Specifications

Red=S9+60dB) ; it is possible to toggle at any time from FS to TFS using the TFS button
.
Please note that the TFS mode takes a while to draw all the screen. This time depends on the
accuracy (1 to 8).
Scanning
During the scanning, the signal threshold from where the scan pauses is adjustable with the
vertical slider. The pause delay (or Scanning delay) is adjustable from the
Preferences/Transceiver dialog box.
Scanning Step is set automatically in Auto mode or by the user in Manual mode. Manual mode
is recommended for FM or AM channels while Auto mode is preferable for SSB and CW.
Tip
For a better precision of the display, please set the AGC switch on AUTO position or on FAST.
Zoom
To zoom a particular portion of the spectrum : hold the mouse button (more than 1s) and
move the mouse until the upper limit is reached.
Band Scope and Monitoring
When used together, Band Scope and Monitoring are interfaced : any frequency change from
Monitoring (or directly from your transceiver) influences the spectrum display ; so you don't
need to scan again. Markers for current frequency and last frequency are displayed.
You may also use the band scope in conjunction with the Monitoring's scanning (but without
pause on busy channels): please see also how to change some parameters of the scanning.
The scanning algorithm
Scanning is done by Steps, not continously, and Step size is defined by the Accuracy
function and/or the filter width. If Step is greater than filter's width, stations may be missed.
In order to minimize this situation, TRX-Manager adds a random value at the beginning of each
scan. Thus, more stations will be detected over a repeated scan. The TFS mode provides a
graphic display of all stations detected over a long period of time.
In Auto mode scan is done in CW in order to select the narrower filter(s) and a fast AGC. You
may choose Manual scan to bypass these parameters.
