Introducing the CTX3, our most compact transmitter to date and likely the smallest UHF Audio Surveillance Transmitter available worldwide. With dimensions of only 6.39mm x 18.56mm and a thickness of 0.8mm, the CTX3 sets a new standard in size efficiency. This transmitter is now available in a new SMD package crystal generating 20mW of RF power, ensuring superior frequency stability and delivering enhanced audio sensitivity.

The newest CTX3 provides over 30 hours of continuous audio surveillance, this model accepts standard alkaline CR2032 button cell batteries. Alternatively, the CTX3 is available as a standalone device with the (+) / (-) terminal pads tinned, allowing you to attach your own power or battery supply (ranging from 3V to 3.7V). This flexibility opens the door to virtually limitless operational time, enabling you to customize the power source to meet your specific needs. 

The CTX3 features a discreet design without switches or indicator lights, ensuring covert operation.

Once the battery is inserted, the CTX3 functions as a permanent, always-on "hot-microphone," immediately initiating live transmission of ambient and surrounding audio without interruption on the Ultra High-Frequency band. In a cluttered urban environment, the CTX3 broadcasts audio over a distance of 700 meters, extending up to 1.2 kilometers with Line-of-Sight (LOS) transmission. It effectively transmits audio through obstacles such as concrete, drywall, and dense vegetation.

Use the CTX3 for discreet acoustic monitoring of areas of interest. We recommend utilizing any handheld UHF receiver capable of tuning into the standard frequency range of 400MHz-434MHz, which is supported by most UHF receivers. For optimal performance, we suggest the Baofeng UV-5R or the AnyTone AT-318UV as our recommended handheld receivers. Additionally, you can also use any of our transmitters with SDRs (Software-Defined Radios). Your CTX3 will arrive with its specific Tx/Rx frequency clearly noted on its back, ensuring seamless compatibility with your receiver of choice.
