SDR Receiver V3 Pro with Chipset Rtl2832 Rtl2832U R820T2 for Ham Radio SDR for
SMA female antenna port - Universal dongles use the less common MCX or antenna ports. SMA is more common, so more adapters and antennas are available for it. It is also more and has lower RF insertion losses.
HF reception in Direct Sampling Mode - Listen to 100 kHz - 25 MHz with direct sampling. Simply connect an HF antenna to the SMA port, and the Q-branch mode. There is a built in 25 MHz low pass filter, additional HF filters may be required for optimal performance (e.g. to attenuate strong MW AM).
Better Cooling system, big Aluminium case and passive cooling - These units come with an aluminium case and passive cooling via two cooling fans. And the PCB board is designed especialy for passive cooling by the cooling holes and big aluminum enclosure. This stops reception failing due to heat above ~1.2 GHz
Use R820T2 tuner, higher quality passive components, a on the USB line to reduce USB noise, a much improved PCB for significantly less internal spurs and noise -out pads, improved ESD protection, additional bypass capacitors and ferrite power line chokes, improved front end matching circuit and a better LDO.
Lower overall noise, more sensitivity.Can tune from 100 kHz to 1.8 GHz and has up to 3.2 MHz (2.4 MHz stable) of instantaneous bandwidth. (HF reception 24 MHz runs in direct sampling mode)
With LNA, low noise amplifier for the HF signals. 10 amplification than normal HF reception.
Great for many applications including general radio scanning, air control, public safety radio, ADSB, , ACARS, trunked radio, P25 digital voice, POCSAG, weather , APRS, weather satellites, radio astronomy, meteor scatter monitoring, , or for use as a low cost panadapter with a ham radio.
