HTOOL SDR V4 Software Defined Radio Receiver RTL SDR V4 RTL2832U 1PPM TCXO HF BiasT SMA Software Defined Radio + Antenna

This is an RTL-SDR software-defined radio receiver with a RTL2832U ADC chip R860 (R820T2) tuner 1PPM TCXO SMA F connector and an aluminum housing with passive cooling. The tuning frequency range is 500 kHz to 1.7 GHz with an instantaneous bandwidth of up to 3.2 MHz (2.4 MHz maximum stable bandwidth or 3.2 MHz if your application can withstand USB drops). (HF works in direct sampling mode – V.3 and higher models only). Ideal for use as a computer-based radio scanner for use with freeware such as SDR# HDSDR SDR-Radio Linrad GQRX or SDR Touch on Android. Available for Windows MacOS Linux Android and even embedded Linux computers like the Raspberry Pi.

RTLSDR is suitable for many applications including general radio scanning air traffic control public safety radio ADSB AIS ACARS VDL2 trunked radio P25/DMR digital voice TETRAPOCSAG weather balloon APRS NOAAAPT or METEORM2 meteorological satellites 0uteet inmarsatlridium GSM Milsatcom radio astronomy Meteorological scattering monitoring. DAB or as a low-cost omnidirectional adapter for traditional amateur radios.

This RTLSDR unit has several improvements over the regular brand and others including:

–R860 (R820T2) tuner

–Improved tolerances for passive components

–One 1 PPM temperature compensated oscillator (TCXO)

–HF mode via built-in direct sampling (can be tuned up to 500 kHz while basic RTL-SDR can only be tuned up to 24 MHz)

–SMA F connector

–Aluminum shielded enclosure with thermal pads for passive cooling to improve L-band performance

–Software-activatorable 4.5V bias T-circuit

–Improved PCB design to reduce noise and spurs

–USB noise chokes more bypass capacitors and built-in ferrite to reduce PC noise

–Improved ESD protection (additional ESD diodes and additional ESD discharge paths)

–Improved front-end circuitry designed for wideband use (other models still use circuits designed for DVB-T)

–Multiple breakout boards on PCB for advanced users
