Hi Tom,

I installed 1.06 yesterday and the installation went without a hitch. 
According to the TS590 group, the update is supposed to help reduce 
interference on up conversion bands.

One thing that I noticed is that Kenwood has finally fixed the power button 
issue where if you hold the power button a little too long, the rig will 
turnoff and right back on.  Now after I installed 1.06, when I hold the 
button in to turn off the rig, it stays off!

Hi, all.

As you'll see below, version 1.06 of the TS590 firmware is now available
from Kenwood.

Has anyone successfully installed this update?

What are the advantages of doing so?

I currently have version 1.04 on my TS590, and am deciding whether or not to
take the leap and update my rig.

The process does involve some risk, so I just want to be careful here.
