List mates: The link below leads you to an article from Electronic Design magazine. It concerns RFI issues in electric drive vehicles (and, by extension, hybrids, as well). The primary focus is on th
Dale, Thanks for the link, it opened up fine for me. I was looking at a Toyota Prius today while at the Toyota dealer for oil change on my Sienna. Very impressive vehicle. 73 Dale, K9VUJ ____________
My son has a honda hybrid and it creates so much noise that HF operations are impossible. I have heard similar about other hybrids. Stay away if you plan to try to operate a hf rig in them. A recent
When I monitor HF while mobile in SSB with noise blankers and DSP turned on to entirely eliminate noise generated by my own vehicle, I hear the bloody Prius cars nearly a quarter mile away on a 5' w
I have a Prius and will be testing HF operations. I'll report the results here soon. 72 Ron, wb1hga _______________________________________________ RFI mailing list RFI@contesting.com http://lists.co
We have a Prius Hybrid: No RFI issues to either the entertainment center or the rig. Most of the Hybrids I've seen/driven had too small a battery and light gauge wiring to run much of a radio. The ba

This is rubbish. Measurements I have made at HF show an 8-10dB increase in signal every time the distance is halved for ground wave. Do the math! I have a neighbor with a 2010 Prius and I have follow
Roger, First, my thanks to you and the other responders to the post. The replies have certainly been interesting, as well as somewhat varied. I have a comment and a question for you. First, the comme
Well, whoopity-doo for you. In the meantime, I've heard them at great distances over several years and can tell when they are coming, even when I can't see them, for example on another road, behind
Let's do the math for all to see. Assuming a 9dB increase in signal for every halving in distance and using your number of 1800'. Then there would be a 9dB increase in interference @ 900', 18dB @ 450
I wrote the author and asked, but have not heard back, but that's only been about 7 hours. As I said in the previous post, we own an "older" Prius. It's unlikely we'll ever break even with the extra

My son's Honda like I said is 2004, I think, The noise on 20m with a Yaesu 857 and atas 120 is 20 over 9 when the car is on. We did not spend much time trying to figure out the issue. The batteries w

There was an excellent piece of analysis on NPR tonight noting that, with many of Detroit's newest gasoline models now in the 30-40 mpg range, many current owners say they would be unlikely to choose
Typically the small Hybrids are much more efficient in stop and go traffic, or very hilly terrain. and get their poorest mileage out on the highway at a high and steady speed. Taking US 10 from Midla
Certainly seems likely, since the gasoline engine can itself be a source of RFI (ignition, fuel injection). See the excellent website from K0BG: http://www.k0bg.com/ignition.html -- Charles M. Coldwe

I have a 2010 Prius and have had my Ft-857D in the Car for over a year and had no problem on the HF bands. I did have some RF at 6 Meters but very little and it did not stop me from using the band. A
You left out a couple of important factors. How strong the RFI is to begin with and how sensitive my equipment is, so despite all the math, it's worthless. Reasonable or not, this is what I have seen
