I have been trouble shooting a problem that arose in the shack.
The problem is that while in a qso my kat500 will start rising in SWR's.
I decided to check the system out by hooking a dummy load to the coax connector at the tower.
The K Line performs as expected. SWR are 1:1 and it sits there during key down never changing.
So I hooked up the antenna again and tried it. After the tune the SWR is 1:1. If I sit there with it keyed for a little bit, I start seeing the swr rise and it faults.
Something is breaking down.
I have a Ultimax End feed no tuner needed antenna. It is basically a 9:1 UN UN connected to a 133' of wire. The shielded end is on the UN UN is connected to a 8 foot cooper ground rod.
So my question is other than the 9:1 UN UN inside the little box breaking down because of heat, is there any other thing I should check? I wanted to check everything before calling UltiMax tomorrow.
I think I have ruled out coax, and station but running it in dummy load. I can run qrp all day long on the antenna with 5 watts, even at 100 the swr's do not start rising. But I only run my amp at about 400 watts max on power and it starts rising with that amount of power.
Any suggestions or opinions are welcomed.
