RTL-SDR Blog V4 R828D RTL2832U 1PPM TCXO SMA Software Defined Radio (Dongle Only)

Description

Includes 1x RTL-SDR Blog brand R828D RTL2832U 1PPM TCXO SMA V4 Dongle.

The best value RTL-SDR on the market! Several improvements over generic brands including use of the R828D tuner, triplexed input filter, notch filter, improved component tolerances, a 1 PPM temperature compensated oscillator (TCXO), SMA F connector, aluminium case with passive cooling, bias tee circuit, improved power supply, and built in HF upconverter.

NOTE: This is the newer V4 design, and it requires updating to the latest drivers to work. Before purchasing, please ensure that you understand that not all applications work with the V4 yet! Compatibility with most popular software is now okay, but some niche programs are still lagging with support. Please consult the V4 users guide for more information.

Please see the RTL-SDR Blog V4 Release post for more information.

At RTL-SDR.com we sell significantly improved premium RTL-SDR dongles but keep our profits low and offer free shipping in order to maintain low retail pricing. We strongly believe that our V3 and V4 dongles are currently the best ‘bang for your buck’ RTL-SDR dongles available on the market. Please see the V3 features datasheet or the V4 datasheet for information on the improvements made, and our V3 or V4 user guide for information on using special features of our dongle. If you are new to RTL-SDR check out our about page first. Briefly, our dongles come with the following improvements:

• <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.
• 4.5V USB powered bias tee – This allows the RTL-SDR to power low noise amplifiers (like the LNA4ALL, HABAMP, RTL-SDR Blog ADS-B LNA) and active antennas through the coax cable. Can be enabled in software (see V3 / V4 users guide).
• HF Direct Sampling Mode (V3) or HF Upconversion (V4) – Listen to 500 kHz – 28.8 MHz with direct sampling on the V3 model, or upconversion of the V4 model. 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).
• Aluminium case and passive cooling – These units come stock with an aluminium case and passive cooling via a silicon thermal pad. This stops reception failing due to heat when used above ~1.5 GHz.
• (V4 Models) – Improved front-end filtering. The V4 model is less prone to being saturated by strong broadcast stations.
• Improved Antennas – We provide an excellent dipole antenna starter kit for newbies. Use the included mounts and extension cable to mount the dipole in good position for optimal reception. Receives terrestrial and VHF satellite signals.
• Various additional improvements compared to other RTL-SDRs – 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, a modified power design for improved long term reliability, modified PLL circuit for better stability at 1.5 GHz and above, and a better LDO.
