Hi Don, You don't need the KDVR3 for CW. The memory buttons work for CW without this option. You might want to consider the KXV3A if you plan to use a separate receive antenna or if you plan to add a P3 someday.
I have 400Hz and 200Hz filters. For CW I usually have my bandwidth set at 200Hz or lower. I use my 400Hz filter for RTTY where my bandwidth is usually 350Hz or 400Hz. You may want to consider just the 200Hz or 250Hz filter and buy another filter later if your operating style warrants it. The same argument can be used for buying only the 400Hz or 500Hz filter for CW and getting a narrower filter later. If money is not an issue buy both. I also have the 1000Hz filter and never find myself operating with a bandwidth in the 400Hz to 1000Hz range. One day I'll pull it out and sell it. Had I used my own advice I could have saved some money. 73, Mike K2MK Don KB1YBG wrote > > I'm about to place order for k3 kit.
