The physical connections is shown as above. ![图片](https://github.com/user-attachments/assets/16626eb4-130c-40fb-9321-9829a847995a) Then command in terminal. (1st question here): why after...

thank you very much! there is no clock signal detected after i take target device. Hack Index 0--->Serial 59F (Tx); Hack Index 1--->Serial C63(Rx1); Hack Index 2--->Serial F07(Rx 2); ![图片](https://github.com/user-attachments/assets/67a513c8-c8df-448e-904b-fcf4e74f0ba5)...

![图片](https://github.com/user-attachments/assets/aa7f8c42-7156-4a48-ad8a-73a06f7c70aa) Hi @martinling This is the two slave hackrf one to receive signal, do you know why the left is so different with right? right is perfect i think. Do...

If I just connect the p15 and p16 to make the synchronization, no connection between CLK_IN and CLK_OUT, there is just a sampling difference. So this is feasible for synchronization...
