Newly thinking about an Amp I will have access to. Currently I use an end fed 80-10 with my ft-991A. Using my antenna analyzer the end fed has SWR ranging from 1.05 to ~1.6 (at 10) so I always use the internal tuner on HF and all seems to be just fine. Of course the tiny display on the 991A makes it difficult to see what the SWR ends up being after tuning. With the consideration of adding a gifted to me Ameritron AL800, I am wondering how to approach tuning. Do I still tune using the FT-991A at all? What range of SWR can the Ameritron tolerate? (don't see that in the manual), and do I need a tuner between the amp and coax, and does it need to be able to handle the max PEP the amp is theoretically able to output? I don't expect to be driving the amp to extremes on SSB. Do I really need a tuner rated to handle more than 500 watts? Lots of reading to do before turning the darn thing on I guess.
