lead,
“–”
lead: GND) on the MAIN Unit.
r
Select the
“
REV ALC
”
channel (10.25000 MHz), and recall the [REV ALC] parameter on the
computer.
r
Key the transmitter (connect pin 5 of the MIC jack to GND) with no microphone input, then
press the UP/DOWN key so that the DC voltmeter reading is xx V
±
xx V.
HI SWR Indicator Alignment
r
Connect the 16
Ω
Dummy Load (or three 50
Ω
Dummy Loads in parallel) to the ANT jack.
r
Select the
“
REV ALC
”
channel (10.25000 MHz), and recall the [HI SWR] parameter on the
computer.
r
Key the transmitter (connect pin 5 of the MIC jack to GND) with no microphone input, then
press the UP/DOWN key so that the front panels LED indicator will blinks yellow.
Carrier Balance Alignment
r
With the 50 dB Attenuator (or 50
Ω
