You may not be able to monitor what you want on the MSWIN system. Most of the talkgroups are P25 Phase 2. The WS1040 is capable of P25 Phase 1 only. You will be able to monitor only talkgroups with D in the Mode column. DE is fully encrypted and cannot be monitored by any scanner. De is encrypted part of the time. T (TDMA) is P25 Phase 2. If all of the sites carried all of the traffic, the system would quickly be overwhelmed and run out of frequencies available. Generally, you will hear a talkgroup on the site where a unit affiliates. You want to scan the site or sites within range in the area you wish to monitor. If you scan too many sites, you will find yourself missing your local traffic. If you click on County at the top of the site frequency list in the database, it will alphabetize the sites by county so that you can see which ones are in your area. If you click on the site name in the Name column, it will give you a map of the approximate coverage area. On a wide area network such as MSWIN, a unit in your county may affiliate with a site in an adjacent county if it has a better signal. Also, a site may consist of many towers all transmitting on the same frequencies at the same time to give better coverage over a wide area. That is known as a simulcast site. In that case, all of the same traffic is carried on all of the towers within that site. You only need to enter the red control channel and blue alternate frequencies for a site. All of the frequency information is carried on the control channel. Use P25 Auto as the system type for MSWIN. That will automatically load the band plan off of the control channel. If using a single site, Multi-Site should be set to Off. If set to Roam, you will scan only the site with the best signal. If set to Stationary, you will scan all sites whose control channel frequencies are programmed. What is your city, county, agencies you want to monitor, and what programming software, if any, are you using?
