Carl, If you look closely at the 3 terminal regulator that is U2, you will see that what you read as "78 MOSCT" is actually "78 M05" which is a proper 5 volt regulator - use it at U2.
You should have a 28 pin DIP with a piece of paper on the top with the KDSP2 firmware level. Don't peel the paper off, just believe it is the ATMEGA8L which is to be installed in the socket at U1. 73, Don W3FPR On 9/7/2010 9:23 PM, Carl Jón Denbow wrote: > I'm in the process of assembling my KDSP2 kit.
