Direct sampling RTL-SDR TECHNICAL SPECIFICATIONS
Fully assembled and ready to use
Uses RTL2832U+R820T2 chip set.
[R820T2 tuner has slightly better sensitivity than the R820T and also works better at frequencies around 1.5 GHz. 100% compatible with software for the older R820T.]
100KHz to 1766MHz, operating frequency
1 PPM temperature compensated oscillator (TCXO)
[Accurate tuning and almost zero temperature drift (2 PPM initial offset, 1 PPM temperature drift)]
Covers all HF amateur bands
Covers VHF & UHF bands from 24-1766MHz
Up to 3.2 M Sample rate. (~2.8 MHz stable)
Receiver modes AM, NFM, FM, DSB, USB, LSB and CW
HF Shortwave Q branch direct sampling
Note: depends upon the SDR software used with the receiver
8-bit ADC giving ~50 dB dynamic range
50 Ohm input impedance
SMA golden antenna connectors It is also more durable and has lower insertion losses
Aluminum enclosure screened panels
Small size board
Freeware software
Independent antenna inputs for Shortwave and VHF
USB computer connection (mini usb) Powered by common USB
All specifications subject to change without notice

Receiving LF/MF/HF (0 - 30 MHz)
The HF band antenna must be connected to the Ant input port.
Signal receiving HF band needs to meet the HF Antennas such as Long Wire, Random Wire, Dipole etc..
To have a good effect it needs matching antenna.

The program of SDR # with RTL configured to direct sampling of the signal Q, as shown in the following figure. (Left Figure)

Operation on VHF and UP:
The UV band antenna must be connected to the Ant input port
By default the RTL-SDR’s gain is set to zero. Increase this gain by moving the RF Gain slider up, or by turning on Tuner AGC. (Right Figure)
