Slow Scan TV (SSTV)

I have been a licensed ham for only three weeks now, but I have already participated in digital forms of transmission via SSTV. With the help of the members of the Wellington Radio Club past Sunday, June 15, 2008. I received and transmitted my first slow scan television pictures via the 2 meter Wellington radio club repeater @ 147.285 (+).Some examples of what I received:

Scott AF4KK the net operator of the weekly slow scan net, held every Sunday at 7:30 on 147.285 repeater helped me in seting up the proper programs to make this possible.

Title MMSSTV:

The program can be found @ http://mmhamsoft.amateur-radio.ca/mmsstv/
It is free as long as it is not used for commercial purposes.

Background Information:

Slow-scan television (SSTV) is a picture transmission method used mainly by amateur radio operators, to transmit and receive static pictures via radio in monochrome or color.

A technical term for SSTV is narrowband television. Broadcast television requires huge 5, 6 or 8 MHz wide channels, because it transmits 25 or 30 pictures per second (in the NTSC, PAL or SECAM systems), but SSTV usually takes up to only 3 kHz of bandwidth. It is a much slower method of still picture transmission, usually lasting from about eight seconds to a couple of minutes.

Since SSTV systems operate on voice frequencies, amateurs use it on shortwave (also known as HF by amateur radio operators), VHF and UHF radio.
