The 9VTX is a 9V battery-operated Audio Surveillance Transmitter.
- Alkaline 9V will provide 50-55 hours of audio surveillance.
- No switches or indicator lights.
- This is a permanent, always-on "hot-microphone", once the battery is inserted the 9VTX will begin live transmission of ambient and surrounding audio without interruption on the Ultra High-Frequency band.
- The 9VTX will broadcast audio over a distance of 700-900 meters in a cluttered urban environment, up to 1 kilometer with LOS, through concrete, drywall, and thick bush to any UHF receiver, for better performance, use a Li-ion rechargeable 9V.
Use this transmitter to remotely listen to an area of interest that requires discrete 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 or the AnyTone AT-318UV. Your 9VTX 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 9VTX is potted with a compound or wrapped in a heat-shrink sleeve that seals all onboard components, only the microphone and the battery terminal are accessible and made visible.
