More interesting findings: I disconnected the coax cable to the DVR: RFI is still there! So the cable coax+DVR does not seem to be the source of my RFI on 20m.
With the coax cable disconnected, but the DVR still connected to the TV via HDMI cable, the RFI is there if I'm playing a recorded show to the TV (in other words, data on the cable), but vanishes (no RFI) when I "stop" the DVR (no data being sent to the TV). In both scenarios, the TV is on, coax cable disconnected. This suggests to me that the source is indeed the DVR and it's generating RFI on the HDMI cable. BTW, my cable service is Time Warner Cable (TWC), the DVR is a Samsung provided by TWC. 73 N5BCN - Brian ----- K2 #6800 KSB2 KAT2 KIO2 K160RX KNB2 -- View this message in context: http://elecraft.365791.n2.nabble.com/LCD-TV-Causing-RFI-tp5973980p5975933.html Sent from the [HAM] mailing list archive at Nabble.com. ______________________________________________________________ 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
