Well, I was giving the K2/100 heck (100 watts) on 40 meters tonight into a nice load (1.2) and things start stinking a little when I turn it back over to the other station. I had been sending code at around 18 wpm for about 10 minutes. I am running a Astron switching power supply. Then the rig shut off and did not come on again. The heat sink was not all that hot, but I noticed the large gauge wire and the fuse holder was warmer than what I would expect. The 20 amp fuse was not blown. I pulled the Anderson Power pole plugs....and the RED side of the plug is melted while the black plug is not. The RED Anderson Power Pole connector on the K2 is also slighly deformed from melting. I took the K2 over to another supply on the bench and the K2 came up. Looking at the schmatic....I must have drawn to much current for the connectors. Hardly seems to be plausible. What do you experts think here? Lee - K0WA
In our day and age it seems that Common Sense is in short supply. If you don't have any Common Sense - get some and use it. If you can't find any common sense, ask for help from somebody who has some common sense. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
