I was testing my Morse Code transmitter last night by sending a CQ on 7.102 MHz using various transmit powers ranging from 5 to 10 watts QRP, up to 100 watts full power, using an ICOM 718 and a home-brewed antenna. It appears that 4 stations (one in the Pacific and 3 on the other side of the world—in the US) heard my signal, as reported in the Reverse Beacon Network (an automated system that receives and logs Morse code transmissions).
While this is probably the farthest distance to date that my signal was able to reach, this is just one-way communication. Probably as I improve my antenna, I’d also be able to hear the faint signals coming from the other side of the world.
