Edit:? I was trying to use the wrong file.? I downloaded the zip files and everything worked fine.? ?The firmware is upgraded and modified for QRP.? ? An initial test shows the tuner does work, although not quite 100% of the time.? Will have to do some more checking when I get a chance.
Hi All,? I am new to this group, but not to the ATU-100.? ? A little over a year ago I built one of the ATU-100 (extended) tuners, but recently purchased a second one to modify for QRP use.? ?As several others have reported, the tuner came read protected, so when attempting to read the microcontroller all I get are zeroes.? ? I have been to GitHub and have seen all the files, but I don't know for sure which one to use for firmware version 3.2.? I have watched the videos on doing the QRP mod, and have read many messages, but have not seen anyone supply the file name I need to download.? ?I am assuming the file ends with a .hex extension.? ?On GitHub, I downloaded? ?atu_100_fw_EXT_32.hex, but when I tried to import it in the PICit3, it reported an error importing the hex file.? ?Is this the correct file to us, and if not, which file should I be looking for?? ?Also, I believe I read that you can just write the new firmware over the old, without having to erase first - is that correct?? ?I am new to this type of firmware upgrade (have done a little on a uBitx, but that's a little different) so any help would be appreciated.
Thanks,
Jim? (w8ykg)
