Hi all, I'm bugeting for a K2 and need to know is it best to build the options during the initial build or is it OK to add them on later. Does one waste time in adding them on later? Finally, I operate 95% CW at 5 watts (now using the FT-817...BTW great rig.) What are the most important options to enhance the K2? tnx for the help.... 73 Jim Shaver KA7MQB Salem, OR
