CW Pitch Setting and Spot Tone
In the CW mode (only), pressing the [SPOT] switch on the lower edge of the front panel activates the CW sidetone, which is also used as a spotting oscillator. The frequency of this tone is also (exactly) the fre- quency at which your transmitted signal will appear relative to that of the incoming sig- nal.
Therefore, if you match the pitch of the SPOT oscillator’s tone to the pitch of an incoming signal, you will be exactly “zero beat” with that station’s CW sig- nal. In a DX
transceiver’s SPOT tone with that of the station being worked by the DX station, so as to be “next in line” on the same frequency. This SPOT signal is centered in the receiver section’s IF passband, as well, which en- sures that you will not lose track of his signal when switching to a narrower filter. Of course, you must turn off the [SPOT] switch once frequency alignment has been completed.
The CW pitch can be set from 300 ~ 1050 Hz (in
To adjust the CW pitch (and SPOT tone along with it), press the [SPOT] switch, then rotate the PITCH con- trol to set the tone to the pitch you prefer, or that used by your TNC or CW decoder. If the sub display is en- abled for indication of the CW pitch, you can view the pitch frequency as you adjust it. The SPOT tone vol- ume can be adjusted using the SIDETONE potentiom- eter, accessible on the rear panel of the transceiver).
In addition to the spotting oscillator, the directional tuning meter provides a constant visual indication of any signal at the center of the IF passband (if not too weak). You can just tune so that the segment flashes in sync with the signal of interest when it is centered (see page 41).
