When set to 8.33 you select channel numbers and not frequency:
Channel 134.100 is 134.1 MHz 25 KHz
Channel 134.105 is 134.1 MHz 8.33 KHz
You do not need to set your radio to 25KHz mode access the original 25KHz
frequencies,
just dial in the appropriate channel number and it swaps from 25 to 8.33
spacing automatically.

soon as we leave our airfield 8.33 channel, we must talk to Aberdeen Offshore
Radar on frequency 134.1 MHz which is on the original 25 KHz spacing. My Icom
radio is quite difficult to switch between 8.33 and 25 KHz modes, causing too
much distraction while attempting to do so.

a specific memory. If I then choose to turn the two selection knobs for
some reason, they resume functioning in 8.33 directly without any input from
me.

airports have gone over to 8.33 channels. The only reason that Aberdeen Offshore
remains on 134.1 MHz is because it's Rebro, having 3 additional satellite
rebroadcasting stations on such remote locations as offshore platforms. To
change
all that would be a considerable challenge.
