k2/100 and kat100 all working great on all bands at all power levels for
months. Then two days ago I could not get the kat100 to hold swr after tuning. It goes all over the place causing power supply,and the k2 to shut down along with hi-reflec and hi-current. This occurs only on 40 meters. There is no problem on any other band or frequency. Now comes the strange part. If I pull the kpa100 dc cord, I can run the qrp and kat100 at 15.2 watts on all bands all frequencies with no problems forever! But if I connect up the dc cable, the problem starts at 14 watts and the kat/k2 go crazy on 40 meters. I have tried 3 different power supplies in different locations 6 feet or more from rig. Changed or checked out all coax jumpers, Balun, ladder line, and antenna and ground. I can hook the k2 to my mfj-993 auto-tuner and there is no problem, it all tunes fine with the kpa100.. I can manually tune with no problems with the kap100 powered up as well. Is it possible to have a problem with just 40 meters on the kat100? H s anyone else ever experienced this? By the way, I have a ts-570 coax switched into this same antenna setup and no problems with the switches or coax or antenna or it's parts. Help!

Reggie,
Check the power cord and the Anderson Power Pole connector at the KPA100 end carefully. If the K2 is shutting down, it is quite likely that there is a bad connection somewhere in the power supply cord and components. 73, Don W3FPR ----- Original Message ----- From: "k6xr" <[hidden email]> To: <[hidden email]> Sent: Friday, December 24, 2004 7:47 PM Subject: [Elecraft] k2/100 problem-help > k2/100 and kat100 all working great on all bands at all power levels for > months.

A bad connection at one of the pressure contacts against the fuse, or a bad fuse with a partial break can show full voltage at the KPA100 until it tries to draw current.

If you are using a non-resonant antenna try lengthen (shortening) the
antenna lead in. Add a length of coax and see what happens. You could have an unloadable length of line. >> This occurs only on 40 meters. There is no problem on any other band or frequency.
