For those seeking extended operating times with a smaller transmitter.
This compact Audio Surveillance Transmitter will broadcast for 6 days and approximately 6 hours continuously when a CR123A Li-ion battery is inserted (~150Hrs).
We chose this battery primarily because it is offered in both alkaline as well as a rechargeable li-ion cell, it packs plenty of capacity and is very small. The CR123A battery is readily available and can be picked up from many hardware stores and pharmacies.
This battery has a nominal voltage between 3.2-3.7v and has between 1500mAh and 1550mAh (mili-amp-hours). Expect excellent range & audio pickup with this transmitter.
This is a permanent, always-on "hot-microphone", once the battery is inserted, this device will begin live transmission of ambient and surrounding audio without interruption on the Ultra High-Frequency band.
The L2TX will broadcast audio over a distance of 700 metres in a cluttered urban environment, up to 1.2 kilometres with LOS, through concrete, drywall and thick bush to any UHF receiver, it operates on 1x CR123/A Li-ion cell.
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 transmitter 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.
