Our Original Audio Surveillance Transmitter.

This is a permanent, always-on "hot-microphone", once the battery is inserted the V1TX will begin live transmission of ambient and surrounding audio without interruption on the Ultra High-Frequency band.

Measuring in at 32x28mm fully mounted, with a thickness of .8mm and weighing less than 12 grams, this tiny audio transmitter packs a powerful punch and pushes upwards of 14mW of RF power for up to 25-30 hours of continuous audio surveillance.

The V1TX will broadcast audio over a distance of 500 meters in a cluttered urban environment, up to 1 kilometer with LOS, through concrete, drywall, and thick bush to any UHF receiver. It operates on a single button cell battery.

Use this transmitter to remotely listen to an area of interest that requires discreet acoustic monitoring. We recommend any handheld UHF receiver capable of tuning into the 400MHz-434MHz range, this is a standard range in most UHF receivers. Our recommended handheld receiver is the BAOFENG UV-5R. Your V1TX will arrive with its specific Tx/Rx frequency noted on its back.

Crystal 00k/ASK Data Transmitter.


TINYTX's transmitters are easily paired with any compact hand-held transceiver. Any Two-Way UHF Radio will work, but we recommend the BaoFeng UV-5R from FengBros. Fengbros has been our trusted supplier for the last year, they offer certified Baofeng radios at the most competitive price.

In order to maintain its longevity, the V1TX comes potted with a compound that seals all onboard components. Only the microphone and the battery terminal are accessible and made visible.

Looking for something smaller and just as capable? The V3TX  is truly tiny, measuring only 13.9mm x 19.4mm x .8mm!
