I am in Daviess as well.

Is there a way to filter out the data that is sent over the KSP radio's so all I hear is the audio? I have a PRO-197.

 

[gtriever]

What data?

 

[crowe427]

What data?

I noticed that my scanner kept hanging on KSP frequency... So I turned the volume up and you can hear some sort of data sound. Not really sure what it is. Dont know if it matters but I am listening to the B frequency and I have the NAC programmed.

 

[sound_efex]

I assume...

I assume you are referring to the buzzing and humming that occurs form the radio not locking on and decoding the P-25 signal.

You need to get a stronger signal to the antenna. Try monitoring a different KSP tower. The closest tower is not always the best for your location. Adjust the length and/or orientation of the antenna relative to the radio. Shop around for a better antenna. Move your radio to a different location. Metal panels and basements are not scanner friendly. The simplest fix would be to raise an outdoor antenna.

If you're not in a hole or behind a hill relative to the KSP towers, you should hopefully find an improved signal.

The best way to monitor KSP is to load all of the freqs for the Post desired.... Load all of the freqs and then go outside and see what happens.... With KSP narrow banded the ole' UHF freqs sometimes don't make it all the way to the receiver like they used to.... remember, with digital, either you have a signal or you have noise, unlike analog.

I have a good strong signal and I hear it over KSP Post 16 Henderson South and KSP Post 2 St Charles towers. I listen to one at home and the other at work. The voice quality is really good its not garbled or anything. The data sound I hear is very low and constant. I will keep digging and see what it is. I'm thinking its scanner operator error

Your scanner is fine. The problem appears to a Post 2 issue. After the P25 signal has ended, the repeater holds the freq for an excessively long time before releasing it. I get this too on both of my digital radios with all Post 2 freqs that I have monitored. It does not happen with Post 1 freqs. The data sound you hear is internal to the scanner. The speaker is amplifying it when the volume is turned up. You will notice the same thing in while scanning or searching.

My work-around to this problem is to monitor the Post 2 input freq. When a trooper is in the area, I unlock the repeater to get both sides of the conversation. I still have Post 2 unlocked in the 2nd scanner but it not my primary radio.

Thanks for the info!

Anybody catch anything on the bridge collapse over Kentucky Lake?

Word is an off-duty undercover KSP trooper was one of the first on the scene.

Would have been plenty of traffic on Post 1, Marshall County, Trigg County and US Coast Guard at the very least.

Anyone in the Louisville Area

I am going to be traveling to Louisville in a few months and was wondering if anyone in the Louisville area could tell me if KSP has much presence in Louisville? Do they answer calls in Jefferson County, or assist the LMPD? I have a digital scanner I was wanting to take, and was wondering if I would hear KSP action in Louisville (I know I can monitor Post 4 traffic- I was just wondering if KSP does much in Louisville)? If they do, do the troopers assigned to Louisville use the same B & A channels for Post 4 or do they use the frequencies listed in the database as "Louisville-Jefferson County Transmitter"? I guess they do not use the new MetroSafe TRS do they?

Thanks for the info.

 

[pjscott51]

KSP has little presents in Louisville and do not assist LMPD. If there's a major event like the State Fair at the Kentucky Exposition Center or the Derby they will have a presents. In Louisville you should be able to monitor Post 4 E-town, Post 12 Frankfort and Post 5 Campbellsburg.

Hope this helps,

Paul

This should have been "Post 1" traffic from the night that the Eggner Ferry Bridge was hit by the Delta Mariner and collapsed. Looking at the time I made the post, not sure if I was just tired or just my normal non-ability to type.

This the audio from that night:
Kentucky State Police responding to the Eggner Ferry Bridge getting hit by the Delta Mariner Ship
KSP did a great job

If you listen to a P25 signal with an analog scanner, if you listen to one on the output of a repeater frequency, it sounds like the "data" signal you hear is some sort of idle tone the repeater sends out to keep the channel locked on for X amount of time. Sort of like the repeater tone on analog repeaters, except virtually inaudible. Just lets a radio/scanner that repeatedly scans channels keep the channel to complete a two-way conversation.

That's how I see it. Correct me if I'm wrong. KSP 14 does it as well.

I have

P25 signals are data signals.

I have a good strong signal

The voice quality is really good

I turned the volume up and you can hear some sort of data sound.

This last statement is the smoking gun. I probably mis-diagnosed the situation by assuming an internal scanner bug. Electro Magnetic Interference (from other scanners, wifi, computers, passing vehicles, florescent lights, you name it) is a more than likely culprit.

lets a radio/scanner that repeatedly scans channels keep the channel to complete a two-way conversation.

This seems unnecessary for KSP communications purposes. Scanners might be employed for other reasons, or they may be seen as a distraction to the critical mission of the KSP. For officer safety I assume that direct two way communication is preferred.

But, I have been wrong a couple of times before before.
