Overview of FLDIGI and Digital Modes of Communications

On 5 June 2012, Charles Hargrove, N2NOV, of Staten Island, provided the NYC-ARECS team with a hands-on overview and demonstration of various digital modes of communications including Fldigi. A total of 13 members (and three guest), spent 90 minutes learning to setup their computers for digital communications and even exchanged messages across the room via digital signals / via the computer sound boards. Fldigi is a computer program intended for Amateur Radio Digital Modes operation using a PC (Personal Computer). Fldigi operates (as does most similar software) in conjunction with a transceiver, and uses the PC sound card as the main means of input from the radio, and output to the radio. Fldigi is an additional mode in of which communications can be conducted during an emergency, it can be used to send "email" messages (via the radio), as well as images.
