Icom IC-9700: A Comprehensive Review

The Icom IC-9700 is a high-performance, VHF/UHF/SHF all-mode transceiver designed for serious amateur radio enthusiasts. Released as a companion to the popular IC-7300, the IC-9700 brings similar design philosophies to the VHF, UHF, and 23cm bands, offering a modern, feature-rich experience for operators interested in satellite communications, weak signal work, and more.

Key Features

Tri-Band Coverage:The IC-9700 covers the 144 MHz (VHF), 430/440 MHz (UHF), and 1200 MHz (23cm) bands, making it one of the few commercially available transceivers that include 23cm right out of the box.

Modes: Supports all common modes, including SSB, CW, AM, FM, and various digital modes, ensuring versatility for different operating preferences.

Direct Sampling:While the IC-9700 does not use direct sampling on VHF and UHF (like the IC-7300 on HF), it employs a similar technology for the 1200 MHz band. The direct sampling on 23cm allows for high precision and clarity in receiving signals.

Dual Watch and Full Duplex Operation:Dual Watch allows users to monitor two frequencies simultaneously, perfect for satellite operation. The full duplex capability is a standout feature, enabling simultaneous transmission and reception on different bands, critical for satellite and crossband repeat operations.

High-Resolution Touchscreen:The 4.3-inch color TFT touchscreen provides a user-friendly interface. The layout is intuitive, with large, easy-to-read icons and a responsive touch experience.
The waterfall display and real-time spectrum scope are among the best in class, offering a visual representation of signals across the band, aiding in signal identification and tuning.

High Stability and Accuracy:The IC-9700 is equipped with a high-stability OCXO (Oven-Controlled Crystal Oscillator), which is essential for stable operation on the 23cm band and during satellite communications where Doppler shift needs to be compensated.

Memory and Customization:The IC-9700 features 99 memory channels per band, each capable of storing various parameters, including frequency, mode, and more. Users can customize their experience, storing their preferred settings for quick recall.

RF Output Power:The IC-9700 delivers 100W on 144 MHz, 75W on 430/440 MHz, and 10W on 1200 MHz. This power output is ample for most applications, from local repeaters to weak signal work.

Satellite Functionality:With built-in satellite mode, operators can easily track and communicate through satellites. The full duplex operation and Doppler shift correction make the IC-9700 an ideal choice for satellite enthusiasts.

Connectivity:The IC-9700 includes USB, LAN, and CI-V interfaces, enabling remote control, digital mode operation, and integration with various software platforms. It also supports D-STAR, Icom's digital voice and data protocol, for digital communication on the VHF/UHF bands.

Audio and Signal Quality:The IC-9700 is known for its excellent audio quality on both transmit and receive. The AGC (Automatic Gain Control) is smooth, and the noise reduction features help pull weak signals out of the noise.

Performance

In practice, the IC-9700 shines in both terrestrial and satellite operations. The receiver is sensitive across all bands, with excellent selectivity and low noise figures, making it ideal for contesting, weak signal work, and DXing. The 1200 MHz band, often overlooked, is brought to life with the IC-9700's performance, offering a new avenue for exploration for many hams.

The real-time spectrum scope is a powerful tool, allowing operators to visualize signals across the band, making it easier to find and tune to active frequencies. The waterfall display complements this, showing signal history and helping identify weak or intermittent signals.

Build Quality

Icom has a reputation for solid build quality, and the IC-9700 is no exception. The radio has a sturdy, premium feel, with a well-designed front panel layout. The knobs and buttons are responsive, and the overall construction feels robust, suitable for both home stations and portable use.

Pros and Cons

Pros:

• Comprehensive tri-band coverage, including 23cm
• Full duplex operation for satellite work
• High-resolution touchscreen with excellent spectrum scope
• Solid RF performance with good output power
• Versatile connectivity options, including D-STAR
• Excellent build quality

Cons:

• The price point may be high for some operators, especially those who don't need 23cm.
• No direct sampling on VHF/UHF bands (unlike the IC-7300 on HF).
• Limited 10W output on the 23cm band may require an external amplifier for some applications.

Conclusion

The Icom IC-9700 is an outstanding transceiver for serious VHF/UHF/SHF operators. Its combination of features, performance, and build quality make it a top choice for those interested in satellite operations, weak signal work, and exploring the 23cm band. While it may not be the cheapest option on the market, its capabilities justify the investment for those who need a versatile and powerful tool in their shack. Whether you're a seasoned operator or looking to expand your amateur radio experience, the IC-9700 is a worthy addition to any station.
