UNIT ADJ.SPOT
MAIN TC101 Adjust so that Tx Frequency
becomes within 145.90MHz±100Hz
MAIN L123 Adjust so that PD voltage becomes
1.5V
MAIN Confirm if PD voltage becomes less
than 7.3 V
MAIN L105, L104 Repeatedly adjust so that the Rx
L103, L102 sensitivity becomes in maximum.
Confirm:
At -7dBu SINAD more than 12dB
