Frequency Coverage
The SDS100 covers a wide range of frequencies, suitable for monitoring various services:
- 25-512 MHz
- 758-824 MHz
- 849-869 MHz
- 894-960 MHz
- 1240-1300 MHz
- Note: Cellular frequencies (824-849 MHz and 869-894 MHz) are blocked in the USA due to regulatory restrictions.
Modes Covered
The scanner supports both analog and digital modes, with some digital modes requiring optional paid upgrades:
- Analog Modes: AM, FM, NFM (Narrow FM), WFM (Wide FM), FMB (FM Broadcast)
- Digital Modes:
- APCO P25 Phase I and Phase II (standard)
- X2-TDMA (standard)
- Motorola, EDACS, and LTR trunked systems (standard)
- DMR (requires paid upgrade)
- NXDN 4800 and 9600 (requires paid upgrade)
- EDACS ProVoice (requires paid upgrade)
- Frequency Steps: 5, 6.25, 7.5, 8.33, 10, 12.5, 15, 20, 25, 50, or 100 kHz (user-definable or based on band plan)
Additional Notes
- Performance: The True I/Q technology excels in decoding digital signals in simulcast and weak-signal environments, outperforming traditional scanners. It’s particularly praised for handling Linear Simulcast Modulation (LSM) systems.
- Upgrades: Firmware updates are available via the microSD card or USB, ensuring the scanner remains current with new features and database updates from RadioReference.
- Use Case: Ideal for monitoring public safety (police, fire, EMS), railroads, aviation, marine, and amateur radio, though it cannot decrypt encrypted signals.
Even years after its 2018 debut, the SDS100 remains a top choice for scanner enthusiasts due to its versatility, durability, and cutting-edge technology.
