This is a very interesting SDR transceiver. There are two independent RX and TX. RX is powered by two powerful 16 bit LTC2208 ADCs with 125MS/s sampling rate. TX contains 14 bit AD9767 with 125MS/s sampling rate. Both RX and TX are capable of operating in the frequency range of 10kHz to 60MHz. They can cover all HF bands up to 6m.
SDR CPU is powered by dual core ARM Cortex A9 together with FPGA Xilinx Zynq 7010 SoC. Data connection over 1Gbit LAN port.
This SDR could be used with popular SDR software like HDSDR, SDR3, PowerSDR etc. HW is similar to the RedPitaya board. Thanks this, there is great support by Pavel Demin and his firmware. It supports CW, RTTY and DIGI skimmers. This SDR has two independent receivers and thus allows experimentation with Diversity RX - the possibility of eliminating QRM, phasing of RX antennas, etc. See our technical blog posts for more information.
With our range of pre-configured SD cards, you can save time and get up and running as soon as you switch on the SDR.

Instruction manual
Please read this manual before switching on the SDR. In addition to important information about the power supply and the SD card, you will also find information about the SDR website and tis administration.
Recommended to buy:
Please also protect the receiver and ADC inputs. It can be destroyed by too strong single. Threfore I recommend to connect an RF limiter to the SDR input. We offer a wide range of such products.
Pre-installed SD cards
To make sure you don't buy the wrong SD card, or to get you started with SDR as soon as possible, we offer pre-installed SD cards. Some require no modification, the FT8 stand-alone requires a text file modification with your CALL and LOC. See our technical articles for more information.
The pre-installed SD cards can be found at our website.
Example of use - PowerSDR (Charly25):
You can use this powerful PowerSDR program to listen on the HF bands and using its features.
A very interesting feature is Diversity receiving- where you use both receivers and phase them together. You can shift the phase 360 degrees and also the amplitude - this solution offers more than QRM killer boxes, noise killers and expensive phasing boxes. You can use this feature to reduce local interference, but also to phase RX antennas to achieve interesting directional characteristics!
For more information see the technical article.

Example of use - CW, RTTY and DIGI skimmer at PC:
The receiver can provide IQ data from 8 band receivers to a PC. There you can run CW, RTTY and DIGI skimmer servers. These can send data to the Reversebeacon Network, PSK Reporter and others. You can also record whole bands, listen to them and tune them later. Here is the link to the article.
Example of use - Stand-alone FT8 skimmer in TRX-DUO:
A very interesting option is to run a 8 band FT8 skimmer directly in the WEB-888. With this option you get a skimmer with very low power consumption and size. You can change the bands according to time: day, night and grayline.
See our technical article for more information.
Very important
Please note two important things:
1. Use a sufficiently powerful power supply I recommend 5V 2A. At the same time, the power supply may not be well filtered and may produce RFI.
2. Use the SD card recommended in the instructions, or buy a pre-installed SD card from us that has been tested.
3. Be careful not to overload the SDR and ADC inputs with a strong signal, such as your own transmitter. This can destroy the ADC and degrade the SDR. A new 16-bit ADC costs almost as much as a full SDR.
We recommended and RF limit as protection. Several can be found directly in our offer. Others are already part of our more complex devices.
4. SDR cooling The box does include a fan, but when using the SDR 24/7 or as a stand-alone skimmer, the CPU and converter get hot. Poor cooling leads to their destruction or reduced lifetime!
It is highly recommended to add a fan to improve cooling and avoid destroying the SDR in case the internal fan fails!
Therefore, please ensure sufficient cooling and check the fan regularly to prevent it from cooling due to dust.
⚠ There is no warranty for damaged ADC and fan!
