Our CTCSS encoder kit can encode up to 47 CTCSS tones with a sine wave output. The tone is selected by the combination of 5 jumpers in 6 positions.
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). The tone select inputs are constantly read so you could change tone with a switch. You can also tie the encode enable input to ground for continuous encode if you choose.
The CTCSS encoder kit gives a sine wave output as shown in this screen capture at 114.8Hz.
The full tone set is in the datasheet.
What’s in the box? A compact Gold Plated PCB, components and programmed PIC Microcontroller.
