DUAL Indicator
This indicator glows Green when Dual Receive is en-
gaged.
HI SWR Indicator
This indicator glows Red if the directional coupler
and microprocessor detect an abnormally high SWR
condition (over 3.0:1) that cannot be resolved by the
Automatic Antenna Tuner.
Note
If this indicator lights up, check to be sure that you
have the correct antenna selected on the current oper-
ating band. If so, you will need to check the condition
of the antenna, its coaxial cable, and/or the connec-
tors on the cable so as to locate and correct the fault.
S-Meter (Main Receiver)
There are five functions on the main multi-meter. The
bottom five selections in the list below are transmit
functions, determined by the position of the METER
switch (# , described previously):
S: Indicates the received signal strength on
the main band (VFO-A), from S-0 to S9
+60 dB.
PO: Indicates the RF Power Output, from 0 to
250 Watts on transmit.
Indicates the compression level of the
COMP:
speech processor, from 0 to 20 dB.
Indicates the final amplifier drain current
IC:
(ID), from 0 to 15 A.
Indicates the antenna system observed
SWR:
standing wave ratio (SWR), from 1.0 to
5.0.
MIC LVL: Indicates the relative level of modulation
from the microphone amplifier stage (af-
fected by the setting of the MIC knob).

S-Meter (Sub Receiver)
On receive, this meter displays signal strength of in-
coming signals as received on the Sub (VFO-B) band
receiver.
On transmit, this meter serves as the ALC meter. The
function of this meter, on transmit, can be changed to
indication or PA Voltage (VDD) via Menu item "DIS-
PLAY 019 RIGHT TX METER."
ALC: Display of relative ALC voltage. On SSB, the
ALC level is chiefly controlled via the MIC
Gain control, #15 (described previously).
VDD: Final amplifier FET Drain Voltage (nominal
value: 50 V).
Frequency Display (See Page 37)
The upper large display field indicates the current op-
erating frequency on the main band (VFO-A), and its
TX/RX status.
The lower small display field indicates the current op-
erating frequency on the sub band (VFO-B), and its
TX/RX status.
