Compiling some statistics

[BinaryMode]

Looking at my logs for three months I've determined Boyd Lake state park has at least 20 radios. And Loveland Fire/EMS has at least a whopping 287 radios! I did note some erroneous radio IDs totally about 20 so now I don't know if I can fully trust my radio to log RIDs exactly. But I did note all the real RIDs start with 30. I also see that at least one console is primarily responsible for all fire pages.

Some more Stats.

I primarily monitor the Bald North and Loveland towers and have complied 66 days worth of statistics based on the most used frequencies from both of these towers, and what frequencies were never used at all in those 66 days, which I thought that particular stat was really interesting.

There are of course a few minor variables in that I mostly monitor Fire/EMS, Boyd Lake and CDOT with other stuff sprinkled in between. So given this I'm not actually monitoring everything and anything coming off the towers. Nevertheless, the 66 days worth of 24/7 monitoring and recording stats should be a really good indicator as to what frequencies are the most popular and what frequencies have never been used.

In case you were wondering. I used to work for the National Security Agency as a statistician, but since retired and now make Halloween costumes for dogs. LOL! J/K

Compiling 87 days worth of Loveland fire pages on dispatch, I have calculated the following statistics of how many pages there were per hour in all those 87 days. As you can see from the attached chart, it seems at 10 AM the Loveland fire department is typically at its busiest and during the hours between 23 and 06 things are super calm. But once 7 AM rolls around all hell breaks lose so to speak. Interesting to note that is seems at 20:00 things calm down for a bit and then at 21:00 things go back up which is comparable to 12 noon's pages and then start to tapper off after 21:00.

Again, this is 87 days worth of fire dispatch pages.

If anyone is wondering just where on Earth I'm getting all this data, it's thanks to the awesome program ProScan and its created history log. I never would have thought in a billion years I'd have this much data just from a scanner. It's been super fun to compile all the data, and with P25 there's actually a lot of metadata surrounding it all.

The attached chart was calculated with PHP and chart.js using XAMPP. I actually don't know PHP or any code for that matter, but ChatGPT helped. AI (Artificial Intelligence) is one - amazing - little - animal, let me tell you. I used Notepad++ and Libre Office Calc to massage all the data for computing.

interesting data , understand that for Bald mountain and all the dtrs sites your seeing control channels only or that's how I understand it , being a trunk system the radio does the work

 

[BinaryMode]

Not sure I understand. My radios are and always have been (since circa 2004) programed with the control channels and the voice channels. I never EVER rely on control channel only programming. I program by hand and via ProScan.

Reason I do this is actually demonstrated in the above data in that with the Loveland tower the common control channel of 853.7625 was used as a voice channel three times. So that means the control channel switched to something else for a short time. Though, I don't see that also happening with the Bald tower as the current control channel of 853.6375 was never logged as having any voice on it.

Now I wanted to know what was the 12 most chatty RIDs (Radio IDs). Interesting to note that the radios for the consoles all start with 3773**. There are 8 here, but dispatch its self is it's own unique RID that does not follow the 3773** nomenclature.

Data taken from Loveland fire/EMS and county mutual aid channels. The dispatch talk group its self was omitted. So this data is for the fire ground channels.

I wanted to do the same thing as above except this time omit the console radios. RID number 304506 shown in the attachment may be erroneous, but I believe it's Engine 50, I think... The second paramedic 311 RID sounds like a handheld.

Again, these are just the chattiest. So they are no way in any form who's paged the most. That I really couldn't tell you unless I listened to each and every single dispatch for months on end and took notes. I'm sure one day AI could do it. i.e. by feeding it loads of audio and having it spit out the results. From my listening I'd have to say Squad 46 and others from Station 6 get paged the most. At least that's what it seems like. Reason is probably due to a couple factors: A) The stretch of highway from Denver Ave on East to Centerra has constant MVAs damn near everyday. Then there's the I-25 interchange right there too. Also, the Centerra shopping mall and whatnot out there has over 150 businesses and restaurants so that too plays a part.

Some more of my Stats just being bored.

Wanted to see if perhaps it was true that a full moon meant more dispatch calls. Well, in terms of the fire department. So looked at three months of full Moons over the span of three days since most people see a full moon for three days and three months of new Moons of data. So three full Moons and three new Moons respectively. After looking at the data for those periods and mean averaging the numbers there were 233 dispatch pages for full Moons and 230 dispatch pages for new Moons. So only three more pages during a full Moon. I'll continue testing this Stat more in the future with more data.

Also, looking at 87 days of data and sampling three days from each month (there was a partial month) it looks there are a mean average of 52 dispatch pages per day.


----NERD MODE AHEAD----

And now for some really off the wall nerdy Stat stuff that really means nothing at all but was just curious.

I took the times in HH:MM (hours/minutes) of each dispatch page and added the hour and minute together to form a "sum." So if the dispatch page time was at 01:25 the sum is: 26. Or if the time was 00:34 the sum would be: 34. Or 03:43 the sum would be 46. Understand?

Now I have a list of over 4,000 "sums" from 87 days worth of dispatches. The five most occurring sums were: 25, 58, 38, 41, 40. The first three sums are not prime numbers. These numbers (sums) represent a 9% distributed probability. LOL!

3,636 of these sums are not prime numbers.

1,219 are prime numbers.

Making 33.5% prime. So under half.

What does this all mean? Nothing, but thought it would be cool to calculate.
