The KX3 allows you to add roofing filters (KXFL3 option), wherease kx2 does not.
“ The KXFL3 is actually 4 different filters that are shared between Phone and CW modes. Containing 2 filters for each mode, the filters switch points are: CW Mode: 500 hz and 1500 hz Phone mode: 1800 hz and your choice of 2400 or 2900, menu configurable” If the kx3 is your main radio, and your focus is CW, having the ability to add narrow passband filtering is essential. Are you planning to run more power than 10-15 watts? If so, adding capabilities up to 100 watts via an external amp is pretty simple. If you’re going to be adding more power, and don’t plan on using the portability of the kx3, consider a used K3/100 which has a lot more flexibility for narrow roofing filters, 100 amps built in and an easier path to adding a kw amp. 73, Lou, W0FK ----- St. Louis, MO "The difference between stupidity and genius is that genius has its limits."
