Figure 1 — CW keying waveform for the
FT 5000D showing the first two dits in full
DX
break-in (QSK) mode using external keying.
Equivalent keying speed is 60 WPM. The
upper trace is the actual key closure; the
lower trace is the RF envelope. (Note that
the first key closure starts at the left edge
of the figure.) Horizontal divisions are
10 ms. The transceiver was being operated
at 200 W output on the 14 MHz band.

DX
sideband testing. Equivalent keying speed
is 60 WPM using external keying. Spectrum
analyzer resolution bandwidth is 10 Hz,
and the sweep time is 30 seconds. The
transmitter was being operated at 200 W
PEP output on the 14 MHz band, and this
plot shows the transmitter output ±5 kHz
from the carrier. The reference level is
0 dBc, and the vertical scale is in dB.

composite-noise testing. Power output is
200 W on the 14 MHz band. The carrier, off
the left edge of the plot, is not shown. This
plot shows composite transmitted noise
100 Hz to 1 MHz from the carrier. The refer-
ence level is 0 dBc, and the vertical scale
is in dB.
