When on 80 meters, the longer I hold the tune button down the higher the SWR goes to the point the KPA500 folds back with warnings. I don't usually hold down the tune button longer than about 5-6 seconds.
I use a Manual Palstar BT1500A tuner which does a good job of tuning my EFHW wire antenna. So the initial tune is very good. I sometimes will hold down the Tune button on the K3s for maybe 5-6 seconds with the initial tune at 1-1 SWR. The KP500 first shows a 1-1 SWR. Then 1.2-1, 1.3-1 and so on. I stop when it reaches 1.5-1. I suppose that initially the transmitting wire sends out the signal and over time the current backs up. I have torroids in place to prevent RFI coming back down the antenna transmission line. I only use the system for CW. So when I send, the problem does not escalate to the point of a dangerous SWR. I wonder if this is a normal problem when holding the tuning button longer? And since I do not hold down the key for a long period of time it doesn't develop. Still, I am looking at solutions. And I am concerned.
