All excellent replies, thanks to all. Right now I have the vga cable with two loops through a large snap-on of unknown mix (I have just ordered a couple of large 31 mix snap-ons) and placed seven snap-on beads of unknown mix on the AC cable. It looks like the situation is better as it now requires about a five second keydown to freeze the monitor, (not something that happens a lot, just a test.) I tried swapping the small beads on the AC line with a double loop through a snap-on (like the one I now have on the vga cable) but that was much worse.
Regarding keeping RF out of the shack, Don, the 40/80 meter inverted vee has a several looped coax choke at the center feedpoint and the SteppIr vertical has a large DX Engineering one-to-one balun/choke. The Mosley 2 element Yagi has a common mode choke made of a string of beads originally used for a Spyderbeam. The coax feedlines are all between 75 and 100 feet. I will look into more suppression at the shack entrance. And Bryon, I will check to see if the BenQ mounting holes (I am using mounts) are connected to the D-shell. Thanks. ..mike AI6II -- View this message in context: http://elecraft.365791.n2.nabble.com/P3-SVGA-external-monitor-freezes-RFI-tp7594411p7594429.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
