Turn the BAND switch to 14.0, the Main tuning dial to 14.2 MHz, and the DRIVER
PRESELECTOR to the 14.2 position (See Error: Reference source not found on
page 33).
Tune the Main tuning dial for the loudest signal and check for the calibrate signal.
Adjust driver grid coil 14 and driver plate coil 14 for a maximum S-Meter indication.
Set the BAND switch at 7.0, the Main tuning dial at 7.2 MHz, and the DRlVER-
PRESELECTOR to the 7.2 position.
Note: A Heathkit service bulletin HW-101-48 recommended setting the Driver-
Preselector knob to the 1 o’clock position rather than the 2 o’clock position shown to
ensure that the Driver-Preselector could be peaked at both ends of the band.
Tune the Main tuning dial for the loudest signal.
Adjust driver grid coil 7 and driver plate coil 7 for a maximum S-Meter indication.
Turn the FUNCTION switch to PTT
Proper receiver operation will be indicated by calibrator signals of S9 +20 db at 3700
kHz and decreasing to S6 at 29.2 MHz.
s.2. Transmitter Alignment
See the "Reading the Meter" section on Page (tbd) before making any more
adjustments.
NOTE: The coil cover must be in place for transmitter operation.
1. Connect a push-to-talk microphone to the MIC connector on the front panel.
If an oscilloscope is available, connect the oscilloscope between the RF OUT jack and the
dummy load. Be sure the dummy load is capable of 100 watts dissipation.
Set the NEUTRALIZING CAPACITOR (on the RF cage) at the 1/2 meshed position. The slot in
the shaft should be vertical.
Set the front panel controls as follows:
DRIVER PRESELECTOR - 12 o'clock position.
MIC/CW LEVEL - fully counter clockwise.
FINAL (round knob) - to 80.
FINAL (lever knob) - over the 50 marking.
MODE - LSB.
BAND - 3.5
Main tuning dial - 3.7 MHz.
FUNCTION - PTT.
FILTER - SSB.
