My '94 Chevy Lumina Euro seems OK for HF; I'd planted my Kenwood TS-140 on the passenger seat the other day, and had NO problems. 75W out on 20M thru the cigarette lighter; OK, large capacitor and ferrite torroid on power lines, left over from my '88 Grand Am whose "Driver Information Center" didn't like the 20M band :-). Couldn't even find the "birdies" from the Engine Control Module's uP! The only discernable "noise" is a small bit of hash from the fuel pump, and a lot of hash when raising/lowering the power windows. I suspect a simple LCL Pi filter on the fuel pump harness (near the fuel pump) would take out the noise, but so does the noise blanker on the radio. BTW: Not to make this a big sale pitch for GM, but we do a LOT of RFI testing on our cars to make sure that they neither corrupt nor get corrupted by ham rigs. Stop by the GM booth at the Dayton HamVention and we can talk some more . . . -- James C. Bach Ph: (317)-451-0455 The views & opinions expressed Advanced Project Engr.

To: ham-digital@ucsd.edu Hello Netpeople, I was wondering if by any chance there has evolved some sort of Personal Computer remote control standard for radio and TV equipment, like e.g. the GPIB interface for analogue measurement equipment 15 or more years back. I know nowadays you can buy TV-receiver cards for the PC which may or may not be sufficiently shielded, what I do know is that with soundcards the noise situation can't possibly be bettered without making the product substantially more expensive and I guess this holds for anything inside a PC processing HF and higher frequency analogue signals. Any radio & TV sets out there with GPIB or its successor ? Thanks in advance, Bob. u211321@hnykun11.uci.kun.NL u211321@hnykun11.urc.kun.NL P.S.: please e-mail (as well). +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ------------------------------ Date: Mon, 14 Mar 1994 17:07:51 GMT From: ihnp4.ucsd.edu!usc!howland.reston.ans.net!torn!newshub.ccs.yorku.ca!apogee.ccs.yorku.ca!edleslie@network.ucsd.edu To: ham-digital@ucsd.edu References <1994Mar13.134356.26825@ke4zv.atl.ga.us>, , <1994Mar14.134950.1991@ke4zv.atl.ga.us> Subject : Re: Diesel or Taurus fr HF/VHF mobile??

With *all* electrical systems disconnected, it still made the pseudo-ignition noise. The best guess we could come up with was that the plasma formed by combustion was somehow shock exciting something and causing it to radiate. We considered static discharges due to the rotating machinery, but we bonded *everything*, including finger stock on the crank and cam, and on the injection pump cam, and we put anti-static brushes on the clutch, all without making it go away. So I don't think that was it. It would sit there at idle in the shop and tear up every radio in the place with absolutely *no* electrical equipment operating on the vehicle. A real puzzle.

We've been building diesel engine controllers for many many years. In fact, we've got an engine controller for LP-fueled fork-lifts! And we've got a controller for marine applications; one of them even got submerged (with the boat) in salt-water for 10 weeks, and after they dredged-out the boat (and cleaned-up the engine) the engine started on the 1st-crank with THAT controller. But I digress. There are several diesel models with computers controlling the electronically controlled transmissions! And what about the instrument cluster, CD player/Radio, etc.? -- James C.
