4.2.11 RSSI (Received Signal Strength Indication)
This screen displays the received signal strength in dBm. The reading is typically accurate
within +/- 2 dBm between -120 and -80dBm, if the radio has been correctly calibrated. For
example, -90dBm is a strong signal and –120dBm is no signal.
The screen also shows the Bit Error Rate (BER) on digital channels. RSSI and BER are
typically used to indicate signal quality.
From the Settings Sub Menu, step through the menu options with the
and
keys until the
RSSI
” menu is displayed.
Press the “
OK”
key for the “
RSSI
“ screen
If a Digital channel is selected BER will be displayed.
The RSSI/BER will be displayed until either the “
Menu
” key is pressed to return to the next
highest menu level or the “
OK
” key is pressed which will return to the main channel menu.
A lower RSSI value indicates a stronger signal, ie. –80dBm is a stronger signal than
–100dBm.
