CITIZEN BAND-CRT ONE VOX
The CITIZEN BAND-CRT ONE VOX is a professional-grade Citizens Band (CB) radio transceiver designed for two-way voice communication over VHF frequencies in the 27 MHz band. This compact VOX-enabled unit is widely used by truckers, emergency responders, amateur radio enthusiasts, and field operations teams who require reliable hands-free communication capabilities. It solves the critical problem of maintaining constant communication channels during mobile operations while keeping both hands free for vehicle control or task execution.
Product Overview
The CITIZEN BAND-CRT ONE VOX operates on the standard CB radio frequency band (27 MHz) with integrated Voice Operated Transmission (VOX) technology that automatically activates transmission when sound is detected above a preset threshold. The unit features a compact desktop or mobile-mountable design with a microphone input jack, speaker output, and power supply connections. The VOX functionality eliminates the need for manual push-to-talk (PTT) button operation, making it ideal for situations where hands-free communication is essential for safety and operational efficiency.
This model incorporates a sensitive receiver circuit with automatic gain control (AGC) to maintain consistent audio levels across varying signal strengths, ensuring clear communication in both urban and remote coverage areas. The transmitter section delivers adequate RF power output within CB band regulations, with frequency stability maintained through crystal-controlled oscillation. The compact form factor and straightforward control interface make it suitable for installation in vehicles, mobile command centers, or fixed base stations where reliable CB communication is required.

- Amateur radio enthusiasts and CB hobbyists seeking reliable VOX-enabled transceivers for recreational and emergency preparedness communication networks
- Field operations, construction sites, and remote location coordination where mobile teams need reliable communication without infrastructure dependencies
- Security and surveillance teams requiring discreet hands-free communication capabilities during mobile patrols and monitoring operations
How to Use
Begin by connecting the CITIZEN BAND-CRT ONE VOX to a 12V DC power source using the appropriate power connector. If using automotive power, connect directly to the vehicle battery with proper fusing for safety. Mount the external antenna on the vehicle roof or structure for optimal signal propagation, ensuring the antenna is properly grounded. Connect an external speaker or use the built-in speaker by adjusting the volume control to a comfortable listening level.
To activate VOX operation, connect a microphone to the microphone input jack and adjust the VOX sensitivity control to your preferred threshold. Speak normally into the microphone and the unit will automatically transmit when sound exceeds the sensitivity setting. For manual operation, use the PTT button on the microphone if available. Select your desired CB channel using the frequency selector, ensuring compliance with local CB radio regulations. Test transmission and reception with another CB radio operator on the same frequency before deploying for critical operations. The VOX delay control adjusts how long the transmitter remains active after you stop speaking, preventing choppy audio cutoff.
Frequently Asked Questions
What is the difference between VOX and manual PTT operation on this CB radio?
VOX (Voice Operated Transmission) automatically activates the transmitter when it detects sound above a preset sensitivity threshold, eliminating the need to manually press a PTT button. Manual PTT requires you to hold down a button while speaking. VOX is ideal for hands-free operation in vehicles or situations where you need both hands free. The CITIZEN BAND-CRT ONE VOX supports both modes, allowing you to switch between them based on your operational needs.
What antenna should I use with the CITIZEN BAND-CRT ONE VOX for maximum range?
For optimal CB radio performance, use a quarter-wave vertical antenna (approximately 2.8 meters long) mounted on the vehicle roof or a high point. Magnetic mount antennas are convenient for temporary installations. Ensure the antenna is properly grounded to the vehicle chassis for efficient RF radiation. The transmission range typically extends 5-15 km depending on terrain, antenna height, and atmospheric conditions. Higher antenna placement and line-of-sight paths significantly improve communication distance.
Is the CITIZEN BAND-CRT ONE VOX legal to use in India?
CB radio operation in India requires proper licensing and authorization from the Wireless Planning and Coordination (WPC) wing of the Department of Telecommunications. While CB radios are available for purchase, their use is regulated. Verify current regulations with local authorities before operating this equipment. Some states permit CB radio use for specific applications like trucking or emergency services with appropriate permits. Always ensure compliance with local wireless communication laws before activating transmission.
Can I use this CB radio with a mobile phone hands-free system?
The CITIZEN BAND-CRT ONE VOX operates independently on the 27 MHz CB frequency band and does not integrate with mobile phone systems. However, you can use both simultaneously in a vehicle if desired. The CB radio provides a separate communication channel for CB network communication, while your mobile phone handles cellular calls. The VOX feature on the CB radio ensures it operates hands-free without interfering with phone operations.
