- 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 ...

At the top of the window is the Callsign edit box. That’s where you would store
a callsign or a name of the station whose frequency you are storing. The next
line contains a Description where you can type your comments regarding the
station. Below is the Frequency you are storing and the demodulator
Bandwidth.
The mode buttons (AM, AMS, LSB, etc.) make it possible to store the
demodulation mode. If you do not wish to store a particular demodulation
mode with a frequency, simply leave the Mode button disengaged – in such
case, the frequency will be recalled with the currently selected demodulation
mode unchanged.
The squelch settings can be also stored optionally. If enabled using the
Squelch button, the specified squelch settings will be applied automatically
when the frequency is recalled, otherwise the current receiver settings will be
preserved. Note that while the Level squelch can be applied at all times, the
Noise, Voice, CTCSS and DCS squelch buttons are mutually exclusive.
