LakeShark, developed by [SAMS0N1TE], is a compact radio scanner based on LilyGO T-Display P4. The device features an ESP32-P4, a 4.1-inch AMOLED touchscreen, an SX1262 LoRa module, GPS, and a nine-axis inertial measurement unit. Its software-defined radio capabilities can be expanded with an RTL-SDR Blog V3 or V4.
- It can scan P25 Phase 1 trunking broadcasts.
- It can monitor ADS-B signals.
- It can scan POCSAG broadcasts.
- It can receive FM radio broadcasts.
- It can display aircraft tracks on a minimap.
- It can examine bands using waterfall displays.
- It can investigate the activity of nearby nRF24 devices.
Why it matters
LakeShark expands the range of use for users monitoring radio signals by bringing different types of radio and broadcast signals together in a single portable interface. In addition to broadcasts such as P25, POCSAG, and FM, ADS-B tracking, displaying aircraft tracks on a map, and waterfall displays take the device beyond a receiver used solely for listening to audio. GPS and the inertial measurement unit enable features that use location and movement information to be used on the same device. However, the news text does not explain which additional bands and functions support for an RTL-SDR Blog V3 or V4 would unlock in practice, or the limits of these features under real-world usage conditions.
