## Overview

The Ramsey TT7 DTMF Touch Tone Decoder Kit is a high-quality electronic kit designed for decoding DTMF tones from various sources like telephones and radios. With a stable crystal control and a versatile 20mA output, it can drive relays, LEDs, and digital devices. This compact kit requires assembly, making it a perfect project for tech enthusiasts looking to enhance their skills.

## Description

You can strap the TT7 for detection of any single digit, including the secondary A, B, C, D digits. When the decoder detects the selected digit, it will provide a closure to ground for driving a relay, lamp, sounder, or other such load of up to 20 mA. A commercial central office quality decoder IC chip is used, making the TT7 extremely reliable, fast and sensitive. You may connect the TT7 directly across the speaker or detector output on any receiver, and in fact, we even detail how it may be connected directly to a telephone line. We designed the TT7 to be small enough (about 2 square inches) to fit in many radios for easy installation. If your needs are simply single function remote tone control, the TT7 is for you. (For multifunction remote control, use our TG2 Tone Grabber). Runs on 5VDC. Size: 1 1/2" x 7/8" x 2 1/4". Ramsey Mini-Kits are handy, easy-to-build, easy-to-use functional kits that can be used alone or as building blocks in larger, more complex designs. Mini-kits have been used in projects as simple as blinking name badges or as complex as Radio Astronomy Telescopes. Consider these capable little kits the next time you build.
