This listing is for a full kit with SMD pre-soldered power cable and mounting screws.

All you have to solder are the switches/jacks/leds etc.

Although the pcb is smd pre soldered you will have to solder the large SMD led yourself as this is on the other side of the board and is purely a decorative feature.

IMPORTANT – Use a long cable for the output connection as the module uses this as the radio antenna.

Analog FM Radio with Automatic Channel-Search via Trigger/Gate

RADIO is an analog FM RADIO with an automatic channel-search functionality. It supports a frequency band of 83,5 – 114 MHz, has a built-in frequency control with signal quality evaluation and runs with automatic noise suppression.

By pressing the buttons CH- and CH+ you can activate the automatic channel-search function up or down the frequency range. If a signal passes the internal quality evaluation the search is ended and the radio signal is available at the OUT socket. If you want to change to another radio station channel-search is also accessible via CV. Simply patch any gate or trigger signal into the inputs CH- and CH +. Two LEDs indicate of a trigger or gate signal is applied. Channel changes can be really quick, if there are good signals close to each other on the frequency band. If the signal is bad the search automatism may need more time to find good signals leading to slower channel changes.

The RST button resets the search to the lowest frequency. After reset you will receive some really nice radio noises until you proceed to the next proper channel again. You can also route the CH- CV input to RST via jumper on the back of the PCB.

The module has two volume buttons for quick level adjustments. Additionally it has an active GAIN stage adjustable via trimmer in order to raise the maximum volume to modular levels. The patch-cable connected to the OUT socket acts as an antenna. It´s best to choose a long cable and move it around until you receive the best signals.

RADIO is a never ending sound source and a great companion for your Eurorack sampler or audio mangler.
