144MHz band Alignment
○ Squelch Hysteresis Adjust (HIS)
Rotate the DIAL for minimum squelch hysteresis, then press the [V/M] button.
Rotate the DIAL to select the next setting.
○ Squelch Preset Threshold (tHL)
Inject a -15dBµ RF signal (1 kHz tone @ ±3.5kHz deviation), then press the [V/M]
button. Rotate the DIAL to select the next setting.
○ Squelch Preset Tight (tIg)
Adjust the generator level for a -4dBµ signal, then press the [V/M] button. Rotate
the DIAL to select the next setting.
○ Low-Scale S-1 Adjustment (S1)
Adjust the generator level to -7dBµ (1 kHz tone @ ±3.5kHz deviation), then press
the [V/M] button. Rotate the DIAL to select the next setting.
○ S-Meter Full-Scale Adjust (S9)
Adjust the generator level to +20dBµ (1 kHz tone @ ±3.5kHz deviation), then press
the [V/M] button. Rotate the DIAL to select the next setting.
○ Wide Low-Scale S-1 Adjustment (S1)
Adjust the generator level to 0dBµ (1 kHz tone @ ±20kHz deviation), then press
the [V/M] button. Rotate the DIAL to select the next setting.
○ Wide S-Meter Full-Scale Adjust (S9)
Adjust the generator level to +20dBµ (1 kHz tone @ ±20kHz deviation), then press
the [V/M] button. Rotate the DIAL to select the next setting.
○ High TX Power Adjust (HPo)
Transmit and adjust the output power level for 3W ±0.3W by rotating DIAL, then
press the [V/M] button. Rotate the DIAL to select the next setting.
○ Low TX Power Adjust (LPo)
Transmit and adjust the output power level for 50mW ±30mW by rotating DIAL,
then press the [V/M] button. Rotate the DIAL to select the next setting.
○ TX Deviation Adjustment (dEV)
Transmit and adjust the deviation for 4.2KHz ±0.2KHz by rotating DIAL, then
press the [V/M] button. Rotate the DIAL to select the next setting.
This completes the UHF band internal alignment routine, to save all settings and
exit, press [BAND] button.
