Is this system a splinter?

Here are the frequencies:
855.7875* 856.9125* 857.7875 858.8125* 859.7875

I am thinking that since these are frequencies less that 860, this is a splinter system. Is this correct?

This is not a splinter system. It would have to contain at least one frequency that is an even multiple of 12.5kHz i.e. ending in .0250, .0500.... .9750. I don't think "below 860" has to do with it but certain combinations are above or below 866MHz (for now...)

A splinter system is identified by frequencies in the range [851.000 , 866.000) that are integral multiples of 25 kHz. A "non-splinter" system will have a 12.5 kHz offset from such integral multiples. The frequencies above have this offset, so it's not a splinter system.

The system appears to use channel numbers below 352. That is, the highest channel number is 351, so that the highest frequency is found by:

• Base + Step x (Channel - Offset)
• 851.0125 + .025 x (351 - 0) <-- 851.0125 is the base for a non-splinter system
• 859.7875 (the highest frequency listed for the system)

I presume you're referring to this sentence: Splinter systems have frequencies below 866 MHz that end in zero (851.0250 for example).
That means that, on a splinter system, frequencies below 866 MHz will be integral multiples of 25 kHz. A non-splinter system uses frequencies below 866 MHz, as well, but has the 12.5 kHz offset describe above.
