Thank you Bjorn.? ?I have uploaded that fix.? Thanks for finding this. Dave

It?s for ATU-10 (QRP) on Github.

Thank you.

I downloaded the MPLAB code from WA1RCT github repository ( https://github.com/WA1RCT/N7DDC-ATU-100-mini-and-extended-boards ) today but the power measurement did not work. I tried the change on line

https://github.com/Dfinitski/N7DDC-ATU-100-mini-and-extended-boards You can find it there

Oscar, where did you find the "Manual_Test.hex" file for the ATU-100. I am having problems and would like to try this file.

I just received my assembled atu-100 and am looking for some instructions.? It only came with a power cord, no manual.? I have watched a few videos and can set it up and use tune function without a

Hi . You will need all 3 buttons to operate that FW. Tune, Bypass and Auto.

Hello all, I have been reading many messages for a while, but I have not found a simple explanation of the use and measurement after loading the file "Manual_Test.hex". If someone could give me a

Magic ! Patience?, my arse, I want it now.....

Thanks for the test.

You can see the prototype here http://www.sdr-deluxe.com/publ/avtomaticheskij_antennyj_tjuner_s_avtonomnym_pitaniem_prototip/1-1-0-55

Thanks Dave. John

Hi John If you have 7.85V to the tuner you will have to increase the voltage to at least 10V I have set mine to 11V Thanks Dave

Scott Do you recommend getting these units from newdiytech rather than from aliexpress ?

Thanks for the readings Dave. I have put a switch inline with the positive wire from the battery and then other side of the switch goes to the circuit board. My volts are; Switch + (from battery)

I would not think so. There are two coils in a latching relay, and only one in a conventional relay. So the electrical connections are not there, that would require a new PCB. Max

Hi Amanda The 5 turns on the tandem match transformer is so the unit tunes from about 1watt, Thanks Dave 2E0DMB [email protected]> wrote:

Although it should be technically feasible, financially it's not likely to make sense. The latching relays represent the biggest chunk of the cost of a new kit, so you won't save all that much money.

Hi John My battery ? is now fully charged and the board has stopped taking any current from the usb and the charging red led has gone out and the green led has now turned on, The battery voltage
