSCode and decoded using FLDigi on Windows, Linux, and Mac.
