I have heard the 590 (like others) has a power overshoot problem, but I have read that version 1.07 from kenwood fixes that, and other places, a hardware remedy is needed and V1.07 won't fix the problem. Anyone have any real info on this? Is this particular to menu settings, serial number production runs, etc/?
I fail to see how this relates to the original post - might I suggest a new thread to manage your unrelated issues with this rig?
I have a TS-590S and have found that it has some good features when it comes to noise reduction on the low bands. I'd really like to let it stretch its legs in the wintertime, though, to get a better feel for its capabilities. But the earlier poster is correct - based on my observations, this unsung rig is absolutely outstanding at features that enhance its selectivity in crowded band conditions!
My primary prior rig had been the Kenwood TS-440S, now rather long in the tooth but still very effective at making contacts!
