After you've done your build, you are encouraged to put into use and report your distance of QSO with a screen snapshot of the software (WSJT-x or JTDX) in this thread. The longest distance QSO so far was made by BG7IKK with an Italian station and the distance is over 9000km with his 20m D4D, per his report in D4D WeChat group.
The contest will be quarterly based and the first place will be awarded a D4D kit. As this quarter ends soon, the first contest ends September 30. I wish to continue the test in Q4 and will send total 2 free kits this year. Wish you good luck.
