Help with trunk freqs

[kb9hgi]

Can someone tell me what kind of trunking system this is? I been trying to program and listen to this on my pro-2051 and no luck. I work for the hospital and the radio communications is suppose to be on this trunk system. Here is the link

Educated guess. Motorola Type II. Without a list of talkgroup ID's, I can't tell you whether it's analog or digital. If your ID's are numbered under 30000, it will be analog. 30000 and up indicate digital.

Is this site 606 the system?

Not true, I've seen a digital system where all the TG's are less than 1000. Usually on an analog system the TG's are a multiple of 16 and on a digital system they can be in increments of 1.

Was that on a Motorola Type II system? Everything i have read states the "30000" method of identifying the type of ID code.

No it's not. I checked against his link. The freqs on your link are 900mhz, his are 800mhz.

3600 digital mixed (digital voice frequency) uses TG's with 16 bit spacing similar to analog only systems. This Chesapeake Virginia Smartzone is an example in my area. This 9600 P25 (digital CC) three Virginia counties APCO-25 Common Air Interface Exclusive system is an example of TG's from 1 to 65xxx. BTW, the newly developing Virginia STARS Statewide system is an example of the latter, except in VHF trunking.

It's on a project 25 system which is all digital with a 9600 control channel, On a digital only system TG'are 1 to 65000, on an analog or mixed mode system TG's are in increments of 16 or 32.

I'm in Quincy, IL Adams County here is the info of what I'm trying to trunk track.

SMR, 806-821/851-866 MHz, Trunked License - WNMI958 - QUINCY 2 WAY COMMUNICATIONS

000856.03750000 1 1 1 FB2 1 60.000 240.000

what kind of trunking is this? I'm trying to set up my Pro 2051 to listen to these.
I was trying Motorola Type II but no luck but I could be doing something wrong. I'm new at this trunking. Any help appreciated.

So my pro 2051 will not receive these???

The license indicates that it is analog FM voice, so your Pro-2051 should be able to track the system *if* you are within range of it. Listen to the frequencies individually and note what you hear. If you can hear noisy data, compare it to:

EDACS Control Channel: http://www.kb9ukd.com/digital/edacs96.wav

Motorola Control Channel: http://www.kb9ukd.com/digital/motorola_net.wav

If it is an LTR system, you will hear what sounds like someone keying up for about .25 second every so often.

Also, check out the RR Wiki page on trunking at:

http://wiki.radioreference.com/index.php/Trunking

It will help you get a start on understanding trunking. Good luck!

The system can be changed to have blocks of radio IDs and talk groups be digital or analog. This is defined by the codeplug burned into the EEPROM of the central controller.

How can you tell what kind of trunking system it is by the callsign? So far i have no luck with these freqs.

You can't tell the manufacturer of the system based on the FCC data. You may want to take a look at the location of the sites on the FCC license and make sure that you're reasonably close (within 20 or so miles) to it/them to ensure that you should be receiving the system reliably. If not, you may want to take the radio mobile closer to the site/sites to make a closer evaluation of the system.

The callsing will not tell you did you READ the post you quoted. Listen for a Control channel and compare it. THE FCC DOES NOT CARE WHAT EQUIPMENT THEY ARE USING. It only assignes frequencies for their system.

 

[kb9hgi]

Well I have listen to the freqs and there is no noise. But when not in trunking mode sounds like someone keys the mic every 15 seconds on the lower freq. So I tried LTR and it does nothing there just scans. Yes I live close maybe a mile if that. The hospital uses these freqs and thats where I work. Security, Grounds, Maint etc are on this trunk system thru this place. I guess my Pro 2051 will not receive them.

I just got a new pro 2096. I have the cable needed to upload or download the freq. I want. Ihave a few questions: do you all use the v-scanner when you scan or just the freq. that you put in? can you use the v-scanner plus the freq you put in? I got the freq. that I want to put in but I don't know if I should clear the v-scanner and use my list freq. or if I can keep the freq. in the v-scanner plus my freq.
thanks

The scanner doesnot scan the vscanner memory only banks 0 through 9, The vscanner memory is extra systems that can be easily loaded into scanning memory with keystrokes insted of programing with a computer. One use of vscanner memory is traveling. you can set up the vscanner memory for different areas and when you leave one area you can easily change the scanner to the new area.

It may be an LTR system, seeing as you don't hear a control channel on any of the frequencies. Do you ever hear any voice traffic on any of the frequencies in conventional mode? If not, then you may be too far away from the system to hear it. Try programming it as an LTR system and see if you ever hear anything.
