Semi Auto Tune doesn't always work with my ftdx-3000d. I notice that no tuning action occurs when I press enter on the keypad unless the red tuning light is on. It's will sometimes come on when changing frequencies, and other times it will not.
Auto Tune does not do anything at all.
I have an FTDX-3000D connected to the ATU with a RS-232 straight through 9 pin cable. On my FTDX-3000D are; 037 CAT-RS232C, 038 CAT RATE - 38400bps (tried different rates), CAT TIME OUT TIMER (have tried various) - 1000ms, and CAT RTS - Disable (tried enable). On the ATU the settings are; Semi-Auto, CAT MODE, Baud Rate 38400bps.
I have a MIDI antenna (newly installed). My Version numbers are Board 1.06.0470 and Firmware V3.22 - which all looks like the latest.
Any help is appreciated.
