RAINBOWKITS TT-16 DTMF TONE DECODER KIT:
$42.95

As reviewed in QST Magazine July 2017, this DMTF decoder kit, when connected to a radio or scanner receiver output or phone line, provides a means to detect and control equipment by a DMTF tone issued from handheld radio or phone touch pad. Combine with the RELAY-5 kit, sold separately, to control up to 5 devices.
TONE DECODER Kit detects DTMF \"Dual Tone Multi-Frequency\" data (those sounds you hear when pushing buttons on your phone or radio keypad), and - when each button is pressed it sends a voltage to the electronics on the printed circuit board which turns a circuit on or off. Operates through phone lines, radios, or scanners. Connect to the output on a phone of receiver and use your cell phone or radio keypad to activate devices remotely or over-the-air. DPDT Relay on board capable of controlling upto 1.5Amp load.

There are 16 different touch tones, 12 of which are on a normal phone; special key pads have 4 additional buttons (A, B, C, D). This decoder gives an output voltage for all 16 touch tones. The Sweet 16 Tone Decoder has on the printed circuit board one (1) relay and driver circuit. If you want to use all 16 you can build your own board with 16 relays and driver circuits on it, or to get fancier use a flip-flop IC to achieve a \"toggle\" effect (push ON, push OFF), or a 555-timer to provide a timing effect (on for 5 minutes, then off) - the choices are almost unlimited. Any one output may be connected to the onboard relay circuit.Includes printed circuit board (PCB), components, and instructions.

Specifications:Supply range +7.5 to 18VDC.Relay output rating 125VAC up to 1.5A. PCB Size: 2.2\" x 2.8\"

Rainbowkits are intended for advanced-beginners and up. The builder must be able to identify common electrical components and their markings. Minimal skill at soldering is required. All parts are factory tested. Once soldering has begun the kit is not returnable.
