7 OPERATING AIDS

AUTOMATIC MODE

Automatic Mode automatically selects the operating mode according to a set of frequency and mode data that you input. The purpose of Automatic Mode is for the transceiver to select the correct mode for you as you tune within a band. For Automatic Mode to work, you must first program the frequency/mode relationships that you want.

AUTOMATIC MODE BOUNDARIES

•The defaults for all boundaries are 30 MHz USB.

•Boundaries may only be changed (not deleted).

•The mode assigned to a boundary will be selected while operating on all frequencies below that boundary down to and including the next lower boundary.

•Each boundary is numbered. As the boundary numbers get larger, so must the boundary frequencies.

Example: If Boundary No. 09 is 14.100 MHz, then Boundary No. 10 must be a frequency larger by at least 10 kHz than 14.100 MHz. The lowest frequency that could be stored in Boundary No. 10 is 14.110 MHz. A lower frequency will not be accepted.

•Frequencies larger than the maximum receive frequency cannot be stored.

•There is a maximum of 19 boundary frequencies.

•Automatic Mode is always “OFF” in the range from the highest boundary to the maximum transceiver frequency.

Example: If 18 MHz CW is stored in Boundary No. 14, tuning to 18 MHz or higher selects USB since the boundary default of 30 MHz USB is stored in Boundary No. 15. Whereas, if 18 MHz CW is stored in Boundary No. 18 (highest boundary), tuning to a frequency lower than 18 MHz selects CW but tuning to 18 MHz or higher will not change the mode (still CW).

Use the following procedure to change a boundary.

1Press [MENU]+[].

• Boundary No. 00 appears.

AUTOCW

2Turn the M.CH/VFO.CH control to select the boundary that you want to change.

AUTOCW

3Press [ENTER], then enter the frequency via the keypad. Alternatively, you can enter the frequencies by using the Tuning control or Mic [UP]/[DWN]. Pressing [UP] or [DOWN] on the Front Panel changes the frequency in 1 MHz steps.

• “– –.– – 0.00” appears if [ENTER] is pressed.

AUTOUSB

•The 10 kHz digit is the least significant that can be entered therefore boundaries must be multiples of 10 kHz.

•Four digits must be entered. However, if [ENTER] is pressed after beginning to enter digits, 0 is entered automatically for the remaining un-entered digits, and frequency entry is completed.

•If you enter a wrong digit, press

[CLEAR], [ENTER] then re-enter the entire frequency.

4Press [LSB/USB] or [CW/–R] or [FSK/–R] or [FM/AM] to select the mode for this boundary.

5Repeat Steps 2 ~ 4 for each boundary that you want to change.

6Press [CLR] to exit from this mode.

•Switching the power OFF before pressing [CLR] results in loss of the entered data.

USING AUTOMATIC MODE

Toggle Automatic Mode ON or OFF via Menu No. 34 (AUT.MODE). The default is OFF. When Automatic Mode is ON, you can always change the mode manually by pressing a Front Panel MODE button. An Automatic Mode boundary must be crossed for the mode to automatically change.

Automatic Mode does not work if you change bands by pressing [UP] or [DOWN]. Instead, the mode last used on the newly selected band will be recalled from the band memory. Switching ON the 1MHz Step function will allow Automatic Mode to work when using [UP] or [DOWN].

In SSB mode when Automatic Mode is OFF, the transceiver automatically selects LSB for frequencies lower than 9.5 MHz, and selects USB for 9.5 MHz or higher frequencies if the Tuning control or Mic [UP]/[DWN] is used to cross the frequency of 9.5 MHz. This is also true if using the Front Panel [UP] or [DOWN] button. In all modes, the RIT or XIT frequency shift is not taken into account by Automatic Mode. Also, Automatic Mode will not function if a frequency is entered via the keypad on the Front Panel.
