5 COMMUNICATING AIDS Preamplifier The preamplifier can be configured to one of the two options: low gain type that places priority on IMD (PRE 1) and high gain type that places priority on sensitivity (PRE 2). Press F [ANT/PRE]. Pressing F [ANT/PRE] each time switches the selection in the following sequence: "PRE 1" → "PRE 2" → "OFF". • The preamplifier selection is stored for each antenna selection band. • The default values are as follows. Less than 7.5 MHz: OFF 7.5 MHz to less than 21.5 MHz: PRE 1 More than 21.5 MHz: PRE 2 RX Monitor If weak signals are received while the squelch is closed, the signals tend to be interrupted. Also, you may sometimes want to monitor the condition of the RX frequency while in the CTCSS standby state. In this case, the RX monitor is used to open the squelch temporarily. "RX Monitor" (Menu [0-15] to [0-31]) can be assigned to a PF key. While the PF key that is assigned with "RX Monitor" is pressed and held down, the squelch opens and the RX frequency can be monitored. The RX monitor turns OFF once the key is released. Scanning is paused while PF [RX Monitor] is pressed. SWL (BCL) Mode The SWL (BCL) mode is intended for SWL (Short Wave Listening) and BCL (Broadcast Listening) by displaying the horizontal dial of the "9R-59" communications receiver on the screen. 1 Press [MENU]. 2 Press F [SWL] to display the SWL screen. • If F [SWL] is not displayed, press F [MORE]. • Restrictions are applied to the following functions in the SWL mode. Function Transmission Sending of voice message Decoding/Encoding Sending of CW message TX output power limiter Meter switching TX filter switching Turning ON transverter FM tone Antenna tuning Configuration of the TX equalizer and related settings Disabled Disabled Disabled Disabled Disabled Disabled Disabled Disabled Disabled Disabled Disabled Status Band Switching in the SWL Mode (VFO Mode) Press F [BAND ]/ F [BAND ]. • The "broadcast/meter band" is displayed when the frequency falls within the band range. The preset broadcast bands are shown in the table below. Broadcast/ Lower Limit Upper Limit Meter Band [kHz] [kHz] LW 145 285 MW 525 1705 120 m 2300 2495 90 m 3200 3400 60 m 4750 5060 49 m 5900 6200 41 m 7200 7450 31 m 9400 9900 25 m 11600 12100 21 m 13570 13870 19 m 15100 15800 16 m 17480 17900 15 m 18900 19020 13 m 21450 21850 11 m 25670 26100 Default [kHz]/ Mode 145 525 2300 3200 4750 5900 7200 9400 AM 11600 13570 15100 17480 18900 21450 25670 • The band segments of the SWL mode that is preconfigured on this transceiver are represented in a slightly different way compared to conventional meter bands. Different band segments are used so as to achieve wider coverage to include the broadcast bands of the different regions and other bands. 3 Press [MENU] followed by F [SWL]. Returns to the normal screen. ● Switching to the SWL mode is not possible while the transverter is ON. ● An indicator is not displayed if a memory channel that is not registered is being called up. . 5-6
