On this movie, made by WA3LTB, you can watch how things work with JT65A, part of the WSJT software by K1JT. It's a way to make QSO's on HF using JT65A mode. In most of the cases you have to make a sked for making a QSO. You can use Hamspot.net for this purpose. A new manner for working QRP. With WSPR I was reported by W3GXT (6109 km) and W3HH (7285 km) on 30 meter.
