I want to install a dedicated aircraft band scanner as well as one that can monitor Cal Fire in the 151 - 160 range. The Uniden website states that the 15x channel spacing is 8.33 khz which is the European Standard. Does the 15x have a setting for 25 khz which is what's used in the United States? Similarly, does the 15x have a setting for 12.5 khz for the 151-160 range? Both Cal Fire and San Bernardino County Fire have VHF tactical frequencies that use narrow band.

VHF 151-160 should be 7.5 kHz steps, not 12.5 kHz. You're confusing the VHF air band 108-137 with Cal Fire airborne ops in the normal public safety VHF block. You can set 108-137 at either 25 kHz or 8.33 kHz, but leave 151-160 at 7.5 kHz.

Band Defaults basically, this setting allows you change the 'Auto' values you can select while programming frequencies, searches, etc. to whatever you feel 'Auto' should be for each band (vs. the radio defaults). Since all of the step and modulation settings default to 'Auto', this allows you to skip those settings when programming. Note: This setting has no effect on service searches.
Scroll to the band you wish to edit and press E/●. Refer to Auto Step Size chart to help find the bands in the menu.
At 'Set Modulation' scroll to AM, NFM, FM, WFM, or FMB (Broadcast) and press E/● to save and exit.
At 'Set Step' scroll to Auto, 5, 6.25, 7.5, 8.33, 10, 12.5, 15, 20, 25, 50, or 100 kHz and press E/● to save and exit.
Scroll to any other bands you wish to edit and repeat. Press MENU to return.
and that is from

Yeah, that 5 kHz for 150.8 - 161.995 is old, it should be 7.5 kHz now post-narrowbanding in order to tune to the newer channels like 154.4075. As I stated in my initial reply.

I also think you’re confusing channel steps with bandwidth.
If I am not mistaken the two are synonymous in this case. The bandwidth of the audio can consume up to 25 khz. Another "channel" may be created above or below the channel in question 25 khz apart. Correct?

You'll have to forgive me for being new. But I wasn't "confused" about anything. If the Uniden manual needs to be updated then so be it. I simply asked a question for clarification. When somebody responds and says something like "you are confusing" it feels like I should not have asked to begin with; like I should have known. Thank you Wtp for posting what I was going to post from the manual. The 151 - 160 range is mixed.

You perceive an insult where none was intended. Twice I provided you with the correct information in response to your inquiry. Do with it what you wish, I'm moving on.

Bandwidth isn't dictated by channel spacing. Your scanner doesn't change it receive bandwidth capabilities based on the channel spacing.

And no LMR signal (in the US at least) is actually 25 kHz wide. About the widest I recall is iDEN, which was 18.54 kHz. TETRA may be the same or pretty close.

Being new I acknowledge I have things to learn. But it is intimidating coming to a group such as this with very knowledgeable people and even though they know you're new they use phrases like "I think you are confusing..." I can't confuse what I haven't learned yet. I could have been more clear that I know that the full 25 khz is not used. My frame of reference would have been CB radio where the channel spacing is 10 khz but the bandwidth utilizes no more than 8 khz. As I work for my ham ticket these topics have not come up yet. So I ask questions. If I get something wrong I appreciate it when I'm guided to the correct answer as you did. As it turned out it had to be acknowledged that the Uniden manual online is outdated but that was my point of reference. I've been sufficiently educated at this point. On this topic anyway.

You've been a member here for 3 years, and I've never interacted with you previously. I couldn't possibly know or even guess that you were new to any of this. If you don't want people to make assumptions about your level of knowledge, then you should likewise refrain from assuming that any of us would inherently know that you're new to the hobby. 🤷‍♂️

I am nearly 70 years old and for I believe the fourth time I'm writing this, I'm new to this. I don't believe it's your job to scold me. I think this is the point where as gentleman we drop this. This is not healthy dialogue.
