This discussion has got me confused. If a power supply fails, it is pretty easy to fault find. If you use the correct size cable for the length you require, then it WILL work. Discussions on APP and test points seem to me to be a little pedantic as apart from from a power supply failure I have not had voltage drop issues other than killing a large battery bank while exuberantly working a field day operation some years ago. I blame Eric for chatting to me too long on that occasion....😊 From memory the only other fault I have seen was a disconnected APP on the board. The owner told me had no idea how that came about. I re-soldered the connection and the K3 came back to life. Caveat emptor......i have always used a heavier DC power lead.

This would check the accuracy of the K3 volt-meter as well. I don't remember what it looks like in the vicinity of the APP's. The next best thing we have is the 12V jack, but I think that has two diodes in series to it. Dick, n0ce On 10/26/2015 12:05 PM, Rich wrote: > Thanks to all.
