The Clarifier is frequently used for receiver offset tun-
ing. However, for DX pile-ups where the DX station is
using a split of less than 10 kHz, the TX Clarifier func-
tion is usually the quickest way to set the transmitter to
the desired offset frequency.

To listen to the pile-up calling the DX station, so as to
find the station currently being worked, you may press
the [RX CLAR] button. Once you have zeroed in on
the station calling the DX (use the SPOT function on
CW for precise alignment of your frequency), you may
then press the [RX CLAR] button again to cancel the
RX Clarifier, and return to reception on the DX station’s

When attempting to work a DX station on CW, in a split-
frequency pile-up, remember that a large number of other
stations may also be using Yaesu transceivers with capa-
bility similar to that of your FT-2000. On the DX side of
the pile-up, everyone calling precisely on the same CW
frequency will sound like a single tone! So you may have
more success if you use the RX Clarifier to find a hole in
the pile-up, instead of trying to zero-beat the last station
worked by the DX station.
