And imperfect assembly is a mistake easily made. For the first year or so that I owned the K3 I had the problem of intermittent DC, requiring fiddling with the APP connectors until getting them positioned just right, only to have intermittent connections again whenever the rig was moved. Then, having read an earlier suggestion like the one Don just made, though skeptical that I could possibly have assembled them incorrectly, I decided to give the blades an extra shove from behind. Click. No more problems since.
I demur from saying whether I use solder or crimp. One can ruin friendships very quickly by debating matters of religion or politics.

If you look at the end of an APP and can see the spring finger as well as the contact blade, it has not been properly assembled. Give the contact blade a push from the wire side until the contact blade locks over the spring finger. If it will not lock, there may be solder on the contact blade preventing it from being fully inserted - remove the contact blade and either cut off the solder with a sharp knife or replace the contact blade. 73, Don W3FPR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
