You can change the AF/IF (IF=12 kHz) settings to output a
12 kHz IF signal. In that case, you can listen to the DRM
broadcast with the application software receiver that is
installed onto your PC.

When the SEND terminal controls an inductive load, such
as a relay, a counter-electromotive force can malfunction
or damage the transceiver. To prevent this, we recommend
adding a switching diode, such as an 1SS133, on the load
side of the circuit to absorb the counter-electromotive force.
When the diode is added, a delay in relay switching may
occur. Be sure to check its switching action before operating.
