This function can be accessed via the scanner pulldown (figure 1), the rightmost scanner symbol on the toolbar, or Shift-F1 from the keyboard.
You can now start virtual control from the command line. Enter freescan.exe /? for more information NEW .9K

To use Freescan's various scanner interfaces;

  1. Select 'Control Scanner' from the scanner pulldown or hit shift-F1 (Figure 1)
  2. The Virtual Control setup panel appears (figure 2). Check to see if the COM settings are correct; if not, click on 'Com Port Setup' and make the necessary adjustments. Please see the Making the connection article for more information. You can hide the main program while in virtual mode by clicking the option
  3. If you find your system resources being strained, try clicking on the 'Conserve CPU' option
  4. Select which interface you would like to use, and decide on whether you wish to log all your hits. Figures 3, 4 and 5 show examples of the various interfaces


On the IPod(c) interface, the double right arrow and bar causes the scanner to scan upwards through the systems. The double left arrow and bar causes the scanner to scan downwards. 'Menu' acts the same way as if you hit the menu key on the physical scanner. The pause arrow is your hold button, the play arrow is the scan button. When you hit scan while you are already scanning, it will switch in between ID Search and ID Scan.

On the LCARS interface, if logging is not enabled, the Signal Analysis graphics will not appear.

The Tools Pulldown


  • Enable Logging Turns on the logging function but keeps it hidden. If you have a laptop with a small monitor this may be useful. Otherwise to view the log as it's being built, hit the Open Log Window selection
  • Font Changes the font and colors, dependent on what is available on the PC (figure 1)
  • Jump to Frequency Immediately tune to a given frequency. A semi-VFO like mode
  • Negative Delay (figure 2) This function pauses on a transmission then resumes scanning, regardless of whether other traffic was on that frequency.
  • Show/Hide Main Window Allows the user to show or hide the main program window usually appearing in the background.

The Jump Pulldown

This ability became available in version 2 firmware and later. It allows you to quickly move to different functions without having to use a klunky key combination. Some functions require the user to enter data (codes or frequencies) to initialize the function - see the referenced article for more information. This function is only available for the 396, 396XT, 346, BCT15 and BCD996.

  • Scan Mode Resume Scanning after ending a jumped session
  • Service Scan (figure 1) Searches a number of different services, selected as shown. Note that not all services are available for all scanners; see the Service Search article for more on this topic
  • Custom Search Enables customized searches. See the Custom Search article for more on this topic
  • Close Call Only See the Close Call article for more on this topic
  • Weather (figure 2) See the Wx Alert article for more on this topic
    • Normal Search Searches the 162 Mhz weather frequencies
    • Alert Only Activates when it detects a 1050Hz weather alert tone
    • SAME 1 through SAME 5 Activates when it receives a weather alert signal that includes any FIPS code you have programmed into the specified SAME group.
    • FIPS Search Activates when it receives a weather alert tone on any weather channel, regardless of whether a FIPS code has been programmed
  • Fire Tone Out See the Fire Tone Out article for more on this topic


Audio Recording NEW .9K

  • Files are recorded in MP3 format
  • During installation, the Lame library that gets used to encode the MP3s along with NAudio is installed via the MSI file
  • For Windows issues, please see the Connecting Radios to Soundcards article
  • For audio issues such as popping, thumping and so on, please see the DMA FAQ
  • To enable recording;
  1. In the Systems screen, look for the Tape Out area. See the Freescan Create Systems page for image examples. The following settings apply;
    1. Marked - only those talkgroups (trunk system) or frequencies (conventional) with a check mark in the Rec Out box in the associated group will be recorded.
    2. All - All talkgroups (trunk system) or frequencies (conventional) in the associated group will be recorded, regardless if the Rec Out box has been checked or not.
  2. If you selected Marked for the system that houses these group(s), make sure you click on the Rec Out box, which is only visible in the expanded view (the simple view box is not checked). See the Freescan Create Group screen for image examples

Logging Functions

  • Linear Displays each hit, one at a time (Figure 1)
    • The UID if available is now also logged in the linear log NEW .9K
  • Review Displays a hit and how many times it was encountered. (Figure 2)
    • In the review tab, RSSI is now a calculated average value of all the hits NEW .9K
  • Figure 3 shows the form FreeScan uses for capturing RID/UIDs (396XT/996XT with the proper firmware only). It also provides a remarks field so you can jot down quick notes on new finds.
  • Log data is now retained even after you close the log window and reopen it NEW .9K
