Center Frequency Set
The RX-12R has a 35MHz tracking front end filter that eliminates unwanted 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 set to the middle of that range.
Therefore the best performance of the RX-12R will be frequencies chosen 17.5MHz above and 17.5MHz below
the center frequency. Please note that this is a global setting for all QRX212 modules meaning that that the
35MHz window will be the same for all modules.
To adjust the center filter rotate the menu encoder knob to the desired frequency, or manually enter the
desired frequency using the numeric keypad.
