Heathkit HW-101 User Manual

NOTE: To make sure it is heard on each band, a high
content of harmonic energy is needed in the 100 kHz
calibrate signal. Because of this, some spurious signals may
also appear when tuning across some segments of the bands.
The desired 100 kHz calibrate signals are easily identified by
their greater signal strength. Also, the proper harmonics may
be peaked by the DRIVER PRESELECTOR.

NOTE: The instructions in this section use the 0 mark. on
the MAIN TUNING dial as the dial calibration point. The
same instructions also apply at any 100 kHz marking.
f
Vv Set the BAND switch at 3.5 and the MAIN TUNING
dial at O kHz. Zero beat the crystal calibrator signal at
3.5 MHz, if the 0 mark on the dial is not behind the
index line in the dial window, proceed with the
following steps.
(¥) Set the MODE switch to LSB. Be careful not to touch
the MAIN TUNING dial. Note that the calibrator
signal may or may not be exactly at zero beat in the
LSB position.
(/) Turn the SHIFT ADJUST on the VFO for an exact
_ Zero beat in the LSB mode. See Figure 1-2 (fold-out
{ from Page 100).
Recheck the zero beat in the USB mode to be certain
of the adjustment. Repeat the procedure, if necessary.
and turn the dial knob in the opposite direction to
bring the calibrate signal into zero beat at the O mark
, on the dial. Release the ZERO SET button.

This completes the alignment of your Transceiver.
NOTE: To verify that the VFO is operating on the proper
frequency, tune in a signal of known frequency, such as time
station CHU on 7335 kHz. This station is operated by the
Dominion Observatory, Canada.
