The modern Yaesu's and Icom's and early Flex radios have some of the dirtiest.
Bullshipper!!! I get excellent reports on my Yaesu's (new an old)....not many days go by someone stops and says...what are you running the audio is outstanding!
Those reports and numbers are like the Sherwood reports on receivers...
Don't mean squat , they have no TRUE bearing to what a rig sounds like "on the air"
It's all about matching one's voice characteristic's to the radio, what filters are added, and
how the operator run's said rig(s)...
Now in regards to the EASY operating TS-590!!!!...just a bells and whistle added 570...
The ergonomics of the 590 is no where close to the FTdx3000D....the Yaesu is much easier to operate and sounds better on both TX an RX.
The Kenwood(Panasonic)group of radios other than the $7000 TS-990 has seen no new innovations or serious improvements in the last 20 years...
Price wise the TS-480HX is their best equipment, in their radio line-up.
I ran Kenwood's for 20 years but when they basically sold out the Amateur division and stripped the R&D dept in lieu of business radio market.
The Amateur gear suffered almost until death.
But ultimately whatever you like...but until KWD dumps their present Amateur Plan and starts looking like they care about Amateur radio again...
I won't give them a second look.
And if you like all that fancy garbage on an outboard computer screen that's OK also..
I hear and work them first...the rest of you get in line
MHO
All the Best
