No, it was a spurious emission from something but I'm not sure what. My latest experiment of playing with L34 and SG is much cleaner: http://tinyurl.com/26hfrb AF Gain was set around 2-o'clock with very little gain on the line input level of the sound card as shown here: http://tinyurl.com/2dzho4 I can get rid of the noise completely as spectrogram sees it but the signal drops about -25 dB. I hear white noise along with the signal when spectrogram sees nothing. -- JT Croteau, N1ESE - Manchester, NH _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
