Our most popular Audio Surveillance Transmitter, but pushing 6mW instead of 20mW.
This difference will not negatively impact the performance of this transmitter, the range will only be subdued a minimal amount. If you require an audio surveillance transmitter that will be situated in a target location that is not abundant in obstacles, this is the transmitter for you. If you are expecting obstacles such as structures (man-made/natural) then the 20W V1TX is a better fit.
This is a permanent, always-on "hot-microphone", once the battery is inserted the VTX will begin live transmission of ambient and surrounding audio without interruption on the Ultra High-Frequency band.
The VTX will broadcast audio over a distance of 300 meters in a cluttered urban environment, up to 700 meters 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 VTX will arrive with its specific Tx/Rx frequency noted on its back.

In order to maintain its longevity, the VTX 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!
