Description
This is an RTL-SDR software defined radio receiver with RTL2832U ADC chip, R820T2 tuner, 1PPM TCXO, SMA F connector and aluminium case with passive cooling. Tunes from 100 kHz to 1.8 GHz with up to 3.2 MHz (2.4 MHz stable) of instantaneous bandwidth. (HF works in direct sampling mode). Perfect for use as a computer based radio scanner with free software like SDR, HDSDR, SDR-Radio, GQRX or SDR Touch on Android. Works on Windows, MacOS, Linux, Android and single board computers like the Raspberry Pi.
Great for many applications including general radio scanning, air traffic control, public safety, ADS-B aircraft radar, marine AIS, ACARS, trunked radio, P25/MotoTRBO digital voice, POCSAG, weather balloons, APRS, NOAA APT/Meteor M2 weather satellites, radio astronomy, DAB, or as a low cost panadapter with a standard ham radio.
This model has several improvements over other models. It uses the improved R820T2 tuner, a 1PPM TCXO, has better components, a redesigned PCB, cooling improvements, extra ESD protection and an SMA F connector. It also has a LNA(Low noise amplifier).Requires USB 2.0 or newer. Features on DVB-T +DAB+FM+SDR RTL2832U R82T2 TCXO + HF. Please feel free to contact us for support.

Why you need TXCO temperature controlled oscillator?
As the dongle heats up from use, the oscillator will experience thermal drift, causing the frequency offset to change. The TCXO should be immune to this problem due to it’s temperature compensation circuitry. To test the temperature compensation, we cooled both a TCXO dongle and a standard dongle down in a refrigerator first to simulate cool climate conditions. We then measured the change in PPM offset after 30 minutes of dongle operation. As expected, the TCXO had almost zero drift after 30 minutes (<<1 PPM), whereas the standard dongle had a drift of about 6-7 PPM (approx. 1 KHz drift).
TCXO Oscillator -Frequency drift after 30 minutes
Standard Oscillator Frequency drift after 30 minutes
Features:
<1 PPM temperature compensated oscillator (TCXO) ? Accurate tuning and almost zero temperature drift (2 PPM max. initial offset, 0.5-1 PPM temperature drift)
SMA female antenna port ? Generic dongles use the less common MCX or PAL antenna ports. SMA is more common, so more adapters and antennas are available for it. It is also more durable 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 choose the Q-branch mode. There is a built in 25 MHz low pass filter, but 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 stock with an aluminium case and passive cooling via two cooling fans. And the PCB board is designed especialy for passive cooling design 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 choke on the USB line to reduce USB noise, a much improved PCB design for significantly less internal spurs and noise, various break-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 below 24 MHz runs in direct sampling mode)
With LNA, low noise amplifier for the HF signals. 10 times amplification than normal HF reception.
Great for many applications including general radio scanning, air traffic control, public safety radio, ADSB, AIS, ACARS, trunked radio, P25 digital voice, POCSAG, weather balloons, APRS, NOAA APT weather satellites, radio astronomy, meteor scatter monitoring, DAB, or for use as a low cost panadapter with a traditional ham radio.
