> You can verify that it is line noise by receiving it on AM and putting a > scope on the audio. The 60 Hz period sticks out like a sore thumb. Is there any software available that allows you to use your soundcard as a scope? I can see what appears to be 60 cycle noise in the display of MMTTY but since there are no calibration marks I can't be sure. Any ideas for software? 73 Jamie WW3S
