I am using the Wspr pico unit.it works OK when connected to the pc. I want to test it under solar power but I am in a geofenced area so it will not tx. I have edited the firmware .ino file to remove my Maidenhead location. I have compiled the file ok . I can upload the file to my pico but after uploading the led does not flash I have had to revert to a usable firmware by uploading the hex file using xloader. Any help? Or is there a pre 0.92 version of the firmware as a hex file I can use to eliminate geofencing altogether
