Hi Europa48,
The short answer is probably "yes", based only on our local situation where as
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.
Therefore I have Aberdeen Radar 134.1 MHz permanently in the list of memories,
which causes the radio automatically to operate on 25 KHz mode only when
accessing
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.
If I were to change the radio to 25 KHz mode, then the selection knobs would
operate
in 25 KHz steps, which would be unwise because almost all airfields and
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.
I'm not an expert in this field, but I suggest that you should leave your radio
set in 8.33 mode and put any old 25 KHz frequencies into memory.
