Self_test fail?

Hey @Zack, I’m happy to report I get a very similar looking FFT view! Are there any other self test measures I should try, or should just continue working towards getting a strong FM broadcast? Also, do you know off hand if the v1.2 has the loopback control capability? I’m seeing this GPIO error as a result of performing a “Read Values” or “Write Values” in board controls.

Thanks much

AFAIK v1.2 does not have the switches for loopback.

Thanks @andrewback
