Communication through Pictures
Early morning finds me sending and receiving SSTV picture transmissions, you know what they say...."one picture is worth a 1000 words!"
If your not familiar with SSTV (slow scan television), it is a picture transmission method used to transmit and receive static pictures via radio, whether that be your favorite dual-band VHF/UHF transceiver, or possibly your HF rig.
A literal term for SSTV is narrowband television. Analog broadcast television requires at least 6 MHz wide channels, because it transmits 25 or 30 picture frames per second (in the NTSC, PAL or SECAM color systems).
SSTV usually only takes up to a maximum of 3 kHz of bandwidth. It is a much slower method of still picture transmission, usually taking from about eight seconds to a couple of minutes, depending on the mode used, to transmit one image frame.
In this photo I am using a Kenwood VC-H1 interactive Visual communicator paired with the Kenwood D72 HT positioned in my radio chest harness, and connected to my 2 meter take-down tape measure yagi to send and receive SSTV images on 145.5 MHz, the FM SSTV simplex frequency.
For more information on the VC-H1 and what I plan on using it for, check it out here.....
