Scanning the State Patrol

[shaft]

Im using my Pro-95 and I hardly ever hear any traffic from them. I mainly hear my neighbor when he goes on duty, but thats it. Once in a blue moon I'll pick up some traffic.

I live Near I-70-and 40/61 plus driving down the highways towards STL you would think I would be able to pick up traffic but I dont. I have the surrounding Troops programmed (lowband freqs) in. Does anyone else in the STL area pick up a bunch of traffic?

 

[BaLa]

should be at least some, do you usually hear dispatch?
If not you might consider upgrading your antenna
What are you using?
If you're using the stock Pro95 antenna, it sux for Lowband VHF.


anybody know if they have started using the P25 Freqs yet?

It was late lastnight when I was thinking about it. It probably is the antenna since Im using an 800mhz one, I do have a lowband ant Ill try.

MSHP Scanner information

Hello I have never really posted on here but I am in Lincoln County Missouri right up 61 from you Shaft. Lincoln and Pike Counties are both in their Zone 5 of Troop C and I happen to know many of the state troopers that work and live in this zone. Troopers really don't know nor care to know the radio side of their communications. All they care about is that it works. LOL. But to help with your question one trooper in my zone use to be a dispatcher and he is full of information that helps us all when it comes to monitoring MSHP on the scanner up here. Ok first off they use a duplex system as you are probably aware of. Wentzville falls into the same area as me. In your scanner put in 42.140 and you will hear dispatching only. Then add 42.260 this is the car side of trasmissions going on. Now the bad thing about MSHP is that you will only hear 42.260 come alive with the car side if they are within about 25 miles of you if that. So in another words you will only hear the cars that work your zone you live in or are traveling through if your scanner is mobile. Now the million dollar question if it only goes about 25 miles how in the world does Lincoln and Pike county cars make it down to Town and Country at Troop HQ simple the 42.260 takes the cars transmission to the nearest County Relay tower which there is one in Eolia MO and Warrenton MO then it bounces to Town and Country. The relay towers have 456.??? assigned to them but good luck getting anything out of them because it goes from the tower site to Troop HQ via phone lines so us scanner people get pooped on. The traffic you hear out of those cars is what my trooper friend likes to say you are in the G spot of Trooper communications which he says means you are in the direct path line from the car to the relay tower and are taking the call along with the relay tower. Plus Troop C scanner traffic is very very very low on the car side because each HP car has a laptop to run their traffic stops on so there is no need to call dispatch. So the 42.140 side is the most talkive since it is always going BEEP attention Troop C officers special attention zone 3 and on with the call. Most of the traffic i get on 42.260 is the troopers for my zone going 10-41 and 10-42 and where they are going to meet for lunch / dinner, and when they play a game of tag sitting on opposite sides of 61 you will hear on 42.260 "Hey Scottie the black truck 77 in 65 nail his a** boy." Followed by "Gotta Red Rider."

So sorry for the long post but the only two codes you will need are 42.140 for dispatch and 42.260 for the car side which is dead and few and far transmissions between but as good as MSHP will get for our area.

Hope this is helpful to you.

Wow, thanks for the lengthy reply. That certainly makes a lot of sense why I hardly hear any traffic from them. I do have those 2 freqs programmed in, and I do hear on occassion dispatch, and very rarely some car 2 car. Like I said before I hear my neighbor(s) going on duty than anything else.

There is a state-wide UHF link via repeaters too. I forget the frequency, but you likely can find it here at the site on the state listing. It is in the 440 band.

I travel through on I-70 going both directions at least once a year. My V-Scanner for Missouri has F Mobile Rel 456.52500 CT 103.5 in all 10 banks.

Vern, are you thinking of the Show-Me Intertie amateur repeater link between St. Louis and Columbia/Jefferson City?

Boonville 442.700
High Hill 442.045
Jefferson City 443.175
St. Louis 443.475
Columbia 444.425

State HP wouldn't be operating on 440 since that would be in the amateur 70CM band.

each troop has a few crossband repeaters (mobile relays)

for St. Louis
Frequency Input License Type Tone CH Description Mode
456.17500, 456.27500, 456.57500, 456.62500

they are all relatively low power.
look at the Database.

It would be a lot more helpful if you would consider paragraphs. No offense, but
it makes things easier to read.

Now, on to the meat.

The 456.XXX frequencies are actually the link between the tower, and troop. Phone lines are rarely used in the Missouri HIPO system for linking sites. They use highly
directional antennas, and low power. If you are in that path, and monitor, the
links are great monitoring.

They used to run some 460mhz links as well (that was like 15 years ago). They have replaced those with the 456 links they have now from what I see. Mobile extenders are also used in VHF range too.

Interesting discussion. I have listened to the HP for 2 years, and now the bandplan makes more sense than ever before.
FWIW- Polk county/ Bolivar area- I listen to Dispatch on 42.06 and cars on 42.22
