For those in need of extended operating times. When paired with an 18650 Li-ion battery, this transmitter will broadcast continuously for an impressive 15 - 25 days, the 18650 battery, with a voltage of 3.7V and a capacity ranging from 2600mAh to 3500mAh, ensures extended power performance while maintaining excellent range and audio pickup capabilities. For upwards of 25 days of continuous operation, choose an 18650 with 3000mAh or higher. 

This transmitter is now available with a new extremely sensitive KNOWLES microphone, and a new high-powered crystal generating 20mW of RF power, ensuring superior frequency stability and delivering enhanced audio sensitivity. For custom power options to extend the operating time, please feel free to contact us for further assistance.

As a permanent, always-on "hot-microphone," this device initiates live transmission of ambient and surrounding audio immediately upon battery insertion, utilizing the Ultra High-Frequency band for uninterrupted signal transmission.

The L1TX excels in transmitting audio over a range of 700 meters in a cluttered urban environment, extending up to 1.2 kilometers with Line-of-Sight (LOS) transmission. It effortlessly transmits audio through obstacles such as concrete, drywall, and dense vegetation, ensuring reliable signal reception by any UHF receiver. The transmitter operates efficiently on a single 18650 Li-ion cell.

Use the L1TX for remote listening in areas requiring discreet acoustic monitoring. We recommend utilizing any handheld UHF receiver capable of tuning into the standard frequency range of 400MHz-700MHz, as this range is supported by most UHF receivers. Our recommended handheld receiver is the Baofeng UV-5R. Rest assured, your transmitter will arrive with its specific Tx/Rx frequency clearly indicated on its back.
