Matt: Wow, a Honda Civic -- I think my Hi-Q antenna might tip over a Honda Civic :-)
My vehicle is a 3/4 ton pickup truck, Chevy Silverado HD2500 Crew Cab so I have a large metal ground available. Thanks for your comments on your experience so far though. I know that my truck battery and charging system is pretty good and robust so I am assuming that I should easily achieve full output on the KX3+KXPA100. You raise another question though. What kind of mobile antenna? Screwdriver? If a screwdriver antenna, what method do you employe for tuning the antenna itself. Currently with my Icom 706 I use the N2VZ Turbo Tuner product but a version specific to the Icom 706. 73, phil, K7PEH On Jan 12, 2014, at 10:26 AM, Matt Zilmer <[email protected]> wrote: > I've started testing the KX3/KXPA100 mobile configuration, but don't > have all the cabling in yet and it's not permanent.
