25 khz freqs will still be 25khz freqs and will be selectable as before on your new 8.33/25khz radio(unless you have an IcomA220 which is a bit more difficult as explained in earlier post)
Good reading here to explain:

The table requires a good look to understand that your new 8.33 radio is in fact dual 8.33/25.....and your old 25 will work just fine on those freqs....which begs the question as to why we are not supposed to use them!
Oh... and CAP1573 says
"The licensing fee charged by Ofcom for an 8.33 kHz radio licence will be significantly less than the 25
kHz licence fee, due to the reduced bandwidth occupied." Yea right....... more like blackmail!
I think the key bit in the article you cite is:
"If you accidentally select
132.005 when you should have selected 132.0
you will be on the right frequency but with a
narrower bandwidth, but the chances are that
you will be able to communicate. But if you
select 132.0 when you should be on 132.005
your radio will be in 25kHz mode and you are
likely to cause interference on several 8.33
channels and you may hear transmissions from
adjacent frequencies."
If you can communicate with a 25kHz Ground Station by selecting the nearest 8.33kHz frequency, then maybe the current ICOM A220T is set up the best way. You can continue to operate in 25kHz mode until the end of this year and then switch to 8.33kHz mode so that you do not interfere with any distant ground stations on adjacent 8.33kHz frequencies when you transmit.
If communication with a particular 25kHz ground station fails, you can temporarily switch back to 25kHz mode in the air. This will no longer be necessary when all ground stations eventually switch to 8.33kHz.
Is this summary correct, or have I missed something?
