This morning, for the first time in a while, I was using Rocky with my 20M SoftRock. Imagine my surprise to see a large and varying hump around the local oscillator frequency. I set Rocky for USB and tuned to the LO frequency, and voila - the Chinese shortwave service, in English!
With my ordinary receivers, I cannot hear this signal at all, so I presume it is some sort of mixing product. It is definitely coming in over my antennas, but aside from that I have no clue. Can anyone suggest what might be causing this? As a PS, I am also seeing an AM signal on 14010, broadcasting music, but that one looks normal on the bandscope, with a carrier and sidebands. I can hear it on both ordinary radios. I have not heard it identify so far. 73, Pete N4ZR
