7 COMMUNICATING AIDS CUSTOMIZING TRANSMISSION SIGNAL CHARACTERISTICS The quality of your transmission signal is important, regardless of which on-air activity you pursue. However, it is easy to be casual and overlook this fact since you don't listen to your own signal. The following sub-sections provide information that will help you tailor your transmission signal. ■ TX Filter Bandwidth (SSB/ AM) Use Menu No. 25 to select one of the following TX low-cut filters: 10, 100, 200, 300 (default), 400, or 500 Hz. Use Menu No. 26 to select one of the following TX high-cut filters: 2500, 2600, 2700 (default), 2800, 2900, or 3000 Hz. ■ TX Filter Bandwidth (LSB-DATA/ USB-DATA) Use Menu No. 27 to select one of the following TX low-cut filters: 10, 100, 200, 300 (default), 400, or 500 Hz. Use Menu No. 28 to select one of the following TX high-cut filters: 2500, 2600, 2700 (default), 2800, 2900, or 3000 Hz. ■ TX Equalizer (SSB/ AM/ FM) Use Menu No. 30 to change the transmission frequency characteristics of your signal. You can select from 1 of 6 different transmission profiles including the default flat response. Selecting any of the following items from the Menu causes " " to appear on the display. • Off (oFF): The flat frequency response for SSB, FM, and AM (default). • High boost 1 (Hb1)/ High boost 2 (Hb2): Emphasizes higher audio frequencies; effective for a bassi voice. High boost 2 does not reduce the low frequency as much as High boost 1. • Formant pass (FP): Improves clarity by suppressing audio frequencies outside the normal voice frequency range. • Bass boost 1 (bb1)/ Bass boost 2 (bb2): Emphasizes lower audio frequencies; effective for a voice with more high frequency components. Bass boost 2 emphasizes more low frequency response. • Conventional (c): Emphasizes by 3 dB frequencies at 600 Hz and higher. • User (U): Reserved for the optional ARCP software. Off (oFF) is programmed at the factory as a default. Frequency Response Curves Amplitude oFF Hb2 HP bb1 c 0.1 1.0 2.0 Audio frequency (kHz) Note: When using the ARCP-590, you can temporarily change each preset value. TRANSMIT INHIBIT Transmit Inhibit prevents the transceiver from being placed in transmission mode. No signal can be transmitted when this function is ON, even if Mic [PTT] is pressed. • TX Inhibit OFF: Transmission is allowed. • TX Inhibit ON: Transmission is not allowed. Switch this function ON or OFF via Menu No. 60. The default is OFF. BUSY LOCKOUT Busy Lockout prevents the transceiver from being placed in transmit mode if the current operating frequency is busy; in other words, if the squelch is open, you cannot transmit. • Busy Lockout OFF: Transmission is allowed. • Busy Lockout ON: Transmission is not allowed. Switch this function ON or OFF via Menu No. 74. The default is OFF. CHANGING FREQUENCY WHILE TRANSMITTING Moving your frequency while transmitting is usually an unwise practice due to the risk of interfering with other stations. However, if necessary, by using the Tuning control you can change the operating frequency while transmitting. You also can change the XIT offset frequency while in transmission mode. While transmitting, if you select a frequency outside the transmission frequency range, the transceiver is automatically forced to return to reception mode. 32
