Vertex Standard Co.,Ltd. 3
To perform alignment of the transceiver, it must first be placed in the “Alignment
Mode,” in which the adjustments will be made and then stored into memory.
To enter the Alignment mode, press and hold in the [REV(DW)] and [D/MR(MW)] keys
while turning the radio on. Once the radio is on, release these two key. The transceiver
is now in the “Alignment Mode.”
PLL Reference Frequency
ˆ
Rotate the DIAL knob to set the alignment parameter to “146.000 rF.”
ˆ
Press the [D/MR(MW)] key to enable adjustment of the “PLL Reference Frequency.”
ˆ
Press the PTT switch to activate the transmitter, adjust the DIAL knob so that the
counter frequency reading is 146.000 MHz (±100 Hz).
ˆ
Press the [D/MR(MW)] key.
RF Front-end Tuning
ˆ
Inject a 145.100 MHz signal at a level of –10 dBµ (with 1 kHz modulation @±3.5
kHz deviation) from the RF signal generator.
ˆ
Rotate the DIAL knob to set the alignment parameter to “145.100 tn.”
ˆ
Press the [D/MR(MW)] key to enable adjustment of the “RF Front-end Tuning.”
ˆ
Adjust the DIAL knob so that the maximum SINAD.
ˆ
Press the [D/MR(MW)] key.
Squelch Threshold Level
ˆ
Inject a 145.100 MHz signal at a level of –14 dBµ (with 1 kHz modulation @±3.5
kHz deviation) from the RF signal generator.
ˆ
Rotate the SQL knob to the 10-o’clocl position.
ˆ
Rotate the DIAL knob to set the alignment parameter to “145.100 tL.”
ˆ
Press the [D/MR(MW)] key to enable adjustment of the “Squelch Threshold Level.”
ˆ
Press the [D/MR(MW)] key three times.
ˆ
Press the [D/MR(MW)] key.
S-meter Level (S-1)
ˆ
Inject a 145.100 MHz signal at a level of –5 dBµ (with 1 kHz modulation @±3.5 kHz
deviation) from the RF signal generator.
ˆ
Rotate the DIAL knob to set the alignment parameter to “145.100 S1.”
ˆ
Press the [D/MR(MW)] key to enable adjustment of the “S-meter Level (S-1).”
