I run approx. 200 watts from my mobile. It's been trouble free over the last four or five years. To the best of my knowledge, no adverse effects on other vehicles either. I do use LMR-240uf throughout and employ numerous snap-on ferrites as well as a full toroidal RF choke between the output of the amp and the antenna. Also, all units are grounded directly to the vehicle chassis and bonded to each other. So far, so good.

What if you're running a KW, and gave a call on 20M. Suddenly, the guys brakes in the vehicle next to you locked up causing a multiple vehicle crash? I realize this is an extremely hypothetical and unlikely case, but these smart vehicle computer systems can't be all THAT immune to all sorts of RFI. I know the cruise control my 2000 Dakota would mysteriously jump 5 MPH if I keyed up with only 25 watts on 222MHz. It would return to it's previous setting when I un-keyed. VERY disconcerting eh? 73, Charlie k3ICH This begs the question: Why KX3s with KPA500s? That is what I use in my mobile station and it provides about 250W due to the FCC amplifier gain requirements. I am fine with it, as that is what I have and higher power may affect the vehicle. I have seen someone post a modification to remove an attenuator in the amp and recalibrate the power meter, but I would assume that Elecraft will not be allowed to do that, as the FCC Cert holder. 73, Mark W7MLG ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
