The IC-9700's Firmware has been updated to Version 1.41. This was released on the 6th of April. I just noticed this release by chance. Note also that the CS-9700 programming software has also been updated to Version. 1.40. (This was released on the 22nd March.)
This is the first time that I have turned the radio/s on in a long time, and just to do the firmware update!
