Here’s the SV1EIA usb2sdr board controlling the Si570 chip on the vfo kit from K5JHF/K5BCQ, the MCU and display unit are of course removed. And the Si570 board is clocking the LA6NCA QSD unit. I haven’t calibrated anything yet, but it works fine.
Got a new gadget in the mail today. Its the USB2SDR board by SV1EIA . Will for sure be busy testing this nicely build board for the next few days.
I’v just tested a new Tayloe Quadrature Product Detector and Preamp made by LA6NCA Helge.
As the video show. I have down converted the 1st IF from the FT-1000d to somewhere around 460KHz and fed the signal to the product detector.
