MRK960 dual true diversity receiver
In the above picture a typical graph of the scan function (only the graph area of the display). This graph, or-
dered by channel numbers, shows the RF levels in dBµV for each channel in the selected group (i.e. Ch: 00).
Rotating the knob the small arrow cursor moves from a channel to the next one; on the right of the graph it is
possible to see the rank of the channel selected by the cursor, its number, its frequency and the RF level. Press-
ing the knob the order of the graph became the rank, not the channel number. In this way it is more simple to
choose channels with lower RF noise, they are in the left part of the graph. See at the picture below:
In this graph the channels are ordered by rank. Turning the knob it is possible to change the channel and read-
ing its number, frequency and level of RF noise.
The horizontal dashed line is the squelch level set before starting the scan.
Connecting an headphone at the monitor output, is possible to ear the signal in the channel selected by the
knob. If the RF signal is below the squelch level, the upper button near the display disable/enable the squelch
so the audio output is enabled also for weak RF signal.
The SELECT button is the exit from the SCAN function tuning the receiver on the selected channel, the EXIT but-
ton exits from the SCAN function leaving the receiver channel unchanged.
