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!
