A afternoon on shortwave with WSJT-X. That software is similar the WSJT software we use on EME and is also made by K1JT. Additional to the VHF version this short wave version has a OMNI RIG connection for CAT and an adapted for shortwave operation surface. It’s easy to work the whole world with little power and a wire in the backyard..
Note: I am not the programmer of this software I only present it. For any help with this software please contact the manufacturer).
