This post asks a question pertaining to the Uniden Bearcat BC95XLT scanner.

Sometimes, after a frequency with an active transmission is found during the
search (Func + Src), it has a 25, 50, or 75 to the right of the frequency.

For example:

411.768 75
413.437 50
415.106 25

(The 25, 50, 75 is smaller than the main frequency numbers.)

Sometimes the numbers can also be seen cascading 25 - 50 - 75 in rapid
succession during the search--mainly through the 4##.### frequencies when
frequencies have not yet been found during the search. Also, when searching
through the 8##.### and 9##.### frequncies, only the 50 blinks on and off
during the search, and occasionally an 8##.### or 9##.### frequency will
have a 50 after it after a transmission has been found during the search.

Other examples:

931.812 50
936.737 50

Hopefully, my explanations have been clear enough, along with the examples
provided.

Are these just additional frequency decimal places (i.e., 411.768 75 means
411.76875) or do these mean something else? (The manual shows these
indicators as part of the display, but does not appear to explain what they
actually represent.)

Thanks in advance for any information regarding these 25/50/75 display
indicators.

Yes they are additional decimal places.

The scanner seems to use 6.25 kHz steps on the 400 MHz band ie. during
search the actual frequency is incremented 6.25 kHz (0.00625 MHz)
and goes like this:

411.00000
411.00625
411.01250
411.01875
411.02500
411.03125
411.03750
411.04375

etc.

On other bands like 800 and 900 MHz it seems to use 12.5 kHz steps:

931.00000
931.01250
931.02500
931.03750
931.05000
931.06250

So the indicators simply show the fourth and fifth decimal places.
