Hi Tom, You might want to take a look at the KX3 Mobile User Guide, posted on Elecraft's web site: http://www.elecraft.com/K2_Manual_Download_Page.htm#kx3_mobile
I'm also a MARS op, and have used the KX3 mobile for MARS ops. The only issue I've found is making sure that the antenna is resonant. Standard-cut ham band resonators need mods sometimes, but if you're working with one of the screwdriver types of mobile antennas this is not a problem. With the shorter length antennas (Hustler in my case), the 100W amp is borderline mandatory, though I have worked a number of nets and events from the mobile without the amp: SSB, MT63, Thor, etc. Note also that I'm updating the Mobile User Guide. There will be some major structural and content refinements on the next go-around. Since I've decided to redo my mobile, I'll be document that development as it moves along. If you're interested, I accept docs for inclusion in the mobile guide and give credits. So far no one's taken me up on this. :) 73, matt W6NIA / NNN0UET On Sun, 14 Apr 2013 14:10:09 -0500, you wrote: >Hello all, > >I'm thinking about purchasing a KX3 for mobile use, and will >eventually want to use it for MARS mobile use with the 100W amp from >Elecraft. > >I'd like to see some comments from those who are using the KX3 as a >mobile. > >Thanks, > >73, >Tom >Amateur Radio Operator N5GE >ARRL Lifetime Member >QCWA Lifetime Member >73, >Tom >Amateur Radio Operator N5GE >ARRL Lifetime Member >QCWA Lifetime Member > >______________________________________________________________ >Elecraft mailing list >Home: http://mailman.qth.net/mailman/listinfo/elecraft >Help: http://mailman.qth.net/mmfaq.htm >Post: mailto:Elecraft@mailman.qth.net > >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:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
