As I have reported before, I am also having this issue, but in my case it is only in digital modes. I can run SSB without issue, low or high power, but if I try to do a digital mode it will eventually kick out. I am only running about 100-150 watts into an end-fed long wire, but it also will do it at times into a dummy load. Also using a data cable, latest firmware. nothing helps. Palstar has no answer either.
