IC-7200

NEW IC-7200 HF/50 MHz

Once again, we are honored to present a new Icom HF/6m transceiver in advance of the 2008 Dayton Hamvention.

The forthcoming IC-7200 HF/50MHz transceiver is aimed at a wide Amateur audience.

For a beginner looking to buy an inexpensive HF radio, or a HF radio operator looking

for a compact IF DSP radio, the IC-7200 is a perfect purchase.

Planned Features - Simple user interface

The IC-7200's simple layout makes it exceptionally easy to use.

Experienced operators will find the functionality of the IC-7200 very intuitive.

Ideal for indoor and outdoor use

The IC-7200 features military styling, which makes its suitable for all round use.

IF DSP and Twin PBT

The IC-7200 brings the benefits of IF DSP including digital noise reduction and adjustable bandwidth

(no additional filters) as well as the Icoms traditional Twin Pass Band Tuning.

USB port for PC control

In addition to the retained CI-V interface, the radio can be controlled with direct USB connection to a Windows PC

Display of IC - 7200

IC-7200, USB connector on the back. Is this the first ICOM radio being capable of CI-V
data format, and modulator - received audio over the USB cable! Audio via USB would
be fine for digital modes. RX standby current drain 1.3A, i was hoping for much less, darn
these DSP chips at 15.625 kHz on 3th IF.

AGC loop management

Distortion and blocking from strong nearby signals are prevented by placing DSP functions inside the AGC loop. The AGC time constants are selectable from fast, slow and off for each operating mode.

High stability transmitter

The DDS (Direct digital synthesizer) creates a clear, clean transmit signal and improves the C/N ratio. With a dual-fan cooling system, the IC-7200 provides stable high quality output even during high duty cycle operation.

USB port for PC control

The IC-7200 can be controlled by a PC through a USB port using the CI-V data format. In addition, modulator and received audio can also be transferred over the USB cable. By using appropriate external software, you can record incoming call and/or transmit preprogrammed messages from your PC.

What, no ATU? It will be noted that the IC-7200 is not equipped with an internal ATU.

This makes a lot of sense in an entry-level transceiver; by omitting the internal tuner

limited to a 3:1 VSWR range, the radio manufacturer can pack more performance

into a smaller, simpler package and allow the user to select an ATU as required.

IC-7200 - Structural examination and components of transmitter PA Unit and Front Display. The new, compact transceiver from ICOM the PA is similar to that employed in the well-known FT-2000. In effect, as can be seen clearly from the two juxtaposed pictures (below), the PA uses 2 Mitsubishi RD100HHF1 MOSFET's in push-pull, with Vdd = 13.8V.
