Programmable crystal controlled CTCSS (Sub Audio) Tone Encoder with 47 tones.

This Encoder can encode the 47 x CTCSS tones listed below and generates a sine wave. The tone is selected by the combination of jumpers in 6 positions, and the module is only 30 x 49mm in size. It's powered by 7 to 16V DC and draws only a few mA.

There is an encode enable input that connects to the radio's PTT line (active low), and the tone select inputs are constantly read so you could change tone with a switch if desired. You can tie the encode enable input to ground for continuous encode.

This item is supplied fully built and tested
