Frequency Scan

PRESS TO SCAN
The frequency scan menu is where the QRX can scan the specified frequency range and search for a clear
frequency. After a scan a graphic display of the RF that is present in that specified range will be shown. The
QRX will also suggest a clear frequency. That frequency can be accepted by pressing the INC key. Or press
the A/B key or the DEC key to skip the chosen frequency and have the QRX suggest another frequency.

Single mode scanning


Turn off the TRX transmitter.

From the frequency scan menu
press the INC key to s a scan.

While the block is being scanned, the frequency being examined is displayed in the bottom half of the
screen. Once the scan has completed, a graphic map of what was scanned is displayed. The low end of the
frequency range is on the left side and the high end is on the right. Wherever RF is found, a vertical line is
drawn. It extends from the baseline up. The length of the line indicates the level or strength of the found
RF at that frequency.

Selecting the frequency

When the scan is complete QRX
will draw a vertical blinking line
on the display to indicate where
the first suggested frequency is in the scan and displays the frequency number below the graphic.

Press the INC key to accept the new frequency.

Press the A/B key or the DEC key to suggest another frequency.

Dual mode scanning

In dual mode the two operating
frequencies must be within
35MHz of each other. When the
QRX200 is set to dual mode the
scan page will flash between these two screens. Pressing the INC key will scan the full chosen scan range
(scan range is set in the next menu) and recommend a frequency from the entire range. If a second
frequency is being chosen to work with a previous chosen frequency, press the DEC key to limit the scan to a
70MHz window - 35MHz above and 35MHz below the other selected frequency. To toggle between scanning
RXA and RXB press the A/B key.
After a scan is triggered, by either pressing INC or DEC key, the QRX will scan and suggest a frequency. After
the scan is completed that frequency can be accepted or rejected the way as in single mode.
If an exclamation point appears after the suggested frequency that is the QRX200 warning that the shown
frequency is more than 35MHz away from the other frequency. That frequency can be selected provided a
new frequency that is within 35MHz of this frequency will be selected for the other receiver.
After the first scan turn on the first transmitter and set it to the chosen frequency. This way when another
scan is performed for the second transmitter the QRX will not select the same, or adjacent, frequency.
