Checking an ATU-100 FW Ver. 3.2

#atu-100

James All Messages By This Member #1429 Greetings, Is there a written point to point test menu for checking problems for an ATU (China)100? I built it over a year ago and no problem, including dropped software the unit to recognize my QRP radios.? I am now using a 9:1 UNUN random wire at my shack and had some RF get loose in the shack. I resolved that completely, but I believe my unit is not working correctly now. Seems like less relays working to change the load to the radio.? A short version of how to check would be appreciated. The Firmware version is pictured below. Thanks for any help Regards to all 73 James
David Fainitski All Messages By This Member #1430 Hi. There are 2 test firmwares , you can use both of them to find burned transistors or bad soldering. "Fast test" just turn all the relays on and you can check everything with multimeter. "Manual test" allows you to operate all the relays manually.?
James All Messages By This Member #1432 David, Do I need to open the firmware to activate the tests or just press the Green reset button and check to see if all the relays are on? How do I check manually? My documentation was a minimum, basically a schematic, list of the parts, coils sizes and 1 picture. I will say it has run flawlessly for a year.? Thanks for the help David.? Cheers James and Dawn KB9NBL and KB9PIY
David Fainitski All Messages By This Member #1435 Hi, James. You have to flash your tuner with programmator Pickit3 and special testing firmware you can found on GitHub. After test you have to return to working firmware back.?
F6GWE All Messages By This Member #1436 Hi Group , David, James ?The test? firmware is only for? qrp ATU-10? not ATU-100? ?I could be wrong but I have never seen test firmware for ATU using 16F1938 73 qro Patrick
James All Messages By This Member #1437 David and Patrick, I have attached a link from IK3SSG and his work on getting the ATU-100 to QRP levels. This is what I did a year ago. I do have a Pickit3 to use to reprogram if needed. https://youtu.be/dPys_-_wPcQ Let me know your thoughts, I have used this ATU-100 for over a year with no issues until now and I believe very close output for SWR and Watts according to my a secondary mfj meters. Thanks for your help James
F6GWE All Messages By This Member #1438 Hello James, This is perfect you are right, I did it too. this is for ATU-100 I just said for ATU-100 modified or not, there is not test firmware. Test firmware is only for QRP ATU-10 this is an other project. 73 Patrick
James All Messages By This Member #1439 Edited Okay, I will try to test when I get back home. Regards Cheers 73 James

James All Messages By This Member #1444 Thanks for the update Tony. I was just wanting to confirm what was being put on GITHUB James
David Fainitski All Messages By This Member #1446 Hi, folks I forgot, test firmware now is a part of working firmware. Power on your tuner with pushed down Bypass and Auto buttons for fast test or all 3 buttons for manual mode test. This should be in the manual for tuner.?
Katsuhiko #1448 Thank you for your answer. However, the hardware of the ATU-100 is normal. Because it works fine with the original firmware (N7DDC version). 2022年6月5日(日) 11:23 David Fainitski <rolin791@...>: toggle quoted message Show quoted text Hi.
