4Select a DTMF Memory Channel (0 to 9) using the MULTI/ CH control.
5Press [SUB] to enter the desired memory name. Use [+]/
6Press [M.IN] to store the name into memory.
7Select the desired DTMF tone using [+]/
8Repeat step 7 until you enter all the desired DTMF tones. You can enter a maximum of 16 DTMF tones for each DTMF Memory Channel.
9Press [M.IN] to store the data into memory.
■Transmitting DTMF Memory Channel Data
To send the DTMF Memory Channel data while you are transmitting:
1Press QUICK MEMO [MR] while you are transmitting.
2The DTMF Memory Channel number and the memory name appear on the main
3Turn the MULTI/ CH control to select the DTMF Memory Channel you want to transmit.
4Press QUICK MEMO [MR] to transmit the DTMF tones.
•The DTMF tones are monitored through the speaker while they are transmitted.
■DTMF Tone Time Length
When transmitting a series of DTMF tones, each tone duration is set to the 50 ms (tone)/ 50 ms (mute) format as default. Some repeaters or auto patch controllers may require longer DTMF tones and mutes.
1Press [MENU], then turn the MULTI/ CH control to access Menu No. 45B.
2Press
3Press [MENU] to exit the Menu mode.
The DTMF tones will now be sent using the 100 ms (tone)/ 100 ms (mute) format.
DTMF Pause Period
In the DTMF Memory, you can enter blanks (pauses) among a series of DTMF tones. The default pause period is set to 500 ms, but you can change this value by accessing Menu No. 45C.
1Press [MENU], then turn the MULTI/ CH control to access Menu No. 45C.
2Press [+]/
3Press [MENU] to exit the Menu mode.
HF RX ANTENNA
If you have a separate HF antenna (below 30 MHz) only for receiving, connect the antenna coaxial cable to the HF RX ANT connector on the rear panel. This connector is considered to be connected to a beverage antenna or directional loop antenna for low- band operation.
To use the HF RX ANTENNA connector, access Menu No. 18 and select ON. When the HF RX ANTENNA is selected for receiving, “” appears on the display.
LINEAR AMPLIFIER CONTROL
When you connect an external HF linear amplifier to the
Some linear amplifiers require a long transmission delay time because of the slow antenna relay switching time. In this case, select 2 for the slow switching.
If you have 50 MHz, 144 MHz, 430/ 440 MHz, or 1.2 GHz band linear amplifiers, connect the linear amplifier control cable to the EXT.CONT connector for these bands {page 96}.
1Press [MENU], then turn the MULTI/ CH control to select Menu No. 28A (HF), 28B (50 MHz), 28C (144 MHz), 28D (430 (440) MHz), or
28E (1.2 GHz).
