I see a number of lines on my Argo QRSS600 screen. But I am not certain what or who it is. The SPM-30 also generates a spur on the frequency it is tuned to! I see also that the noise level is getting higher. So, it is not the best option to listen on 8970 Hz. Tomorrow I will try it with the antenna directly connected to the sound card. Have you a SpectrumLab usr file for VLF? And what version of SpectrumLab should I use? 73, Roelof, pa0rdt
