На сайте Kenwood размещена свежая прошивка v1.02 для трансивера TS-590S. О сути изменений, которые производит замена прошивки сказано следующее: 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.)
