Yesterday afternoon I did an experiment with a friend's CRT SS-6900n (v6), into a TinySA spectrum analyser and oil can dummy load.
The test was just radio power and 50dB attenuation between the rig and analyser. On AM and FM, the signal appears to be clean. However, when switched to either USB or LSB, there are spurs that appear between 2.5MHz to 3MHz above and below the fundamental.
