The SD card Standard image is supplied as part of the standard firmware download. Instructions for its use are supplied elsewhere. The SD card holds information in relation to Specific Apps or as general list of items such as frequencies follows:

• ADSB: The ADBS Folder has databases of Airlines, IACO and is where the world map is located. See separate page on how to generate the map.
• FREQMAN: This is the main area used. While on the face of it, the list of frequencies used that can be loaded when using the frequency key pad or the load button in specific Apps. While on the face of it, the alteration or creation of personal SD card tailored to the specific country or region: there are some important considerations.

  • Calls: In the call App the frequency range load can not be more than 80MHz and is made up of 32 slices of 2.4Mhz. Due to the Apps speed it is recommended to limit the size of the ranges.
  • Jammer: The Jammer App can only have a Jamming frequency range of 24MHz for either a single range or a combination of all three ranges. When setting the frequency ranges in the SD card, this should be considered.
• GPS: This file holds information on how to generate GPS-Simulation files.
• LOOKINGGLASS: This folder holds a text file that is used in the LOOKINGGLASS App and is a list of the frequency scan ranges and a description. It should be noted that this APP can have only have ranges that are a minimum of 240MHz in size.In addition the range must start form 10MHz. the nominal Minimum operational frequency of HackRF. Therefore you need to consider this in planning the frequency range listed. For example you could not have a range for VHF amature band , You can only have a range from 10-250 MHz. These are very wide ranges in keeping with the Ap concept of Wide Scan of the spectrum.
