“Frequency search” tab with a database and search parameters setting.
To run the automatic frequency search the following parameters should be set:
 “From” and “to”: define the search range of a certain frequency band.
 Step: defines the unit size each time when the system jumps to the next frequency.
 Interval: defines how long should the frequency search mode stay at one frequency before it
jumps to the next frequency. Note that the Interval should not be very short, so that the classifier
in frequency search mode can catch the signal in the bandwidth. A reasonable value can be 15
seconds.
 Search strategy: defines how does a classifier or classifier code check work when it catches a sig-
nal. The possible strategies are Classify (P1), Classify – Tablecheck (P2), Classify – Tablecheck –
Codecheck (P3), Classify – Tablecheck – Decoding (P4) and Classify – Tablecheck – Codecheck –
Decoding (P5).
When a classifier or a classifier code check delivers results, parameters will appear in their corre-
sponding database fields and the whole result will appear in the “Remarks” field.
 Loop: is a checkbox. It defines whether the frequency search should begin from the first frequency
(From) when it reaches the last frequency (to).
 Use squelch: is a checkbox. When it is selected (checked), the system will deliver a result when
the signal is above the squelch level.
 Automatic insert: is a checkbox. It defines when the frequency search delivers a result (signal
above the squelch level or some classifier code check results) whether it will be inserted into the
database. The new database entry appears in the “Frequency search” tab.
At the last line of the GUI there are four buttons with the following functions:
 Start button: starts the frequency search from the first frequency defined in “From” field and jump
to the next frequency (+ Step) after an Interval period.
 Stop button: stops the frequency search function.
