Good Evening Everyone,
It looks like this thread has kinda died a bit. I am still without a fix for my issue. I tried again to updated the firmware this evening and still ran into issues above 300mhz. I calibrated it (see photo of correction turned on) and the photo of the version.
Anything beyond the 0.2.x firmware is causing the issues, since 0.1.1 works just fine. I have seen other people have similar issues with the new firmware on this group.
