RX-666 ADC SDR Receiver Radio 1KHz-1800MHz 16Bit Sampling 32MHz Real Time Bandwidth TCXO 0.1PPM

Specifications:
- Model: RX-666
- Size:110*85*25mm
- High performance, high dynamic, high sensitivity, no mirror image. Shortwave 32M at a glance!
- Support for software HDSDR customized version, SDRSHARPER customized version
- USB3.0 interface power supply (spare external 5V power supply / no external power supply required)
- Dual antenna interface: LW / HF and V / UHF (interface type: SMA outer screw inner hole)
- Frequency range: 1KHz-1800MHz (guarantee index 1KHz-1500MHz)
- Stainless steel housing
- Heat dissipation method: shell contact passive heat dissipation

Package Included:
- 1 x SDR Receiver Host
- 1 x USB 3.0 Data Cable
- 1 x Software (provided network disk download)

Operating Environment Requirements:
Support for windows 7, win 8, win 8.1, win 10.

The computer performance is based on the desktop computer: i5 3570 4G memory can run smoothly, 32M bandwidth USB3.0 data, there are certain requirements for computer performance. Multiple machines can be connected to a computer at the same time to run in different frequency bands.

Advantages:
- 1KHz-1800MHz. No mirroring.
- ADC adds anti-jitter, anti-interference functions, SMA dual antenna interface, USB3.0 direct power supply. Excellent performance indicators, stainless steel laser cut shell, stainless steel hexagon socket screw fastening, heavy and heavy, strong texture.
- 16bit ultra-high sampling, 32M bandwidth.
- ADC chip uses LTC2208, 16BIT 32M direct sampling, high sampling bandwidth of 32M! The rate of LTC2208 is much higher than LTC2217, the noise is also 2db lower than that of LTC2217, the throughput is very large.
- It is necessary to use a high-performance computer equipped with USB3.0 interface to run it smoothly.

I bet that's a Devil of a receiver Peter.
Good DX.

Not bad value for £166 if it works well.

Update: It appears there is a snag, it won't cover more than 10MHz above 30MHz

Quick update:
– the seller answered back saying that the upgraded crystal is the 0.1PPM TCXO
– the same AliExpress store has also the (better named) RX888 SDR receiver: https://www.aliexpress.com/item/4001294301962.html
– the RX888 too is derived from Oscar Steila’s BBRF103 design (it is also mentioned in their description) – in this one it looks like they added heat sinks to the ADC and the USB 3 controller; the case too is a big heat sink
– since it seems both SDRs use the R802T2 tuner for VHF/UHF, the bandwidth above 30MHz is limited to 8-10MHz, which means they probably cover only half or less of the FM BC band
– as per the USB 3 throughput, if they use Cypress FX3 SuperSpeed USB 3.0 peripheral controller, they should be able to stream up to 5Gbps, which should be plenty for a 32MHz sampling rate (I think it comes to about 1Gbps at 16×2 bits per sample)

Bjarne Mjelde (Norway) has done an evaluation. The PDF is available on here:http://arcticdx.blogspot.com/

You will need a downconverter for 32MHz on the FM band eg Perseus FM+ if you have one in a drawer somewhere.
