¥See ÒSelecting Subtone FrequencyÓ and ÒContinuous or Burst Subtones?Ó for more details on the Subtone.

To store data selected in Steps 1 ~ 8 in a memory channel:

9Press [M.IN].

10Turn the M.CH/VFO.CH control to select a channel (excluding channel 99).

11Press [M.IN].

To send a Subtone that is stored in memory:

12Press [RX M.CH].

13Turn the M.CH/VFO.CH control to select the channel.

14Press [PTT] or [SEND].

Note:

When operating through a repeater, over deviation caused by speaking too loudly into the microphone can cause your signal to Òtalk-offÓ (break up) through the repeater.

When Subtones can be transmitted, ÒTONEÓ lights on the Display.

Memory Transfer does not copy the stored Subtone frequency data to the VFO.

The Subtone transmitted is the tone associated with the memory channel or the VFO frequency that is used for the transmit function. When you transmit using a VFO frequency or the channel 99 frequency, the Subtone selected via Menu No. 57 (SUB.TONE) and Menu No. 58 (SUB.TONE) will be used; however, when transmitting using a memory channel, the Subtone stored in that channel will be transmitted.

Selecting Subtone Frequency

Some 10-meter FM repeaters use CTCSS (Continuous Tone Coded Squelch System) to prevent other repeaters on the same frequency from keying thus locking each other up. This repeater access system is also referred to as Tone or PL (ÒPrivate LineÓ). If CTCSS is used by a repeater in your area, set the Subtone frequency. The default is 88.5 Hz.

European Operation: In Europe, a 1750 Hz tone is generally used to access repeaters.

Select the Subtone frequency you require via Menu No. 57 (SUB.TONE). The available choices are shown in the table.

Continuous or Burst Subtones?

In addition to selecting the frequency of the Subtone, you must choose the correct Subtone duration. The Continuous selection sends the Subtone continuously as long as the transceiver is transmitting. The Burst selection sends a 500 ms Subtone burst each time the transceiver begins transmitting.

Select either Continuous or Burst via Menu No. 58 (SUB.TONE). The default is Continuous. This selection cannot be stored in a memory channel.
