Hi Well my two KDSP2's arrived today. I built one of them. About 1.5 hours. The next one should be quicker. It is working fine in old #1808. Now I need to go back and do all the A to B mods on #1808 and install the 2.5KHz SSB bandwidth mod. At first try out the KDSP2 is very nice. I only did a quick check out with the default settings. Sounds good. Don Brown KD5NDB
