CAUTION: The Transceiver should be retuned if the
frequency is changed by any great amount. Be sure to
readjust the FINAL TUNE controls. It may also be
necessary to repeak the DRIVER PRESELECTOR control.
This completes the Initial Tune Up. Before placing the
Transceiver in operation, complete either the following CW
or Single Sideband adjustments.
For CW operation, the FUNCTION switch can be set to
either the PTT or VOX positions. Even though CW
operation is possible in the Calibrate position, it is not
recommended because of possible spurious outputs from
calibrator signals being present at the grid of the driver stage.
For 400 Hz CW selectivity, the Heath SBA-301-2 CW crystal

DELAY control so the relays stay energized between
groups of characters. Ciockwise rotation of this
control will increase the holding time of the relays.
The final setting of the VOX DELAY control will be
determined by the sending speed of the operator. The
slower the sending speed, the higher the setting of this
control. NOTE: Be sure the VOX DELAY control is
adjusted so the relays do not open after each character

After the dial is set to zero beat the calibrator signal, the
frequency of the CW output signai is 1000 Hz higher than
the dial reading, The received signal is actually in the USB
position even though the MODE switch is set at CW.
Consequently, cross-mode operation is possible between
USB and CW without any resetting of the MAIN TUNING
dial. For example, if two stations begin operation in the
USB mode of operation and one operator changes to CW,
the other station will hear a 1000 Hz note without retuning
his receiver, Also, the station operating in the CW made will
receiver the USB signal from the other station without
