Telephone Conversations
by Tam

Continuing the theme of wiretapping of telephone conversations, mind you, in a previous article we discussed the first of our models of phone radiozhuchkov. Resembling only for stationary telephone we have three models 1) scutes, you can listen to telephone conversations MT01, which is connected to a telephone line in parallel and transmits acoustic information over the air MT01 2) Radio transmitter TR01 (we consider in this paper in more detail, but slightly later), allowing eavesdrop on conversations in the room where the telephone is installed, as well as their own telephone conversations 3) Telephone TU2 ear, whose job is eavesdropping room through phone's microphone (we touch on in more detail in another article) So, the phone radioretranslyator TR01 transmission range of acoustic signal is not large relative to worm and is only 150 meters to the line of sight, but keep in mind. That the emphasis in Scheme of radio transmission device is made and not at a distance. Bug TR01 is connected to a telephone line and is powered by it. His course as a transmitter MT01 can be integrated in the phone itself. Principle Work is not a big deal: the on-hook, the phone works like scutes TR01 wiretapping rooms, and when raised goes into podslushki calls. Signal transmission occurs by radio and made in the case of conventional radio receiver on a simple (FM frequency), and in case spetschastotnogo options – a special receiver, respectively (it is also possible we buy – not problemma). Microphone sensitivity lets you control rooms up to 50 square meters. As always, a little about the technical characteristics: Range (m) *: 150 Current consumption (mA): 5 Power supply (Volt): 9-60 Dimensions (Mm): 40X10H10 range: -10 C to +40 C Operating frequency (MHz): 96-98 Power: telephone line transmission frequencies can be adjusted more on our website
