Memory Scanning
The last scanning method is
Memory Scanning
. Here the receiver will step
through memory frequencies, starting from the first one to the last one, and
repeating the loop until a signal is found or until manually stopped.
If a squelch value is stored with a memory, its value will be used to compare
with the current signal level. If there is no value stored, the current squelch
value will be assumed.
It is possible to restrict scanned frequencies to particular memory groups only.
These groups can be selected from the
Options | Scanning | Groups
window, accessible from the top bar menu. Groups can be enabled/disabled
using the check box
Enable group restriction
in the same window.
S-meter
The WiNRADiO G305 receiver
Signal Strength Meter
(
S-meter
) makes it
possible to measure signal strength in either
S-units
,
dBm
or
µV
(
microvolts
).
The units are selected by correspondingly marked buttons on the right side of
the display. In the microvolt mode, the
p-p
button is also enabled, making it
possible to select
peak-to-peak
values rather than the default
RMS
(
Root
Mean Square
) values.
S-meter
The S-meter also shows the currently selected value of the squelch (the red
section at the bottom side of the scale). When the signal strength falls under
the squelch level (i.e. the needle falls in the red region and turns red also), the
receiver audio will be muted and “
squelched
” will be displayed.
