Our flagship model. The V1TX is designed for unparalleled performance, this transmitter operates as a permanent, always-on "hot-microphone," initiating live transmission of ambient and surrounding audio immediately upon battery insertion. It seamlessly operates on the Ultra High-Frequency band, ensuring uninterrupted transmission. V1TX 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.

Measuring a mere 32x28mm when fully mounted, with a slender thickness of 0.8mm and weighing less than 12 grams, the V1TX may be compact, but it delivers exceptional capabilities. It generates a formidable RF power of over 20mW, enabling continuous audio surveillance for an impressive duration of 25-30 hours.

In challenging urban environments, the V1TX boasts a broadcasting range of 500 meters, extending up to 1 kilometer with Line-of-Sight (LOS) transmission. It effortlessly penetrates obstacles such as concrete, drywall, and dense foliage, ensuring reliable audio transmission to any UHF receiver.

Powered by a single button cell battery, this transmitter is the perfect choice 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. For optimal performance, we suggest the BAOFENG UV-5R as our recommended handheld receiver. Your V1TX will arrive with its designated Tx/Rx frequency clearly indicated on its back.
