1. [RFI] Interfacing to sound card RFI (score: 1): Author: Palomar@compuserve.com (Palomar Engineers); Date: Tue, 20 Nov 2001 18:17:13 -0500; One possibility is too many turns on the -77 toroids. Capacitance across winding can leak the signal. For 20 meters try 5 turns closewound. Keep winding ends apart. Worth a try anyway -- Jack, K6NY,; /archives//html/RFI/2001-11/msg00018.html (6,744 bytes)
2. [RFI] Interfacing to sound card RFI (score: 1): Author: jon.ogden@cain-forlaw.com (Jon Ogden); Date: Mon, 26 Nov 2001 09:29:05 -0600; WOW! That's a new one. I never thought you could have too many turns on the torroid. I guess it makes sense, but I've always been told that the more turns you can get around one of those, the better; /archives//html/RFI/2001-11/msg00020.html (8,085 bytes)
3. [RFI] Interfacing to sound card RFI (score: 1): Author: eedwards@oppd.com (EDWARDS, EDDIE J); Date: Mon, 26 Nov 2001 11:33:29 -0600; I have a question on this. I'm sort of thinking out loud here. Are you trying to reduce distributed capacitance of the coil or increase it? First, by winding the coil "closewound" you would be increa; /archives//html/RFI/2001-11/msg00021.html (10,831 bytes)
4. [RFI] Interfacing to sound card RFI (score: 1): Author: Palomar@compuserve.com (Palomar Engineers); Date: Mon, 26 Nov 2001 22:49:02 -0500; Ed, K0IL is correct. Turns should be spaced, not close wound. However, be sure that beginning and end of winding are separated by about 1/5 of the core diameter or so. Yes, you can get enough distrib; /archives//html/RFI/2001-11/msg00022.html (6,933 bytes)
