Monarch flight intercepted by Rafale
I wonder if it was the same one that flew at great speed underneath the 757 that I was in somewhere near Paris at about that time, if so great to see you guys, oh sorry that won't make the papers, so there I was thinking I was going to die & will be suing you for £lots

If it was an 8.33khz frequency (which the French use a lot), it's easily done! On some radios, you might dial up the correct frequency, but unless you switch the radio to 8.33 (not all radios have this 'murphy') you ain't gonna get nothing.

Don't we all, wiggy? ![Bad teeth](https://www.pprune.org/images/smilies/badteeth.gif)
Just realised chevvron is referring to 8.33kHz channel-spacing on the congested VHF AM air-band frequencies. It's been 25kHz since the 1990s (was 100kHz when I was a rookie, then 50kHz...), so 8.33kHz should triple the number of channels available:
8.33 kHz channel spacing below FL 195
(The above info is for lower airspace, but see paragraph 1.2)

Certainly the Rockwell-Collins RTU-4200 series used in some aircraft has a 25 / 8.33 selection option for VHF Comm. Not a 'switch' as such, it's in one of the sub-menus accessed by the relevant Line Select Key.
