A new RFI (Radio Frequency Interference ) source appears on the 80 M ham band in the area due to a Boat Battery Charger. Video: recorded 3-31-2011 Previous experience with a ‘Guest’ brand battery charger (rated FCC Class B – for use in Industrial/non-residential areas) with a next door neighbor helped me identify this source. Address: 705 Roaming Road Update 6-23-2011 – boat and noise has returned: www.youtube.com Related – How to DF noise – Technique using portable SW radio, titled: “Radio Direction Finding (RDF) with portable radio on arcing” www.youtube.com .
Part 2 A good theory demonstrated with regard to Toyota’s Unwanted Acceleration and the need for the FCC to revisit who and what Part 15 rules apply and standards going forward in the new mobile digital video and broadband plans. Lives are clearly at risk as the number of mobile RF transmitters doubles every 2 years and more micro-controllers are in charge of devices that could be life threatening if interfered on.
While looking-up many items in the presentation in wikipedia, I see exactly what you are speaking of. It took me over 12 hours of reading to understand this.
It would be helpfull for people to understand if you get more info into your video but begs the question, why has nobody else figured this out?
@MootNews Yes it takes a bit more reading if not knowledgeable in Digital/Radio/Data/Electronics & RFI-EMI.
If your not looking for what I I’m saying, everything will test/work fine.
I plan a 3rd Vid for Youtube, direct to point with more data.
Must be careful how much info I post. It allows those with bad intent to create havoc with fly-by-wire autos traveling.
I want RFI resistance standards for all.
I will do live tests (assumes finding a willing owner for test) when weather improves.
Since when have the wiring harnesses in the ECU fuel and other engine systems EVER been proven to act as radio signal receivers?? And if this were even possible, barring harness damage such as shorts, we would be seeing this occur in a myriad of engine faults and failures across the spectrum, not just Toyota. You really need to stop screening and editing the users’ comments to support your credibility.
@kassandrasduplex Please read on Parasitic, Spurious & Harmonic radio signals & electromagnetic interference. Wikipedia is free
Happens all the time but referring only to automotive cases, it takes stronger signal because of all the metal outside of it. Or low power transmitter inside.
RF “strength” is relevant to power, distance and RF signal type
RF on/in a sensor, gives computer a incorrect reading and computer will respond improper but correct for the input
This is not limited to Toyota
As a ham radio guy, I understand this.
I’ve seen many car problems from rfi but none of the problems were dangerous like transmissions that shift to neutral etc
I did not know that some new cars are near complete electronic actuated. steering, brakes & gasfeed
If they are going to be all computer control, they need to address this issue of RFI / EMI standards
While I would never own a car built with computer actuation, I’m now scared that I may face one on road while using my equipment.
@OVINDEX Glad U know difference of Computer Assisted and Computer Actuated
Seen that neutral shift before. If you have model susceptible, keep your HFamps off especially when near metal structures (antenna match) I’m HAM also, studied in ’77. Tests not the same now. More detail then in tests about this kind of stuff but no transistor & digital stuff.
Yes, Scaring me is Computer Actuated Power Steering Assist. Imagine RF on pick-up sensor in steering column and how hard to steer if you can
