ATU-100 tuner not working (build)


 

Hello,

I built the tuner and purchased a separate case for it. It powers on, but I am not getting any readings other than all zeros (SWR, etc).?

I checked all torroids for continuity and read somewhere else where someone had to scratch the paint off the case to get good grounding. I did that as well without success. I am also powering the unit with 12VDC per the manual.

Any other ideas to help troubleshoot? Any help would be appreciated.

Thanks,

Ryan KF8IV
