11.0 BARGRAPH DISPLAY
11.1 POWER / S-METER
In receive the bargraph shows relative signal strength in S units. In
transmit the output power is also displayed. Hold the “REV” but-
ton while transmitting and the reflected power will be displayed.
The display returns to forward power indication when the “REV”
button is released. Remember, that when operating SSB voice
transmission the displayed peak reading on the bargraph will be
substantially lower than the actual peak output power being trans-
mitted and does not indicate a transmitter fault.
S-METER LEVEL DEFINITIONS

NOTE 1: The above S-Meter levels are approximate, and accurate
calibration is not supported.
NOTE 2: The power levels in transmit are approximate, and accurate
calibration is not supported. The bargraph will also work in the Iambic
key mode.
