The WARC 18 MHz (17 m) band can give surprising results.
I was amazed that my 5 Watt WSPR signal on 18.106 MHz reached Japan this afternoon.
JA2KCT, Ryosei Aimiya from Shimoina picked up my small signal. QRB was an estonishing 9269 km.
In the past I have made a couple of QSO's with Japan but it is certainly not a regular DXCC and therefore for me a special event.
Domo Arigato, 73 !
