  • Page 45: Operating Through Repeaters

    OPERATING THROUGH REPEATERS Repeaters, which are often installed and maintained by radio clubs, are usually located on mountain tops or other elevated locations. They generally operate at higher ERP (Effective Radiated Power) than a typical station. This combination of elevation and high ERP allows communications over much greater distances than communicating without using repeaters.

  • Page 46: Offset Programming Flow

    FFSET ROGRAMMING Select a receive frequency. Select an offset direction. Select an offset frequency (only when programming odd-split repeater frequencies). Activate the Tone function (if necessary). Select a tone frequency (if necessary). If you store all the above data in a memory channel, you will not need to reprogram the parameters every time.

  • Page 47: Selecting An Offset Frequency

  • Page 52: Reverse Function

    EVERSE UNCTION The Reverse function exchanges a separate reception and transmission frequency. So, while using a repeater, you can manually check the strength of a signal that you receive directly from the other station. If the station’s signal is strong, both stations should move to a simplex frequency and free up the repeater.

  • Page 55: Memory Channels

    MEMORY CHANNELS In memory channels, you can store frequencies and related data that you frequently use so that you do not need to reprogram that data every time. You can quickly recall a programmed channel through simple operation. A total of 100 memory channels (50 when using the Memory Name function) are available for storing frequencies, modes and other operating conditions.

  • Page 56: Simplex

    Note: If you change the memory channel capacity from 100 channels to 50 channels after having stored data in channels 50 to 99, all memory channel data in channels 50 to 99 will be erased. If you change the memory channel capacity from 50 channels to 100 channels after storing Memory names in those channels, all Memory name data will be erased.

  • Page 59: Storing Odd-split Repeater Frequencies

    Storing Odd-Split Repeater Frequencies Some repeaters use a pair of reception and transmission frequencies with a non-standard offset. If you store two separate frequencies in a memory channel, you can operate on those repeaters without programming the offset frequency and direction. 1 Store the desired reception frequency and related data by following the procedure given for simplex or standard repeater frequencies {page 44}.

  • Page 60: Recalling A Memory Channel

    You cannot recall an empty memory channel. • To restore VFO Mode, press [VFO]. Using a Numeric Keypad (TH-K2AT/ ET/ K4AT only) You can also recall a memory channel by entering a desired memory channel number with the keypad. 1 Press [MR] to enter Memory Recall Mode.

  • Page 61: Clearing A Memory Channel

    You cannot recall the Program Scan memory channels (L0/U0 ~ L2/U2), Priority Channel (Pr) and Weather Alert (AL) (TH-K2AT K/ K2 only) using the numeric keypad. When you recall an odd-split memory channel, “+” and “–” appear on the display. Press [F], [MENU] (Reverse function) {page 38} to display the transmission frequency.

  • Page 62: Naming A Memory Channel

    Note: Call Channel data cannot be cleared. You can also clear the Priority Channel, L0/U0 ~ L2/U2 and Weather Alert data. While the trasceiver is in Channel Display Mode or Lock function is activated, you cannot clear the channel data. To clear all memory channels contents at once, perform Full Reset {page 111}.

  • Page 67: Call Channel

    HANNEL The Call Channel can be recalled instantly no matter what frequency the transceiver is operating on. For instance, you may use the Call Channel as an emergency channel within your group. In this case, Call Scan {page 64} will be useful. The default Call Channel frequencies are 144.000 MHz for the 2 m band (all TH-K2 models), and 430.000 MHz (all TH-K4 models) for the 70 cm band.

  • Page 68: Reprogramming The Call Channel

    Reprogramming the Call Channel 1 Select your desired frequency and related data (Tone, CTCSS, DCS, or offset direction, etc.). • When you program the Call Channel as an odd-split channel, select a reception frequency first. 2 Press [F], [CALL]. • The selected frequency and related data are stored in the Call Channel.

  • Page 69: Weather Alert (th-k2at K/ K2 Only )

    EATHER LERT One of the NOAA Weather Radio channels can be programmed to the AL memory channel of the TH-K2AT. The transceiver can be configured to check the NOAA Weather Alert tone (1050 Hz) and will automatically alert you by recalling and monitoring the Weather Radio frequency when the Weather Alert tone is broadcasted.

  • Page 70: Enabling A Weather Alert

    Note: When you perform Full Reset {page 111}, the Weather Radio frequency recovers the factory default frequency (162.550 MHz). When you clear the Weather Radio channel {page 47}, the factory default frequency (162.550 MHz) will not be recovered. You can also transfer the AL memory channel data to the VFO or another memory channel.

Otherwise, it resumes scanning. Press and hold [MONI/SQL] to pause scan in order to monitor the scanning frequency.

  • Page 75: Program Scan

    3 Press [VFO] (1 s) to start Band Scan. 4 To stop Band Scan, press [VFO] or [PTT]. Note: While scanning, you can change the scan frequency direction by turning the Tuning control. The transceiver scans the frequency range that is stored in Menu No.

  • Page 82: Scan Resume Method

    ESUME ETHOD The transceiver stops scanning at the frequency (or memory channel) where a signal is detected. It then continues or stops scanning according to which Resume Mode you have selected. • Time-Operated Mode (default) The transceiver remains on a busy frequency (or memory channel) for approximately 5 seconds, then continues to scan even if the signal is still present.

  • Page 83: Selective Call

    CTCSS You may sometimes want to hear calls from only specific persons or groups. In this case, use the Selective Call. This transceiver is equipped with CTCSS (Continuous Tone Coded Squelch System) and DCS (Digital Coded Squelch). These Selective Calls allow you to ignore (not hear) unwanted calls from other persons who are using the same frequency.
