maximum deflection on the Main S-meter.
Set the MAIN Band's Roofing Filter bandwidth
to "3 kHz."
Adjust T1021 and T1022 on the RX-1 Unit for
maximum deflection on the Main S-meter.
Set the RF Signal Generator output level to 0 dBµ
at 52.500 MHz (with ±3.5 kHz deviation @1 kHz).
Set the MAIN Band (VFO-A) frequency to 52.500
MHz in the FM mode.
Set the MAIN Band's Roofing Filter bandwidth
to "AUTO."
