And we all start running the legal limit on 2.3 Gig mobile, or they
drive by an EME station?<:-))
There have been problems with RF *from* cars (The early V6 in the Cab
Forward Chrysler products on 147.00 were particularly bad) and a number
of the manufacturers have a limit of 100 watts for transmitters in the
cars or the warranty will be void.
Probably the "new stuff" will be better than the older and particularly
the early computers in cars, BUT you never know what each will do until
it's out, or this could be a case like BPL where they figured the
density of hams was insufficient to cause *enough* problems to be a
problem for them.
This will be interesting as there is a LOT of 2.4 Gig stuff already out
there that has been designed to "boost the distance" (didn't say it was
legal) and I wonder what will happen with those and the cars using Wi-Fi
driving by? Of course if there is a ham antenna near by we'll probably
be the first target "of interest"
I'd not want to purchase a car that used Wi-Fi for any critical function
whether I wanted to run a ham rig in it or not.
As to the Prius, you can run 100 watts on HF *in* one or 50 watts out
on 144 and 440 . At least I have with no problems and that's a much more
intense RF field than 1500 watts from 70 feet. Actually I also have my
40 Meter sloping dipoles about that distance from where we park the cars
and have had no problems in over two years. I too am running an old
Alpha 76A as well as the new Tokyo Hy-Power HL1.5Kfx. BTW, just
remember when running a ham rig in a Prius they have a battery about big
enough to start a lawnmower<:-)) so don't forget and leave the rig on.
