16 OTHER FUNCTIONS Linear Amplifier Menu Screen 1 Press [MENU]. 2 Press F [LINEAR AMP] to display the Linear Amplifier menu screen. • If F [LINEAR AMP] is not displayed, press F [MORE] to display F [LINEAR AMP]. Turning ON/OFF Linear Amplifier TX Delay Delay the switching operation by the transmission system of this transceiver when there is a long time lag before transmission starts on the linear amplifier in use. Configure "TX Delay" in Linear Amplifier Menu Setting Value Off (default)/ On ● When the TX delay of the linear amplifier is ON, TX delay time is added to the time from when transmission is started until the radio wave is output (usually about 15 ms). . 3 Press F6 [BAND] to switch to the target band. Pressing F6 [BAND] each time toggles the selection to "HF Band", "50 MHz Band" and "70 MHz Band" (E type only) in sequence. 4 Press F2 [ ]/ F3 [ ] to select the setting item. 5 Press F4 [-]/ F5 [+] or turn the [MULTI/CH] control to select the setting value. • The following settings are recommended when using the TL-922 (discontinued). Settings Menu Linear Amplifier Keying Logic TX Delay TX Delay Time (CW/FSK/PSK) TX Delay Time (SSB/FM/AM) Internal Relay Control External ALC Voltage TL-922 On Active Low On 15 35 On -6 [V] 6 Press [MENU] or [ESC] to end the process. • Pressing F [MENU TOP] returns the display to the menu top screen. Turning ON/OFF Linear Amplifier Switch the linear amplifier function for each target band to ON or OFF. Configure "Linear Amplifier" in Linear Amplifier Menu Setting Value Off (default)/ On Linear Amplifier TX Control TX control of the linear amplifier without using relay control can be performed via the 7-pin LKY terminal of the REMOTE connector. This function is used for TX control when using a linear amplifier that supports full break-in. Configure "Keying Logic" in Linear Amplifier Menu Setting Value Active Low (default)/ Active High Linear Amplifier TX Delay Time The TX delay time when using a linear amplifier can be configured separately for the CW/FSK/PSK and SSB/FM/AM modes. CW/FSK/PSK Mode Configure "TX Delay Time (CW/FSK/PSK)" in Linear Amplifier Menu Setting Value 5/ 10/ 15 (default)/ 20/ 25/ 30/ 35/ 40 [ms] SSB/FM/AM Mode Configure "TX Delay Time (SSB/FM/AM)" in Linear Amplifier Menu Setting Value 5/ 10/ 15/ 20/ 25/ 30/ 35 (default)/ 40/ 45/ 50 [ms] Linear Amplifier Relay Control When using a linear amplifier that requires TX control via a mechanical relay, the built-in mechanical relay terminals of this transceiver (pin 4 MKE terminal, pin 5 BRK terminal, pin 2 COM terminal of the REMOTE connector) are used. Configure "Internal Relay Control" in Linear Amplifier Menu Setting Value Off (default)/ On On: Activates the following relay control. • The MKE terminal is connected to the COM terminal during transmission. • The BRK terminal is connected to the COM terminal when there is no transmission. Off: Relay control is not activated and the BRK terminal remains connected to the COM terminal at all times. When using a linear amplifier that does not require control via a mechanical relay, configure to "Off" to minimize the relay sound. External ALC Voltage of Linear Amplifier Adjust the response of the ALC terminal (pin 6) of the REMOTE connector on this transceiver according to the linear amplifier in use. Configure "External ALC Voltage" in Linear Amplifier Menu Setting Value -1/ -2/ -3/ -4 (default)/ -5/ -6/ -7/ -8/ -9/ -10/ -11/ -12 [V] • Under normal circumstances, make adjustments on the linear amplifier without changing the default setting. 16-14
