We always give practical demos, but, here as audience was heavy user of CW & RT from police dept. we didn't give demo of that kind hi..hi.., but surely gave demos of Digital Communication - sending text messages between two VHF Setup and second demo of sending SSTV Images between two local vhf stations! For audience it was interesting to learn how we ham convert simple ASCII codes to corresponding audio frequencies (for Digital Communication) and RGB pixel values of Image to Slow Scan Television format to transmit & receive 'IMAGES' via our standard radios! That's why we proudly say to be Ham Radio as an oldest Social Media!
