Hi Kjeld, One thing I do here is run the input voltage at 14.5V. The K3 can accept up to 15V, and the 0.5V gives the power supply some margin for overshoot. This station is on solar power, so its "natural" voltage is 13.6V. I use an N8XJK battery booster to get the 14.5V to the K3. The batte

Dear all, I have a K3/100 and an Acom 2000A and I am wondering how to get the cleanest signal. The K3 is supplied with 13.8V. I see several options. Adjusting the K3 to 9W thinking that the KPA100 does not kick in could be one method. Another one could be adjusting the K3 to 14W thinking that the
