[amsat-bb] RF noise from a passing-by BMW i3

[Zach Metzinger]

For those of you considering operating around electric vehicles, beware 
of the copious noise emitted by the BMW i3.

I was sitting in a parking lot, engine off, operating mobile on 10m 
during the recent band openings. Rather abruptly, the band's noise floor 
increased to mid-scale on the S-meter. I briefly wondered if propagation 
had suddenly changed, and then I noticed a BMW i3 pass behind me and 
leave the lot.

The noise left as well... I was back to a nice quiet band floor.

I didn't have time to switch over to 2m/70cm SSB and see how far up the 
racket extended.

I stumbled across an article relating much of the same, today.

So, save the planet or save the spectrum. Perhaps not both at the same 
time? :-)
