There’s talk of a wide band “get around” on the VHF/UHF portion of the FT991/A.. well I dont want to be the bearer of bad news! BUT!!!!!! if you change the band from EU to USA it is a ONE WAY TRIP! it will wipe out a lot of your RX frequencies leaving you little or no option other than a full hardware wide band mod.. It could also wipe out the 3 year warranty instantly..
It is blooming frustrating not being able to wide band the VHF/UHF portion of the radio but it simply is not possible without some form of compromise. changing the radio from EU to USA spec may also de value your radio..
