- Of particular interest to many users will be the CPU load (excessive CPU load may cause sluggish behaviour or freezing of the computer), and Audio latency. Apart from DDC bandwidth, CPU load may be minimized by reducing the Demodulator filter length (...
- Note: When measuring sensitivity using SINAD, it is very important that the Audio Filter is enabled and the cut-off frequencies (and for FM measurements, also the de-emphasis) are set according to the specified test conditions. Proper audio filtering ...

User memory files are of a special format with the extension “.r7m”. Scheduler
files have the extension “.r7s”. Sweeper data (refer to the Sweeper chapter)
have the extension “.g39ddcswp”.
Spectra are all saved as images, using the standard BMP format.
Memory Export and Import
The Save user memory as and Load user memory functions can save or
load the user memory in the CSV format (comma separated values), making it
possible to export frequencies in this commonly used format, as well as import
frequencies from third party sources.
Each line of CSV file contains the following information, in this particular order:
“Folder”, “Callsign”, “Description”, “Frequency”, “Mode”, “Bandwidth”, “Level
squelch”, “Noise squelch”, “Voice squelch”, “CTCSS squelch “, ”DCS squelch”,
“Audio filter low”, “Audio filter high”, “Audio filter de-emphasis”
