Digital Search Information:
The new Digital Frequency Search tool increases search flexibility and introduces different methods of presenting the frequency data.
Search settings:
- County (required): Enter a single county, parish, borough, etc. into this search box. For examples of accepted values, reference the “Counties” page. If you leave this field blank, the search results will return all frequencies authorized for “statewide” operation in whichever state you specify in the next box. Please Note: Statewide operation does not mean every frequency in the state; it refers to licenses that have a statewide area of operation.
- State (required): Enter a single state into the search box (two letter abbreviation). If you leave both the “County” and “State” fields blank, the search results will return all frequencies authorized for “nationwide” operation. Please Note: Nationwide operation does not mean every frequency in the county; it refers to licensees that are granted a nation-wide area of operation.
- Entity (optional): Enter all or part of an entity name (e.g., the name of a corporation, government agency, municipality, etc.) to narrow your search results. You may also use this to narrow to certain entity types by typing “city of,” for instance, which would likely return frequencies for city governments.
- City (optional): Limit your search to frequencies in a specific city. This can be particularly useful in larger counties. Please Note: Searching by county and state searches will show all licensed frequencies. If you limit your search by city, even if you search every city in a county, you will likely miss some frequencies.
- Power (optional): This field allows you to specify a minimum power output. Only frequencies authorized to transmit above the value you specify will be returned.
You are more likely to receive broadcasts that have a higher transmit power. By filtering out low power frequencies, you will increase your likelihood of receiving broadcasts; it will also substantially reduce the number of frequencies returned, making it easier to sift through the results. Values of 0-150 watts are reasonable for this box. A setting of 10 watts will exclude most portable and low power transmitters. A setting of 50-75 watts will show higher power transmitters that you are more likely to receive. A setting of 100 watts and above will return high power systems that cover a large area.
- Frequency (optional): This allows you to limit your search to a specific frequency or frequency range. Frequencies should be entered in megahertz (MHz). To enter a single frequency, simply type it in the first box (you can leave the range box empty). To search a range of frequencies, enter the center frequency in the first box; then enter the range in the second box.
For example, to search the entire land mobile VHF high band, enter “162” in the first box and “12” in the range box, which will search from 150 MHz to 174 MHz. You can also use this function to identify a frequency you found while scanning. For instance, if you found traffic on 150.775 MHz, you might input “150.775” in the first box and “0.025” in the second box (search a range allows you to compensate for tuning errors or filter widths). This would search frequencies between 150.750 MHz and 150.800 MHz.
- Age (optional): Age allows you to limit your search to frequencies that are new or have been recently modified. Enter the number of weeks (in whole numbers, no decimal or fraction) of time in the past that you would like to search. All frequencies newer than the timeframe you specify will be shown. For example, if you enter “52”, only frequencies created or modified within the last year will be shown. If either a license effective data or a frequency first use date fall within the timeframe you specify, the frequency will be shown on the results page. Frequencies with an effective date in the future are also shown.
- Scanlist (optional): Currently, only Whistler’s EZ Scan is supported. If you specify a scanlist number, the frequencies will be imported into the scanlist you specify; otherwise, they will be imported to your default scanlist. Acceptable values are 1-200.
- Show: By selecting or deselecting these two checkboxes, you can show or hide mobile and control frequencies. Hiding mobiles helps reduce duplicate frequencies, excludes repeater input frequencies, and reduces the number of low powered frequencies that you are unlikely to receive (unless you are nearby the location). Hiding “control” frequencies excludes “FX1” fixed control stations, which are usually duplicate frequencies (please note: “control” frequencies in this instance are not the same as trunked system control channels; deselecting “control” does not hide trunked system control channel frequencies).
- Trunked: Enabling this setting produces a substantially different results page. If “Separate trunked frequencies” is enabled, frequencies that are likely to be in conventional operation are listed in a separate table at the top of the results page; likewise, frequencies that are likely to be part of a trunked system are listed in a separate table at the bottom of the results page. This view also organizes frequencies by repeater site. Certain search settings, such as show/hide mobiles and sort order do not apply to the trunked frequency listing.
Overall, there are three different ways frequencies are presented with Advanced Quick Import: With “Separate trunked frequencies” off, all frequencies are listed together (this is the most complete frequency listing). With “Separate trunked frequencies” on, there is a fairly comprehensive list of conventional frequencies and a list of trunked frequencies. Due to trunked licenses that contain conventional frequencies, some frequencies aren’t shown when this option is selected.
- Type: You can select one, two, or all digital frequency types supported by this website. You must select at least one type.
- Sort by: This changes the primary sorting of most views by either frequency first or entity name first. There is additional sorting done automatically, as described on the results page.
- Format: There are currently 5 data formats for the search results. The default, “Table,” presents the data similar to the other search tabs on this website. The other formats prepare data for Quick Import into scanner programming or software radio applications.
Additional Information:
- For detailed import instructions for each scanner programming application, click the "Show/hide import procedure instructions" button near the top of the corresponding results page.
- Many of the frequencies in this database contain multiple emission designators. These frequencies might be carrying data only or analog FM voice traffic, for instance.
- This FCC license data is from the FCC's weekly data release and was last updated on Sunday, April 21, 2024 at 9:28pm CDT. The licenses for all frequencies in the database were active as of the last update. Frequencies for non-active licenses were excluded.
- For more information about each digital format, reference the notes on the respective format’s dedicated search page on this website.
- The data is from the FCC Land Mobile - Commercial and Land Mobile - Private, Land Mobile - Broadcast, and Market databases.
- As a condition of using this website, users of this website assume all risk and will comply with all applicable laws regulating radio scanning. Every attempt is made to make this database complete and accurate; however, it is meant for educational and hobby purposes only. Please use the official FCC License Search for any critical, regulatory, or professional applications.
- Due to the imperfect and incomplete nature of radio licensing, data provided on this website is not necessarily accurate to the frequencies and systems actually in use. The data on this website is intended as a reference of the radio frequency activity in your area; however, the reality on the ground is always more reliable than a database.
