I'm looking at getting a used FT-991. Is there a serial number range to avoid? I've read all the horror stories of failed finals and SWR issues.
Have these issues been corrected in the 2016 model run? Not including the 991A of course.
To my knowledge, those issues ALL had to do with one single engineering change in 2013; They had to improve/add an additional ground strap on the final PA sub-assembly. Issue solved. I am unaware of anyone (knowledgeable/cluefull/following instructions) that has had any trouble or reliability issue with the 991 in 2015 and 2016 manufacturing runs. It is a great little radio. One of my friends beats the crap out of a 991 in portable ops with wire tossed over trees, pushing high watts in digital modes for hours on end. Zero issues there too.
Try one, you will like it.
And, you don't need to pay $500 extra for the "A" model that simply comes with
a second IF board for realtime scope display. I don't think that alone is worth
half-way toward doubling the cost of a great little radio. But a regular 991 model
and enjoy it.
