Ronnie, Two thoughts:
1. What is your power supply output voltage with the K3 transmitting. This measurement should be made at the K3. It should be approximately 13 volts. 2. Try transmitting into a 50 ohm dummy load vs. your antenna. Is there any difference? 3. Repeat 1 with the K3 connected to the dummy load. These measurements may help you identify if you have a problem with the K3, your antenna or your power supply + cabling from the power supply to the K3.
