What it is

The RTL-SDR is a very inexpensive software-defined radio ( SDR) receiver: a small USB adapter, similar to a flash drive, connected to an antenna. Plugged into a computer, it works as a radio able to tune frequencies between about 500 kHz and 1.75 GHz, depending on the model. Unlike the HackRF, it only receives signals and does not transmit.

In TECER

It was part of the SDR kit as a bench receiver, alongside the TinySA and the HackRF, to observe the signals present in the bands of interest (see Phase 1 (BOLT): the project and the setting).
