Feb 8, 2010 · FM Narrow / narrowband FM. Typically, FM would be 20 khz or thereabout, and NFM would be 11.25 khz or less. If your scanner doesn't do narrowband FM, it's not a big deal. But if your scanner does have an NFM mode, you should use it on those frequencies that are listed as NFM. That's in a nutshell.

Apr 2, 2016 · "FM was the original FM mode" makes sense when you know the difference between the terms. There is a difference between "FM" and "the FM mode". Clarifying: FM (the designation) was the original FM mode (the modulation scheme). I was not repeating myself in the terms. The terms happen to use the same letters.

Aug 14, 2008 · Hi, I was monitoring the frequency of 155.8425 and am not sure if its FM or FMN. I'm not really familar what the difference is or what they both mean but seem to come in clear set on either one. I think if the frequency would be 155.840 or 155.845 it would be set under FM but I noticed most VHF frequencies with a odd ball number in the database ...

Sep 30, 2017 · FM-N stands for FM narrow band.This corresponds to a 2.5 kHz deviation. FM corresponds to a 5 kHz deviation. Most repeaters are still 5 kHz although with spectrum crowding, we will see more 2.5 kHz repeaters to allow more repeaters to …

Mar 29, 2017 · Almost all Public Safety and Industrial/Business stations in the 138-174 and 450-470 MHz bands that are analog FM were required to use NFM (5 kHz deviation) on 01/01/2013.

Baofengs seem to come set up as FMN by default and have a lot less volume than a radio properly configured. There are very few areas using this new FMN mode for simplex or repeater operation...so anything you can legally transmit on will be fine. The reception will work, though at reduced volumes.

Feb 27, 2023 · Can someone tell me what the mode means on frequency database. What is difference between p25, fmn, rm,dmr. Most in my arra arr fmn or rm. I live in grant county wi, but also want to get laffayette co wi, iowa county wi and crawford co wi. What type of scanner works best for these. I have whistler ws 1010 now

Feb 1, 2007 · 2. I got that far, putting in the frequency and changing the mode to CT, but I don't know how to then put in the PL tone number of 91.5 in this example. I've posted in the general/specific forums before, and they referred me to post in the Michigan forum because that's where I am located.

Jul 2, 2015 · FMN usually refers to 12.5KHz bandwidth frequency modulation. Not a huge deal if it isn't set up right, you'll still hear something. Listening with a wide band FM receiver to a narrow band signal will result in low audio.

Nov 2, 2022 · The FM vs FMN video is part of a series I'm calling "Two Minute Tech Tips", which is exactly what it sounds like. So even though I have 2x the amount of time to explain things than I said prior, a lot of the info still remained edited out. What have I learned so far? That 1 or 2 minutes is not enough time to *fully* talk about a topic.
