Right. It is interesting to look at the carriers from various broadcasting powerhouses on HF. Sometimes they spread out 10-20Hz or so, sometimes the same stations produce a thin line on the spectrogram. Longer paths seems to produce wider traces, as expected. It all depends on the mood of Mr. Doppler who seems to depend on the mood of the Sun. 73 Johan SM6LKM
