KF6SDM license expired on 7/29/2008 so you are no longer able to talk on any ham radio until you retest. The grace period ended 7/30/2010. Ham radio licenses are good for 10 years and the need to be renewed at no cost. The only cost for a license is to take the exam, usually $15. If you want a vanity call there is a cost, I think it is about $25 now, again for a 10 year period. CW (Code) is no longer required for any license level, since I believe 2005. A Technician level license will let you talk on 2 meters, 440mhz/70cm, or higher UHF/VHF. Also the entire 6 meter band and 200mhz in the 10 meter band from 28.300 to 28.500 on SSB. CW can be used in a number of bands in the lower frequencies. I would advise you purchase a ARRL license manual for Technician and study it. You are in CA and there is a lot of amateur radio activity there so I suggest you find a local club and get some help from there. Just do a Google search. If you go to www.arrl.org
you will find a lot of information. You can also search for a local club there. Tons of other web sites for ham radio. By the way, the FCC no longer issues a paper license unless specifically requested but you can download a copy from the FCC web site.
