I was chatting with a club member this weekend. He told me about a digital slow scan tv modulation mode designed for use in the HF bands on a typical SSB bandwidth.
I know about analog slow scan television and have heard about many binary transfer methods for HF. This was the first time I heard something coined “Digital Slow Scan TV.” The program is called Easypal and can be found easily via a web search.
There appears to be a dedicated team behind this program which suggests a healthy development effort.
Indeed, after downloading the program and installing it on a Windows XP system, I was using it in no time. My friend was on the local repeater at the time and guided me through appropriate default options to use.
