That is a good question, even though he is using a dummy load, a high SWR reading on an internal SWR meter could indicate a failure in the band pass filter stack. I've experienced this on my Yaesu FT-1000D, it was fine on the lower bands, but on 10 through 20, I had low power output and a high SWR reading on the internal SWR meter. My fault was I kept transmitting on the higher bands trying to diagnose the issue. It cost me a few capacitors, a new set of finals, and $125.00 in shipping.

Later, I discovered that my neighbor across the street had a lighting strike while I was out of town for the day. Oh well we live and learn, I did. Now I never keep my rigs hooked up when I am out of the shack. All coax, ladder lines and grounds go into a glass jar, and everything gets unplugged from the AC mains.

[QUOTE="295, post: 146986, member: 9162"] That is a good question, even though he is using a dummy load, a high SWR reading on an internal SWR meter could indicate a failure in the band pass filter stack.
