Hsb133 Receiver -

: Supports DVB-S/DVB-S2, H.265 (HEVC) decoding, and Multistream signals. Physical Ports

Serial monitor shows random 0 s and 1 s even when no transmitter is active. Causes: Weak power supply, no antenna, or excessive RF noise. Solutions: hsb133 receiver

| Parameter | Specification | |------------------------|------------------------------------------------------| | Frequency Range | 10 kHz – 1.6 GHz (continuous) | | Receiver Type | Direct Sampling SDR (14-bit ADC) | | Maximum Bandwidth | Up to 10 MHz (real-time) | | Tuning Steps | 1 Hz minimum | | Modes | AM, NFM, WFM, LSB, USB, CW, DRM (with software) | | Sensitivity (typical) | -130 dBm (HF, SSB) / -120 dBm (VHF, FM) | | Dynamic Range | > 100 dB (with preamp off) | | Image Rejection | > 70 dB (due to direct sampling) | | Selectivity | Software-defined (0.5 Hz to 500 kHz) | | Antenna Inputs | SMA (50Ω) + Hi-Z (500Ω) for longwire/loop (on some models) | | Front-end Protection | TVS diodes, optional high-pass filter for broadcast FM | | Power | USB 5V (≤ 500 mA) | | Dimensions | ~ 100 x 60 x 25 mm (pocket-sized) | | Weight | ~ 150 g | | Interface | USB 2.0 (Type B Mini or USB-C depending on revision) | Follow this standardized protocol to pair your hardware

While the VirtualWire library is obsolete, many legacy projects still use it. For modern projects, use the RadioHead library (ASK driver).

Setting up your receiver correctly prevents immediate signal drops and system failures. Follow this standardized protocol to pair your hardware safely:

: Watch for the flashing LED on the HSB133 to transition into a solid, unbroken color light. Remove the bind plug immediately to save your settings to the non-volatile memory bank.
