Default killing cars with high RF?

Just what the ham radio world needs, another cber who thinks it is
perfectly OK to operate at illegal power levels.


Who cares what you old school brass pounders think? I'll be an f'in
EXTRA on February 24th.

If if wasn't for CB'ers, there would be almost no influx of new hams.
Put that in your vibroplex and smoke it!

What's your call, CB?

hey, don't you know that all those "inbred cb operators" live in very
rural mountainous aras where they need the few hundred watts on 11
meters just for their signal to make it to their closest neighbor?

The legal 4 wats won't reach any of their neighbors in those areas.

So it's understandable why they run a few hundred watts.

Hi,
What's all this business I hear people talking about blasting people's
car stereos or killing cars altogether with high-power RF? I run 2m,
10m, and 11m in my jeep and I'd like to sort out the fact from the
legend and find out what kind of power I can use without risking
damage to my jeep or cars around me. At what power level is front-end
overload to a nearby radio likely? At what power level is damage
likely, and to what componets?

I am currently using only 50 watts on a 5/8 wave (2m), 25w on a 1/4
wave (10m), legal 4w on a 1/4 wave (11m)

Thanks,
Nelson KE5MBX


When I worked for Motorola AIEG (Automotive Group)... I did quite a
bit of testing of RF susceptability of engine controller modules that
Motorola made for Ford Motor Co. We used a giant stripline that was
powered by an RF sweep generator. We characterized disruptions caused
by RF fields under the stripline... while the engine controller was
running (simulation of real vehicle). Back then... it took about 200V/
meter of field strength... only at certain frequencies to cause major
module hiccups. Don't know how modern day modules fare against similar
fields. One thing I do know... in my current car repair manuals... it
warns against operating "high power" transmitters... warning that the
air bag may deploy. I guess that's how you know if you're really
gettin' out... when the air bag leaves the imprint of the microphone
on your face... lol

LMAO!

When you pull 90 amps in spurts like I did on sideband with a 667V,
it makes me wonder how I didn't pop my airbombs or kill my ECM!
But I was gettin' out!

Also, for a blank sun, DX was rolling pretty good. I made contact
with a guy 8000 feet up in New Mexico. Eight more days to the big
10 meter fest! Hear me there...

Let me relate this story, again, but I like it!

One time I pulled up to a red light while talking on my CB with a 667.
When I unkeyed, I noticed the guy next to me starting his car. When he
got it going, I keyed up and his engine died. I waited for the green
light and keyed up and nailed it! The guy was stuck at the light, restarting!

I used to be able to watch people's TV's flicker as I drove past, before cable.
Now I can turn on all the motion sensor lights on the street as I drive by
with a 2 pill.

One hour until there are no CW requirements anymore! Ye-ha! Got my Wilson 1000
mag mount, 2950, an external speaker and a cigarette lighter power cord ready.
I've got a few hour drive around town every day in a company car. I'll use my
KW-7 and 2 pill when I get back from my drive. I did a receive test Tuesday
night. The KW-7 has much better ears then a Wilson 1000 mag mount on 11 meters.
Of course, the antennas are tuned for 27 MHz. I'll have to cut a KW-7 down a
bit on the top to tune one for 10. Then I'll need to carry 2 of them, one for
10 and one for 11...tune for midway and be half-assed on both? Hmmmm.
