• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

I'm a newbee to scanning trunked systems and I've been having a rough time finding frequencies to enter for the trunked system in my area. Here is what I've got: A Whistler WS1040 scanner with ARC500 software. I know the trunk system is starcomm21 and I have the Norrdge, Harwood Heights and Schiller park talk groups but what gives me trouble is finding the frequencies for the trunk system. When I look up Norridge on RadioReference.com it show the starcomm21, the talk group and it says that its patched to 471.2875 which is the old analogue frequency. I've searched high and low and I can't find the right frequencies. I found a list of 365 frequencies used by Starcomm21 in illinois but the software only has room for 32. Please someone help me get this set up properly.

Since you indicate that you already have located the talkgroup IDs used in your area. it sounds like you are having trouble determining which sites to use. Remember that you choosing the sites that cover your area, not trying to separately program some of the frequencies.

Pull up the Starcom21 database page
https://www.radioreference.com/apps/db/?sid=2324

Now, look at the list of sites:

(Only showing the first few for clarity)

From this point, there are two ways to proceed. Use either one, or look at both.

If you click on the column heading County, just above the list of sites, it will re-sort them by the county name where each site is located. Some counties have more than one site. What you are looking for is the sites that are located in your county, and depending on what you want to hear, maybe one or more of the adjacent counties. In general, a given site will carry the talkgroups for agencies in that area, whether at the county level, or cities, towns, or services (such as EMS) in the area.

Look at this section of the sites. I have clicked on the County header (highlighted) and the page has sorted the sites by their county locations:

Some of the sites are named after the city, or county they're in, others may be named after a local landmark or other things. Rather than trying to guess what the site name means, use the county sort to find the names of the sites near you, so that you can select the correct ones when importing into Win500.

You can also look at the locations on a map. Click on the title RR Locations; see the highlighted screenshot below:
1555474176671.png

When you click that, it will take you to a map showing markers where each site is. Remember that the marker is in the location based on what it's trying to cover. The actual site maybe vary some, and also some sites are simulcast, so there is more than one actual tower tied to that site listing. Here's what you get:

Use the large plus and minus signs in the lower right corner to zoom into your area. Click on the map after you have zoomed in some, then hold down the mouse key so that you can drag the map as needed to get to your area.

On the map below, I have zoomed into the Chicago metro area. Click on one of the balloon markers to find the name of the site it represents. I noticed that in some counties, there are two or more sites, where one of them is labeled as a "site on wheels". That's actually a portable site, that can be deployed to bolster coverage in an area in case of a large disaster response, or to temporarily replace a site that have been damaged or destroyed by weather or another incident.

See if the above helps you determine which sites you need for your area.

I listen to them all the time. Starcom21 site no. 149 and MCD dispatch (Municipal Consolidated Dispatch) talkgroups listed under Cook County on that Starcom21 page https://www.radioreference.com/apps/db/?sid=2324
You add the control channel and alternate frequencies for site 149 only and those talkgroups you want.
*851.5375 851.7875 851.8375
* is the Control channel and others are alternates.

Thanks Heigtx I had no idea how to use the database so efficiently. I learned quite a bit from your answer that will help me in the future.
Thank you Johnnydollar2 for the frequencies. I haven't had a chance to put them in yet but they were what I was having trouble finding,
Again thank you both for helping a newb get started.
