Page 46 FT-480R OPERATION MANUAL CW MODE OPERATION CW SPOTTING (ZERO-BEATING) "Spotting" (zeroing in on another CW station) is a handy technique for ensuring that you and the other station are precisely on the same frequency. TO USE CW SPOTTING: In CW mode, while pressing and holding the [ATT/IPO] button, the Spot tone will be heard and Spot tone frequency will show in the display. This tone corresponds to the pitch of your transmitted signal, and if you adjust the receiver frequency to match the pitch of the received CW signal to that of the Spot tone, your transmitted signal will be precisely matched to that of the other station. Release the [ATT/IPO] button to turn the Spot tone off. [ATT/IPO] button USING CW REVERSE If you experience a difficult interference situation, where an interfering station cannot readily be eliminated, you may wish to try receiving using the opposite sideband. This may throw the interfering station's frequency in a direction that may lend itself more readily to rejection. To start, let's use a typical example where you have set the CW mode (using the default "USB" injection: the " " and " " icon appear). Press and hold in the [MODE ] or [MODE ] " icon appears button for one second. The " instead of " ", indicating that the "LSB" injection side has now been selected.

[MODE ]/[MODE ] button In the illustration, Figure A demonstrates the normal CW injection setup, using the USB side. When the LNK 0 is selected, the CW sidetone volume level becomes the same as receiving audio volume level. (You may press the [HOME/RCL] button to reset the CW sidetone level to the factory default. ) 5. The " " icon returns to appear continuously.
