Hello,Yes, I've tried applying 10-20w of power without success.I'll check the diodes when I get home from work and let you know. Thank you for the input.Ryan KF8IVSent from my Verizon, Samsung Galaxy

hi Ryan, sorry, but first the question: do you apply more than 5W HF (CW, AM or FM) to start tuning? Before changing the diodes, you should make some little measurements with an Ohm-meter to see, if

Hello,Thanks for responding. I checked my board and per the schematic and parts listed on it, it states that it has BAT41 diodes installed. They are both matching black diodes on the underside of the

hi Ryan, perhaps the diodes at the bridge don‘t work as they should. If possible change them both(!) to BAT41 or equivalent. There were multiple issues with this (search for ?BAT41“ ). Hope, it

Hello, I know it's a while ago, but did you ever get your ATU-100 to work? I am having the same issue with mine and looking for any troubleshooting. Thanks

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

I went through the same problems with a Chinese Clone Pict 2 programmer and Win 7.? I documented how I got it working (message #2111).? Hope this helps.

Thank you for the tips. I also suggest this YouTube video https://youtu.be/bcwcDPU5PLQ which explains winding of the toroids and the air inductors, and a way to use a piece of coax on each side of

Got my ATU-100 on Amazon a week ago and I have done extensive testing. The tuner works very well with the little 45 watt amp. I opened it up and looked inside and it is very well constructed. I am

Thank you. I had found the technical description and schematic, but couldn't find an assembly manual. The YouTube video by va3hdl looks good. 73, Al - va3iaw

Hi Allen, you can find schematic and manual, but assembly is the simple soldering components to the board.

It's on N7DDC's github site: https://github.com/Dfinitski/N7DDC-ATU-100-mini-and-extended-boards 73 de va3rr

The ATU-100 kit I bought from AliExpress arrived without assembly instructions. Can anyone provide me with the assembly instructions or point me to them?? I have searched online in vain. 73, Al -

Hi guy's, Anyone have a good/reliably source to buy an N7DDC 100W tuner? From what I've read here, most of the sources in Ali, Amazon,etc almost all come with fake toroids, bad relay's, diodes on the
