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.
