Just in case anyone has not seen, the CAA have published the new "sporting" 8.33Khz frequencies (CAP 1606).

For the gliding frequencies
129.900 becomes 129.905
129.975 becomes 129.980
130.100 becomes 130.105
130.125 becomes 130.130
130.400 becomes 130.405

So if trying to contact a gliding site then 129.980 or 130.105 are the most likely. The BGA has asked for 4 more frequencies, likely to allocated this Spring & will publish revised guidance on usage at that time.

Note also that SafetyCom is now 135.480

Why ? If you select 135.475 MHz on a 25 kHz radio then that will still work perfectly as 135.480 has an identical frequency of 135.475 MHz.

To the OP, it's kHz, not Khz.

I've never quite understood the difference between frequencies and channels, as riverrock says.

All radio transmissions use a frequency, so why can this term no longer be used?

Yet CB (and marine radio) were on "Channels".

What's the difference?

Enquiring minds need to know (at least this one does)!

The new numbers you type into your radio no longer (necessarily) directly represent the frequency you are listening on, but whether you are listening with a 8.33kHz filter or 25kHz filter.
type channel 135.475 in and you are listening to frequency 135.475 MHz with a 25 kHz filter (same as before)
type channel 135.480 in and you are listening to frequency 135.475 MHz with a 8.33kHz filter.

The tighter filter means that three channels can be allocated where previously there was one.

This stuff is confusing to a bear of little brain like myself....so i can merrily pop over to blighty in my legal french chariot and use the same radio i used last year "sans problem" on these newfangled frequencies then?

So why all the fuss and expense changing everything....???

But isn’t that illegal now?

Yes, whatever your reg.
