Kenwood TS-990S firmware v1.08

The following features are updated.

1. Revises the functions of the Band Scope in Fixed mode.

Adds "Auto Scroll function" when long pressing [CTR/FIX] (F3) to apply Center mode display frequency range to Fixed mode.

When the marker for the selected band becomes off-range, the scope area shifts automatically in order to display the marker near the center.("Auto Scroll" appears on the upper left side of the grid then.)

When long pressing [CTR/FIX] (F3) to apply Center mode display frequency range to Fixed mode, or pressing [MKR.CTR] in Fixed mod​e, the revised lower / upper limit frequencies do not overwrite the configurations in Menu No.8-05 ~ 8-32.

2. Enables the selection of "0"(Off) for "Main Display" and "Sub Display" in "Dimmer 4" settings.
3. Revises the behavior when AC power is switched on.

When selecting "Off" in Advanced Menu No.22 (Standby State Low Power Consumption), after AC power is switched on by pressing the main I/O power switch or switched on at the household AC outlet using the AC cable, after 40 seconds the front panel power switch LED blinks orange for a few seconds and quick start by the front panel power switch becomes available.

4. Enables output of the 475kHz band (472~479kHz) signal from the rear panel DRV (drive output) connector as well as the 135kHz band.
5. When frequency tracking is on, changing frequency band for the main band does not turn the frequency tracking off.
6. Enables changing the band, mode, memory channel, or split operation settings while the CW/Voice Message screen is displayed.

Please also update the Radio Control Program
