OPERATING THROUGH REPEATERS Repeaters, which are often installed and maintained by radio clubs, are usually located on mountain tops or other elevated locations. Generally they 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 communications without using repeaters. Most repeaters use a receive and transmit frequency pair with a standard or non-standard offset (odd-split).
5 OPERATING THROUGH REPEATERS ■ Activating Tone Function AUTOMATIC REPEATER OFFSET Press [TONE] to switch the Tone function ON (or OFF). • “ ” appears when the Tone function is ON. This function automatically selects an offset direction, according to the frequency that you select on the 2 m and 1.25 m (TH-F6A only) bands. The transceiver is programmed for offset direction as shown below. To obtain an up-to-date band plan for repeater offset direction, contact your national Amateur Radio association.
5 OPERATING THROUGH REPEATERS TONE FREQ. ID SCAN The reverse function exchanges a separate receive and transmit 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. This function scans through all tone frequencies to identify the incoming tone frequency on a received signal.
MEMORY CHANNELS In memory channels, you can store frequencies and related data that you often use. Then you need not reprogram those data every time. You can quickly recall a programmed channel through simple operation. A total of 400 memory channels are available for storing the frequencies, modes and other operating conditions of the A and B-bands. SIMPLEX & REPEATER OR ODD-SPLIT MEMORY CHANNEL? You can use each memory channel as a simplex & repeater channel or an odd-split channel.
6 MEMORY CHANNELS RECALLING A MEMORY CHANNEL CLEARING A MEMORY CHANNEL There are 2 ways of recalling the desired memory channel. To clear an individual memory channel: ■ Using the Tuning Control or / Keys 1 Press [MR] to enter Memory Recall mode. • The memory channel used last is recalled. 2 Turn the Tuning control or press [ ]/ [ ] to select your desired memory channel. • You cannot recall an empty memory channel. • To restore VFO mode, press [VFO].
6 MEMORY CHANNELS NAMING A MEMORY CHANNEL You can name memory channels using up to 8 alphanumeric characters. When you recall a named memory channel, its name appears on the display in place of the stored frequency. Names can be call signs, repeater names, cities, names of people, etc. 1 Press [MR] to recall your desired memory channel. 2 Press [F], [MN<->f] to enter memory name input mode. • The entry cursor appears.
6 MEMORY CHANNELS MEMORY CHANNEL GROUPS 400 memory channels have been divided into 8 groups of 50. Group 0 contains memory channel numbers 0 ~ 49, group 1 is 50 ~ 99, group 2 is 100 ~ 149, and so on. You can categorize each group to store similar data, same frequency bands or same modes for ease of use.

The transceiver displays the memory channel number in place of the operating frequencies. 2 Turn the Tuning control or press [ ]/ [ ] to select your desired memory channel number. While in the Channel Display mode, only the following keys can be operated.
SCAN Scan is a useful function for hands-off monitoring of your favorite frequencies. By becoming comfortable with all types of Scan, you will increase your operating efficiency. This transceiver provides the following types of scans.
7 SCAN PROGRAM SCAN You can limit the scanning frequency range. There are 10 memory channel pairs (L0/U0 ~ L9/U9) available for specifying the start and end frequencies. It monitors the range between the start and end frequencies that you have stored in memory channels L0/U0 to L9/U9. Before performing the Program Scan, store the Program Scan frequency range to one of the memory channel pairs L0/U0 ~ L9/U9. ■ Storing Program Scan Frequency Range 1 Press [VFO]. 2 Press [BAND] to select your desired band.
7 SCAN MEMORY SCAN Memory Scan monitors all memory channels in which you have stored frequencies (All-Channel Scan) or only a desired group of memory channels (Group Scan). ALL-CHANNEL SCAN The transceiver scans all of the memory channels in which you have stored frequencies. 1 Press [MR] (1 s). • Scan starts from the last memory channel number and ascends up through the channel numbers (default). Turn the Tuning control or press [ ]/ [ ] to change the scanning direction.
7 SCAN CALL SCAN PRIORITY SCAN A Call channel can be stored for each amateur radio band, such as the 2 m, 70 cm, and 1.25 m (TH-F6A only) bands {page 19}. You can monitor one of these Call channels and the current operating frequency alternatively. You may sometimes want to check your favorite frequency activities while monitoring the A and B-bands. In this case, use the Priority Scan function. It checks the activities of Pr1 and Pr2 channels every 3 seconds, alternately, using the B-band receiver.
7 SCAN Note: ◆ The signal being received on the B-band may become intermittent because the Priority Scan uses the B-band receiver to check the priority channel(s) activities. ◆ When a signal is received on a Priority channel with a CTCSS or DCS code programmed, the Priority channel is recalled even if a different selective tone/ code is detected. However, the transceiver only unmutes if the signal has the same CTCSS tone or DCS code.
7 SCAN USING VISUAL SCAN (MEMORY CHANNEL) 1 Press [MR] to enter Memory Recall mode. 2 Turn the Tuning control or press [ ]/ [ ] to select your desired center memory channel. 3 Press [F], [INFO] to start the Visual Scan. Note: ◆ The Program Scan memories (L0/U0 ~ L9/U9) and Priority channels (Pr1 and Pr2) cannot be locked out. ◆ Even if a memory channel is locked out, you can perform the Call Scan {page 25} between the Call channel and memory channel.
SELECTIVE CALL CTCSS and DCS CTCSS You may sometimes want to hear calls from only specific persons or groups. In this case, use the selective call function. 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. The transceiver unmutes only when it receives the signal having the same CTCSS tone or DCS code.
8 SELECTIVE CALL CTCSS FREQ. ID SCAN DCS This function scans through all CTCSS frequencies to identify the incoming CTCSS frequency on the received signal. You may find this useful when you cannot recall the CTCSS frequency that the other persons in your group are using. DCS is similar to CTCSS. However, instead of using an analog audio tone, it uses a continuous subaudible digital waveform that represents a 3-digit octal number.
8 SELECTIVE CALL DCS CODE ID SCAN This function scans through all DCS codes to identify the incoming DCS code on the received signal. You may find this useful when you cannot recall the DCS code that the other persons in your group are using. 1 While in DCS mode, press [F], [TONE] (1 s) to start the DCS Code ID Scan function. • • • To reverse the scan direction, turn the Tuning control or press [ ]/ [ ]. To quit the function, press [ ] or [PTT].
DTMF FUNCTIONS The keys on the keypad also function as DTMF keys; the 12 keys found on a touch-tone phone plus 4 additional keys (A, B, C, D). This transceiver also provides 10 dedicated DTMF memory channels. You can store a DTMF number (16 digits max.) with a memory name (8 digits max.) in each of the channels to recall later for speed dialing. Many repeaters in the U.S.A. and Canada offer a service called Autopatch. You can access the public telephone network via such a repeater by sending DTMF tones.
9 DTMF FUNCTIONS • • • Pressing [ ] after selecting the 8th digit completes the programming. To complete programming a name with less than 8 digits, press [MNU] or [ ] twice. Each press of [ ] causes the cursor to move backward. 9 Press the keys in sequence on the keypad to enter a DTMF number with up to 16 digits. ADJUSTING THE DTMF TONE TRANSMISSION SPEED This transceiver allows you to configure the DTMF number transmission speed between Fast (default) and Slow.
