Scanner

The scanner should be able to scan about 20 frequencies per second, as it requires about 50ms to stabilize after re-tuning.

The scanner will stop into any frequency carrying a signal strong enough. You can adjust the signal power threshold with the SQUELCH.

For better scanning precision, once a frequency with a powerful enough signal is found, the scanner will analyze it for some extra milliseconds, in order to confirm that the signal is still present (and not a spurious peak).

Big Numbers Frequency

The big numbers display will show the frequency value currently being scanned, using the following color code criteria:

• GREY scanning
• YELLOW analyzing possible signal
• GREEN found a strong enough signal

Frequencies to scan

The application parses FREQMAN\SCANNER.TXT by default. You can use the Frequency manager app (Tools -> Freq managern) to add more entries to that list.

Alternatively, you are able to manually input a scanning range "on the fly" by keying in START and END frequencies, while adjusting the STEP selector.

Modulation Mode

You can select between AM (DSB / USB / LSB), NFM and WFM modulation modes.

Bottom Buttons

There are six buttons at the bottom of the screen, useful for the following tasks:

• Manually Pause / Resume the scanning
• Change scanning direction
• Jump into the MIC TX RX app (2-WAY Radio)
• Jump into the RX->AUDIO app (for further analysis)
• Delete the current frequency on display from the (temporary) scanning memory
• Add the current frequency into the SCANNER.TXT file
