Nova Operations Receiver Menu

Scan Menu
A scan can be initiated from the receiver view menu by pressing the F7
key. A scan is where Nova can search the spectrum to determine what
RF is present. This will aid in finding a clear operating frequencies.
After a scan the RF that is found will be represented in the graph by a
series of vertical lines extending from the baseline up, the higher line
the stronger the RF signal is.
The horizontal lines show the strength of the signal in decibels. Any
stray RF below 40dB shouldn’t have too much effect on the performance.
•
The yellow area shows the 35MHz window of the front end filter.
•
The colored vertical lines will show the frequencies that that the QRX212 modules are currently set to.
Center Frequency Set
Nova’s internal receivers have a 35MHz tracking front end filter that eliminates unwanted the stray RF which
can desensitize the receiver and result in poor performance. The center frequency is the middle frequency of
the 35MHz window.
After deciding on the 35MHz operating range the center frequency should be the middle of that range.
Therefore the best RF performance will be frequencies 17.5MHz above and 17.5MHz below the center
frequency. Please note that this is a global setting for both receiver modules meaning that that the 35MHz
window will be the same for both modules.
To adjust the center filter rotate the menu encoder knob to the desired frequency, or manually enter the
desired frequency using the numeric function keys (f1 thru F10). Please note that the center frequency must be
an even number.
QRX Program
This menu is where the QRX modules firmware are updated from. Upon entering the program menu the
current firmware that each module is running will be displayed. Pressing the STAR key will initiate the update
process. Please see the firmware update instructions at the back of this manual for further information on
updating the QRX module’s firmware.
