PS: On your VLF spectrogram, it would be useful to enable the spectrum as well. Normally you should see the Alphas at 20...30 dB S/N. But they are covered by the very equal noise floor. Wow many dBs does the noise floor drop when you disconnect the antenna from the soundcard, or disconnect the power supply? 73, Stefan Am 26.03.2012 20:33, schrieb PA1SDB, Peter: Hello Stefan, Loud and clear here in Appingedam, JO33kh http://www.qsl.net/pa1sdb/ I use that Mini Whip I was writing about a few times last week. 73's, Peter - PA1SDB Mini Whip @ 4 meters above the ground and Alinco DX70 rtx. |
