CONTINUOUS TONE CODED SQUELCH SYSTEM (CTCSS)

1

CTCSS uses a subaudible tone to control the squelch of transceivers, and by this system you can reject signals from undesired stations. Suppose that only stations "A", "B", and "C" are programmed with the same tone frequency. The squelch in “A” opens only when called by “B” or “C”.

USING CTCSS

1Select the desired band.

2Repeatedly press [TONE] until "CT" appears.

•Each time you press [TONE], the selection changes as shown below.

3Select the desired CTCSS frequency.

•To select this, refer to "Selecting a Tone Frequency" {page 25} and follow steps 2 to 4.

4When you are called:

The squelch of your transceiver opens only when the selected tone is received.

When you make a call: Press and hold Mic [PTT].

Note:

◆You can select a separate tone frequency for the CTCSS and Tone functions.

◆When using DTSS or Page with CTCSS, the squelch opens only if the correct tone is received and the received DTSS code or Page code matches the code stored in your transceiver.

◆If you select a high tone frequency, receiving audio or noise that contains the same frequency portions may cause CTCSS to function incorrectly. To prevent noise from causing this problem, select an appropriate noise squelch level using the SQL control.

■ Automatic Tone Frequency ID

This function automatically identifies the incoming tone frequency on a received signal.

1 Press [TONE] (1 s) to activate the function.

•A tone frequency display replaces the frequency display and the 1 Hz decimal begins blinking.

• When a signal is received, the transceiver begins scanning through all tone frequencies in order to identify the incoming tone frequency. When the frequency is identified, a beep sounds, and the identified frequency appears and blinks. The identified frequency is programmed in place of the currently set CTCSS frequency.

2Press any key to cancel the function.

TM-V7A specifications

The Kenwood TM-V7A is a sophisticated dual-band transceiver that has garnered the attention of amateur radio enthusiasts worldwide. Designed for VHF and UHF operations, it offers a plethora of features that enhance communication capabilities and provide a robust user experience.

One of the standout characteristics of the TM-V7A is its dual-vfo (variable frequency oscillator) configuration, which allows users to monitor two frequencies simultaneously. This feature is particularly useful for coordinating communications across different bands or for listening to two channels at once. The large, bright LCD display provides clear visibility of the operating frequency, with the ability to monitor a wealth of information, including received signal strength and battery voltage.

The TM-V7A supports a wide range of operating modes, including FM, AM, and SSB, making it versatile enough for different communication needs. The device is compatible with CTCSS (Continuous Tone-Coded Squelch System) and DCS (Digital-Coded Squelch), which adds significant convenience for group communications by reducing unwanted noise and interference.

Another important feature is its built-in APRS (Automatic Packet Reporting System) functionality. This allows operators to transmit their position automatically and share information with other APRS users. The built-in GPS capability enhances this feature, providing accurate location tracking that can be particularly beneficial during emergency response situations or for outdoor events.

For enhanced audio quality, the TM-V7A is equipped with a high-performance audio filter and variable bandwidth control. This allows operators to tailor the audio output based on the conditions of the band and personal preferences, improving clarity and intelligibility during conversations.

The transceiver is also designed with user-friendly navigation. The intuitive menu system enables easy access to settings and configurations, allowing operators of all experience levels to operate the radio effectively. Customization options further enhance user experience, with programmable memories allowing operators to save frequently used frequencies and settings.

The Kenwood TM-V7A’s rugged build quality ensures durability, making it suitable for both home and field operations. Its compact design allows for easy installation in vehicles or portable setups, making it an excellent choice for both casual users and serious amateur radio operators. Overall, the Kenwood TM-V7A stands out as a feature-rich transceiver capable of meeting the diverse needs of the amateur radio community, combining advanced technology with practical functionality.
