3. Turn the AF GAIN knob and allow the Transceiver to
warm up.
4. Adjust the AF GAIN contro! clockwise until some
receiver noise is heard.
5. Set the FILTER switch to SSB or CW, as appropriate.
if an extremely strony station overloads the receiver front
end, leave the AF GAIN control set for comfortable
listening; then adjust the receiver ievei with the RF GAIN
control. This will keep the front end from overloading and
masking weaker signals.
The § Meter will move with adjustment of the RF GAIN
control, but will still read correctly with the RF GAIN set at
eUrL ead COrmecet
less than maximum (if the received signal level is high
enough to register on the S Meter). For example, if the RF
GAIN control is set for no-signal meter reading of S5, and
the meter registers SQ with a signal. then the received sianal
er registers SQ with a signal, then the received signal
is S9.
6. The Transceiver is now ready to receive. Turn the
BAND switch to select the desired 500 kHz band
segment. The frequency of the tuned signal is
determined by adding together the settings of the
BAND switch, and the circular dial.
7. Peak the DRIVER PRESELECTOR for maximum
signal.
8. Set the FUNCTION switch to CAL. Rotate the MAIN
TUNING dial (VFO) to the nearest 100 kHz point on
the circular dial.
9. Adjust the MAIN TUNING dial until the calibrate
signal is at zero beat. (To be sure that the correct
calibrate signal is being used, check the DRIVER
PRESELECTOR tuning. !f the signal strength varies,
you are tuned to the correct calibrator signal.)
TRANSMITTER SECTION
WARNING: Portions of each band are for CW operation
only. DO NOT operate the Transceiver with voice
modulation in any portion of a CW subband. To do so (in
the U.S.A.) will invite disciplinary action by the Federal
Communications Commission,

transmitting frequency could be 14.4 MHz, which is out of
the amateur band. Checking with the built-in calibrator can
insure that the circular dial is exactly on a 100 kHz point,
but you cannot be sure which one it is on. Therefore, before
transmitting, make sure you hear other amateur signals on
both sides of your chosen frequency. If you do not, check
your dial by turning the MAIN TUNING KNOB
counterclockwise to the end of its travel. The circular dial
should now be at the “500” end of its scale (refer to Detia!
8-9B). If the calibration is correct for one band, it will be
correct for the other bands.
