The surface mount IC for the KSB2 board is already pre-mounted. No need to wire it in place. The only thing that means is that one should handle the board itself in an anti-static environment. A wrist strap is good, but the addition of an anti-static mat is great. Connect the lead on the wrist strap and the mat to the AC safety ground - assuming you have proper house wiring. Make sure the AC ground is intact. You can obtain a simple tester for AC receptacles at a hardware or DIY store.
I agree the ATU is not packed as tightly, but for anyone who has completed the K2, either can be tackled without major problems - just follow the instructions (in order) and use good soldering techniques. 73, Don W3FPR On 1/1/2011 9:55 AM, John Ragle wrote: > The only possibly complicated spot in the ssb board is a tiny > surface-mount component, which is itself mounted on a small circuit > board that needs to be literally wired in place.
