Thanks for your input Jim. I attended your talk at Pacifcon and have been implementing some bonding improvements including tying all the earth ground rods, tower etc. with #4 wire as well as better equipment grounding in the station.
The beads on the power cable (only 110v AC no DC) appear to have improved the situation, but I understand it would be better to use multiple turns though a ferrite core on the VGA cable. Without clipping and re-wiring the end connector I have not acquired a big enough ferrite core to do the job. The BenQ does not appear to generate any trash at least to the level I notice it in my operations. At Pacificon, you did suggest a way to connect the monitor's DB-15 connector to the station ground through the small screws that hold the cable connector in place. I might try that. Tnx es 73 ..mike AI6II /Probably yes. Perhaps a bad cable between the monitor and the P3. Beads on cables do not solve problems with HF RFI. Multiple turns through a bead or core are needed. Study k9yc.com/FRI-Ham.pdf A neighbor ham gave me a Samsung monitor that has very bad RFI susceptibility, and it also generates RF trash. It runs on 12V, but running from a 12V battery does not help, and I've not been able to solve it with chokes. RF coupling is via internal wiring and poor shielding. 73, Jim K9YC / -- View this message in context: http://elecraft.365791.n2.nabble.com/P3-SVGA-external-monitor-freezes-RFI-tp7594411p7594417.html Sent from the Elecraft 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:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
