Hi Dave. You can always load an older FW first, and then load the Modifyed one. BR Stig - OZ3XO.

I am trying to set up an ATU-10 by modifying the firmware to set the min tuning power to .4 watts, set the Delta SWR to 2.0, and set Auto mode Off. I have modified the firmware hex file, recalculated

Bill, How do you use that extra board with the 40 pin ZIF socket (jumper settings etc)?? I have not found a use for that on mine that actually works. Thank you. Jim Pruitt WA7DUY

I bought this one and it works well with MPLAB IPE version 6.20 software. ?I used 4.75 volts for the 16F1938 PIC. https://www.ebay.com/itm/331901057989?_skw=pickit

Hi Gabe, I¡¯m using the ATU-100 icm an IC705, 10 Watt Output. The IC705 has a tuner socket which looks at tuner power-on before providing a tune command. The ATU must already have power, if not, you
