ATU100 intermittently switching to auto on TX #atu-100


 

Hi all -

My ATU100 is working great - I think it will tune a rusty nail - I was able to tune my 80 meter off center fed dipole on 160 - something I was unable to do with my other name brand tuner!? And then I made my first ever top-band contacts - whoo hoo!

One issue though is the tuner will very occasionally switch in to auto mode on Tx - without pressing the button.? I have caps to ground on the Auto and Bypass buttons.? ?The enclosure is one of the 3D printed plastic ones.? Is some shielding needed or recommended?? Anything else to look for?

73.
