I first used Spectrogram on a cheap, POJ Gateway laptop I bought when I retired and turned in the company's laptop. I had noise in the display sufficient to mask the audio being fed in from my K2. I tried bonding the K2 and laptop grounds together, grounding and ungrounding, and was about give up when I unplugged the laptop power. Noise totally went away. If you're on a laptop, it would be worth a try. I no longer have the Gateway. 73, Fred K6DGW - Northern California Contest Club - CU in the 2009 Cal QSO Party 3-4 Oct 2009 - www.cqp.org ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
