Even without an input (antenna QRN or a noise diode) you should see the noise from your sound card's ADC. Nothing at all on the plot equates to me to the settings being off, so I suggest patiently following N0SS's instructions on EVERY setting.
Also understand that the Spectrogram does need to know which input (line or microphone) is getting the audio, and you need to adjust the 'audio slider' your PC provides in 'software.' It may not be your OS - but I myself still use XP. 73 Curt ----- Original Message ---- From: John Cooper <w...@gt.rr.com> To: elecraft <elecraft@mailman.qth.net> Sent: Wed, April 13, 2011 8:50:58 PM Subject: [Elecraft] spectrogram no signal OK I finally downloaded the free spectrogram ver 5.17 running on windows 7 it comes up set like on NOSS site says too have a noise generator hooked up to antenna.
