These apps represent capabilities and features we recommend for others to have available and installed on their WBT. The apps in this group run on the latest WBT software version, and demonstrate the potential of the WBT App Space. Further, they were selected because they also provide useful capabilities that expand upon the base product offering. For ALL WBT Apps with categories or PC Apps select those items from the menu.
Sort By:
TripWire App

Advanced recording tool which provides RF level triggering for QRC's Wide Band Transcorder. Features include triggering levels relative to noise floor or on absolute power levels, Exclusion Ranges, and Ability to Sweep Frequency ranges looking for signals then triggering recording when discovered.
WBT Carver
WBT Carver

This application allows you to select a sub-set of either / both frequency and time in a source QVRT file. It can then re-sample the IQ data and select from the correct time/freq ranges and save the data into a new QVRT file This application can be run directly on the WBT, or it can be run on a generic Ubuntu desktop install on a laptop / desktop computer.


This app allows continuous record capability. User will always have (at minimum) the last hour of RF recorded data.

Action Scheduler
Action Scheduler

Create and reuse lists of WBT transmit and record actions. Actions in the list of items may be sequential record, transmit or idle time steps or actions may execute at specific times of day. A list of actions may be repeated by ‘looping’.
RF Spectrum Analyzer App
Spectrum Analyzer

Feature rich spectrum analyzer which runs real time on QRC's Wide Band Transcorder (WBT). This app allows

users to set markers, look for peaks, show persistence and averaging. It has a waterfall view. It can adjust the RBW. It can perform sweeps. It can save and load custom user-defined settings. It will run on real time data as well as recorded files for post analysis.

Note, it is not recommended to use RBW less than 3 kHz when 80 MHz bandwidth is selected.

WBT Scripting App
WBT Integrated Script Editor (WISE)

A scripting tool for the Wide Band Transcorder (WBT). The WBT Integrated Script Editor (WISE) is an application to create and run LUA scripts that can use the WBT's powerful API via linked bindings to automate certain WBT tasks. Features currently implemented include setting the tuner, recording and playing of files, and user specified sleeping. QRC will continue to add to this scripting ability based on user's request via our forum at: http://forum.qrctech.com/forum/18-wide-band-transcorder/,

GPS Display App
GPS Display

Provides a basic text display of the WBT's current GPS location. Along with this, the NMEA messages, # of satellites, HDOP, RMC date, UTC time, and GPS fix Quality.
WBT Spectrum Sweep to CSV File App
Spectrum Sweeper

Fast sweep for a range of frequencies with specified resolution bandwidth and dwell time, to a .csv file for analysis. USB drive selection does not work in this version. Very useful for modeling and study of spectral data. The WBT App Sweep to File Viewer can visualize files created with this app on the WBT's display if desired.

Standard Commands for Programmable Instruments (SCPI)

The Standard Commands for Programmable Instruments (SCPI) feature of the WBT enables a user to control WBT actions through a limited set of commands via the network interface. Access the SCPI feature directly via any TCP client software, including PuTTy and the Unix ‘nc’ command.

This list using the default sort is ordered from most to least recommended.

There are other apps on the website, which are provided to show proof of concept or potential. Many of the apps in this category are admittedly still at 'proof of concept' level more than products, and we recommend using the App Color Code Legend to guide your expectations. However, every app in this category was selected because it provides a useful function to a user who is attempting to solve a specific problem or gather data in a specific way.

QRC encourages users to provide feedback on apps using our forum.
