Hello All
According to the attached MARS Mod, a solder bridge is required for JP3003 on the CNTL-UNIT which can be accessed opening the "bottom cover".
Attached is also a photo of the FT-991 with the bottom cover off, and the CNTL-UNIT is not apparent... the large IC that is showing on the photo of the MARS document is nowhere to be seen...
Has anyone been able to pin-point the circuit where the JP3003 is located ?
Thanks!
