3.
Apply an unmodulated 7. OOMc signal to the ANTE NNA connector on the rear apron.
This signal should be quite weak (approximately lOOuV), which may require very loose coupling between
the signal generator or oscillator to the transceiver.
it to PTT.
4.
Set the FUNCTION switch at STANDBY, and af ter one or two minutes of warmup, turn
5.
Turn the RF GAIN control to the fully cw position, and then turn up the AF GAIN control
until normal receiver noise is heard.
6.
With the MAIN TUNING control set to 7. OOMc, adjust the slug of VFO coil L4 until zero
beat is heard in the loudspeaker. The S-Meter reading may be peaked with the EXCITE R TUNE con-
trol and with the PA TUNE control.
If
it is not possible to peak the signal with the EXCITER TUNE
control, set this control to mid-rotation and adjust the slug of coil L
ll
to peak the meter reading.
The R F GAIN control should be adjusted to yield an S-9 reading.
7.
Apply a 7. 30Mc input signal to the ANTENNA terminal, as per the procedure in step (3).
8.
Turn the MAIN TUNING control toward the high end of the 40 meter band until the applied
signal is heard.
If
it is heard at an indicated frequency that is higher than 7. 30Mc, unmesh the plates
of C40 by several degrees of rotation, and repeat steps (3) through (8).
It
will not be necessary to
make further adjustments on L
ll
at this time.
If
the signal is heard at an indicated frequency of less than 7. 30Mc, mesh the plates of
C40 by several degrees of rotation and proceed as above. This procedure is continued until the signal
is heard at exactly 7. 30Mc on the dial. Do not proceed to step (9) until this condition is achieved.
9.
Set the FUNC TION switch at STANDBY, and the BAND switch at 80 meters.
10.
Set the MAIN TUNING control at 3. 80Mc, and leave the RF GAIN and AF GAIN controls
in the positions they had upon the completion of step (6).
11.
Apply an unmodulated signal of 3. 80 Mc to the ANTENNA connector.
12.
Set the FUNCTION switch at PTT, and adjust trimmer capacitor C42 until zero-beat
is heard. The signal should be peaked on the S-Meter by setting the EXCITE R TUNE control to mid-
rotation and adjusting the slug of L lO.
13.
Replace the VFO cover and secure it with four #6 self -tapping screws. This completes
the VFO alignment. There should be a negligible change in dial readings due to the presence of the
VFO cover.
If
it is desired to correct for this change, the hairline may be reset from the front
panel.

Connect a suitable dummy antenna to the ANTENNA connector, and an output power
meter (R F ammeter, etc. ) to the connecting transmission line. Connect a microphone with a PTT
button (or an external PTT switch) to the MIC connector. Do not connect key.
