Band Scope mode
Band Scope mode is a special type of Search mode where the scanner displays the strength of any signal it finds.- In a band scope search, the scanner starts at the lowest frequency in the range and moves up the search range.
- In Max Hold Search mode, the scanner displays the strongest signal that it found.
- If you manually set the mode to NFM or FM, the scanner will not reliably detect signals that are modulated in either FMB or WFM.
To turn on Band Scope mode:
Band Scope mode is the default setting for Search Key 3. To turn on Band Scope mode, enter Search mode, then tap FUNCTION + 3 (SR3) . (To change the Search Key assignment, see Search Keys#Programming Search Keys.)Reading the display in Band Scope mode
Changing Band Scope Parameters
To change between band scope search and band search max hold modes, press F+SCAN. You can adjust the span, center frequency, and step size used in Band Scope mode. To make an adjustment, press ./no one time. The setting being adjusted flashes. Repeatedly press ./no until the setting you want to adjust is flashing.- CF -- Center Frequency. While CF is flashing, press E/yes then enter the desired center frequency.
-
SPN -- Span. While SPN is flashing, rotate the scroll knob to select the desired frequency span. You can select from:
- 0.2MHz, 0.4MHz, 0.6MHz, 0.8MHz, 1MHz, 2MHz, 4MHz, 6MHz, 8MHz, 10MHz, 20MHz, 40MHz, 60MHz, 80MHz, 100MHz, 120MHz, 140MHz, 160MHz, 180MHz, 200MHz, 250MHz, 300MHz, 350MHz, 400MHz, 450MHz, and 500MHz
-
STP -- Step. While STP is flashing, rotate the scroll knob to select the desired frequency step. You can select from:
- 5kHz, 6.25kHz, 7.5kHz, 8.33kHz, 10kHz, 12.5kHz, 15kHz, 20kHz, 25kHz, 50kHz, and 100kHz.
