As a proud owner of the brand new Kenwood TS-590 of course I now have to follow the release of new firmware for this rig. This morning I noticed there is a new one out. It addresses at least one thing I noticed: an unstable USB-data connection when I switch between N1MM logger and Ham Radio Deluxe. Sometimes I have to turn the radio off and back on to get a connection with the other program. Other fixes according to Kenwood:

1. In [SSB-DATA] mode, Speech Processor might not be disabled internally.
2. At the end of TX tune mode, carrier output returns to normal mode level after a short delay.
3. When the TS-590S is turned ON, the USB port connection may be unstable.
4. When the built-in electronic keyer is set to Mode A, CW keying may not work properly.
5. TX rise time power spike activates some linear amplifiers’ input power protections.
(The firmware Ver.1.02 revises the ALC response characteristics to reduce the power spike.)
6. When a separate RX ANT is connected, TX output power may be fed back to the RX ANT connector and might affect internal circuits.
(The firmware Ver.1.02 deactivates (opens) RX ANT relay every time the radio transmits.)

Let’s upgrade here!
