I'm about to build a 386SX 20 Mhz system by purchasing components mail order. My concern is minimizing RFI from the system, thus I feel I should at least get close to FCC Type B limits. When purchasing a cabinet/power supply separate from the motherboard, how can I tell what manufacturers components will minimize the RFI? If this can't be determined, I figure I can buy a bare-bones system with motherboard, case and power supply that is already Type B accepted. Does anyone have any recommendations? What case/motherboard have you bought that can minimize RFI? -- ---------------------------------------------------------------------- Ken Roser - WA2VCI - mtgzy!ker - AT&T Bell Laboratories - 908-957-5822 ----------------------------------------------------------------------

Not that I'm a scofflaw, but the FCC B regs are for worst case, and unless you are operating in a situation where you have *unusual* concerns with RF, there will be no problem. I listen to shortwave and TV in here, in a room which often has two 386's and an XT running. Both 386's are running (at the moment) with the covers open and nothing. My bedroom TV is about four feet from one system separated by an interior wall. No problem, and she has low tolerance for interference. -- bill davidsen - davidsen@sixhub.uucp (uunet!crdgw1!sixhub!davidsen) sysop *IX BBS and Public Access UNIX moderator of comp.binaries.ibm.pc and 80386 mailing list "Stupidity, like virtue, is its own reward" -me

The worst offender is my multisync monitor (and cable). Bill Brothers N6ZPC billbr@xstor.COM
