This transmitter was developed with wildlife researchers and Ecologists in mind who require discreet acoustic monitoring and data collection through a method that eliminates human presence and habitat disruption. 2x Rechargeable AA Lithium batteries are provided along with a charger.

This is one of our most popular Audio Surveillance Transmitters, pushing 18mW of RF and capable of transmitting ambient audio for 10 days straight. This is a permanent, always-on "hot-microphone", once the included rechargeable batteries are inserted the WTX5 will begin live transmission of ambient and surrounding audio without interruption on the Ultra High-Frequency band over a distance of 700 to 1000 metres through thick bush and vegetation, to any UHF receiver system (portable or stationary, including Software-Defined Radio receivers).

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-700MHz range, this is a standard range in most UHF receivers. Our recommended handheld receiver is a Baofeng UV-5R. Your WTX5 will arrive with its specific Tx/Rx frequency noted on its back.

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 WTX5 comes potted with a compound that seals all onboard components. Pictured housing will soon be offered in Anodized Aluminum. Only the microphone and the battery terminal are accessible and made visible. If you’re looking for even more operational time (12 Days), check out the WTX2 here.
