Hello, it looks very promising. Soldering small smd components is not a problem, I have a microscope. Now I have two SDR-Micron versions, one with ADS9629 and R820 BPF board and the other with ADS6145

Hello, Radek The R820 board was rejected form project. I just received PCB from China and started to assembly new VHF board. Very small components, need to use a microscope.

Hello David, any news regarding 50 MHz - 6 GHz extension board for SDR-Micron? I noticed that the R820 extension board project was abandoned on Github. thank you for answer Regards Radek (nickname

You can save more power using 1.8V DC/DC converter for ADC supply.

Yes, I am also worried about DC / DC interference, so I only use it on the 1.2V power supply of the FPGA. At present it looks like the frequency spectrum is clean

Nice job ! The power consumption is not too small, probably that is bad idea to use DC/DC converter here, it can become an interference source.

I redesign the pcb use ipex and RF cable to connect Micron and Tuner board.The 1.2V power rail to FPGA is changed to DC/DC supplied This the power i mensured from usb. My ADC chip is AD9649-80 Only

For the R820T2 tuning board, I did a simple reception test. The overall effect is close to my AIRSPY R2. The reception performance is good. I did notice the problem that the noise increased at

我很高兴我成功制作了SDR

Hi Sir， Good concept, looking forward to the new version of VHF Receiver board, thank you for your efforts，In addition, since the received signal input is up to 6Ghz, in fact, PCB layout and

Hello. The additional frequency range are realazing very easy with cheap components - couple switches and HPF. See the picture how is forming bands on that board: The SDR Micron has 30 MHz bandwith

In fact, because Micron's bandwidth is relatively low, even if the frequency is extended to 6Ghz, which is the same as hackrf one, the actual application will be poor. As for reception, less than 1Ghz

R820T2 is used on airspy, the performance is ok, but the heat is very large, I don't know what problems you have during the test. In addition, you can use the msi001 tuning chip, which is used in

Hello. I have fixed that board, assembled, tested and rejected from project couple month ago. Due to very bad work of R820T. I am working now on other ultimative 50MHz - 6GHz extension board for

I noticed the photo of the R820T filter pcb board posted. The chip of R820T2 seems to be mirrored. Is the board of R820T2 ready?

3 RX ports: RX1, RX2 and RX3 (optional) R1 used in the RXTX switch connected to the TX antenna RX2 and RX3 connected to receiving antennas for phasing or diversity

Hi David, Would you consider a new revision in the future with the help of volunteers assigned to tasks such as documentation (schematics, howto, guidelines), bring-up, boot-loading, Verilog

Hello. This project has been completed. Everyone who wanted already assembled it.

It seems to be a great project and well designed. It is complicated as expected. Is it active, please say yes :)

Hi David, My Micron using ADS6143. I masseur again. About 160mA when inactive mode. About 360mA when active mode. I don't know why.....? When 0.1uF and 1nF were jumpered, the sensitivity of the low
