*Preamp off/on: 505 kHz, –121/–128 dBm; 137 kHz, –116/–95 dBm; 30 kHz, –77/–66 dBm.
The preamp does not improve sensitivity below approximately 250 kHz.
**Receiver testing was performed with the bandwidth set to 500 Hz and the filter shape to sharp.
ARRL Product Review testing now includes Two-Tone IMD results at several signal levels.
Two-Tone, 3rd-Order Dynamic Range figures comparable to previous reviews are shown
on the first line in each group. The “IP3” column is the calculated Third-Order Intercept Point.
Second-order intercept points were determined using –97 dBm reference.
†
Single beat note. Reduces two beat notes by 40 dB with attack time of 230 ms.
‡
Default values, medium filter, sharp setting. Bandwidth is variable; smooth setting is available.
CW bandwidth varies with PBT and pitch control settings.
CW or RTTY and then hold MODE to access
the alternate mode.
For CW operation, pitch, sidetone level,
key type, break-in type, keyer speed and CW
sideband (LSB/USB) can all be configured.
For RTTY, the ’7200 includes a twin peak
filter, preset for 2125 Hz and 170 Hz shift;
three FSK mark tones, four shift widths and
selectable keying polarity are also available.
To further improve the flexibility of the
’7200, each mode (SSB, CW, RTTY and
AM) can be separately disabled. So, for ex-
ample, if your operating style doesn’t include
RTTY, you can disable it and it will not be
included when stepping through the modes.
The ’7200 also has a data mode for SSB and
AM. When activated, the modulation for SSB
and AM is taken from the
MOD input of the
accessory connector or the USB interface.
CW-R and RTTY-R, once selected, will
remain selected even after changing modes;
SSB mode defaults to the normal mode, LSB
on 160, 75/80 and 40 meters, USB elsewhere
for each go-around.
Figure 1 — CW keying waveform for
the IC-7200 showing the first two dits in
full-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 100 W
output on the 14 MHz band.
Figure 2 — Spectral display of the IC-
7200 transmitter during keying 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 100 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.
Figure 3 — Spectral display of the IC-7200
transmitter output during composite-noise
testing. Power output is 100 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 reference level
is 0 dBc, and the vertical scale is in dB.
