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

I think over 100W you may have problems with HF and VHF. It can be a
problem.

One thing that works real well is to transmit near the x-ray radar band
where you have privileges. The traffic may slow down a bit as you set off
the radar detectors :-)

Where the heck do you get a 3cm transmitter, though? ha.

10.525 GHz is an amateur band, and is the same band used by the X-band
radars, and transmitters are readily available for $100. Gunnplexers
are one example, but people also use modified "microwave door openers"
to experiment in X band.
