![]() So, with digital modes, what you are doing is basically sending sounds from your PC through your transceiver out onto the airwaves. Let me see if I can explain, and maybe that’ll help the next guy. It took me a few days of tinkering to figure it out, and then I started to try to figure it out from a holistic system perspective. A lot of hams had posted their settings, but unless you had the same radio, same operating system, same cable, they weren’t always helpful. ![]() The problem with digital modes was getting started. Truthfully, it very well might have saved my interest in ham radio, which had largely become an exercise in frustration. With WSJT-X, I’ve been communicating around the entire Pacific rim on 50 watts or less, typically much less. If you are, like most hams, antenna constrained and power constrained (100W to a dipole for me, on a city lot), these digital modes are a god-send, because I can barely get people in the next state to hear me on sideband with the declining solar cycle going on. ![]() Available for Windows, Linux, and Mac, it is available here. The WSJT-X software package allows ham radio operators to use those protocols easily. Originally for EME (Earth-Moon-Earth) bounce communications, they’ve since found a role in HF communications. Joe developed a series of weak signal communications protocols for radio. I’ve never met Joe Taylor (K1JT), but I’ll confess to having very strong feelings of gratitude toward the man. ![]()
