    The "+10kHz" switch is a funny thing. It only gives the operator 5 extra channels within the CB band. Today, just for kicks, I was monitoring and transmitting on channel 18 with the switch on. Some might call that channel 19. I also learned that channel 23 is a frequency between channels 25 and 26. I'm late to the party of frequency assignments.

    Are those 5 extra channels legal? They're not assigned CB channels, but they exist within the legal CB band. I'm not asking because I use them or that I'm worried about the consequces from the FCC-- we all know that's a joke. It's a peculiar situation. Unlike freebanding, these "split" channels aren't out of the band. It's a matter of semantics, I suppose.

    Pretty sure it's strictly illegal

    Those 'in between' channels were set aside for things like garage door openers, RC planes and so on. Some of it was a compromise for the band being taken from the hams, a bunch were using it. If the band plan was setup right, those channels would not be provided.
     
    BTShepp Thanks this.

    Back in the good 'ole days of 23-channel radios, it was pretty common to find 22A in radios like the original Courier 23. I don't know why the other 'extra' channels weren't included, but I suspect it has something to do with the way the frequency synthesis system worked and/or it being more cost effective to use a 24-position channel switch. Those channels have never been legal for CB use, but 22A was quite popular with skip-shooters as it was more likely to be clear, back when many folks were still using 5-10 channel crystal controlled radios.

    The 10 khz switch gives access to the following frequencies:

    26.995 (between 3 and 4)
    27.045 (between 7 and 8)
    27.095 (between 11 and 12)
    27.145 (between 15 and 16)
    27.195 (between 19 and 20)

    Note...any "certified" 11 meter CB does not have these capabilities in stock form. The above frequencies were set aside for RC toy operations.

    Which can be kind of fun if little Jimmy is flying his 27 MC RC airplane and you happen to have a splatter box radio, you key up and cause his plane to do uncommading movements.

    Then again it's a bit absurd and childish to do to anyone unless you know them and are just messing with them in good humour and they understand it as so.

    The CB tech god ... takes his time in responding and if you get out of line, then you get "no soup for you".

    The 10 khz switch by my understanding splits the channel. Anyone on a channel, without the 10 khz will only hear distorted transmission.
