AH-730 Automatic Antenna Tuner The AH-730 HF Automatic Antenna Tuner can be used with a variety of Icom HF Amateur radios. Wide Frequency Coverage
With a 7 m (23 ft) or longer wire element, all band matching is possible from 1.8 MHz (160 m) band to 50 MHz (6 m). The AH-730 is highly efficient for multi-band operation.
* A ground connection is required. High-Speed Tuning
The automatic tuning operation can be made at a high speed of about 2 to 3 seconds. It has 45 memories to store the minimum SWR settings. When re-tuning the same frequency, matching can be achieved in about 1 second. Minimum RF Output for Tuning
The AH-730 emits only 0.3 W of RF output from the antenna during tuning operation. The low power minimises the risk of interference to other stations while matching the antenna. IPX4 Water-Resistant
The tuner case uses a high-strength resin that protects internal parts from water, weather, and salt damage. The tuner is tested to IPX4 water splash protection. In addition, the coaxial cable and control cable can be easily connected without opening the case.
In 1995, almost two decades ago, Icom changed the way radio hams thought about mobile HF communication with the introduction of the IC-706. Since that time, the Icom Mobile HF radios have been the Performance HF mobile radio of choice. Now, at the 2012 Tokyo Hamfair, Icom has once again changed mobile HF communications with the introduction of the IC-7100.
Aimed as an entry-level product, the IC-718 continues all the traditions of high quality engineering that you would expect from Icom. Conveniently sized and easy to operate, the IC-718 utilises all the latest RF and digital technology and is designed to be one of the most practical rigs ever! The IC-718 offers an excellent overall specification coupled with ease of use. The first thing that strikes you about the IC-718 is its similarity to the IC-R75 and more importantly that the speaker is mounted on the front panel of the transceiver. With the speaker facing the operator audio can now be more clearly heard during operation.
The IC-7300 is a revolutionary compact radio that will excite HF operators from beginners to experts. This model has a high-performance real-time spectrum scope and employs a RF direct sampling system. The IC-7300’s real-time spectrum scope provides top-level performance in resolution, sweep speed and dynamic range. While listening to received audio, the operator can check the real-time spectrum scope and quickly move to the intended signal. The combination of the real-time spectrum scope and waterfall function improves the quality and efficiency of HF operation.
Whether it is poor band conditions, or battling to pick out a call in a large pile-up, faint signals have always been a challenge for DXers and Contesters around the world. The difference between putting the QSO in the log or having to try another time is the capability of your receiver. One key factor is the RMDR capabilities, the ability to pick out a faint signal in the presence of stronger, adjacent signals. The IC-7610 introduces dual RF direct sampling receivers, achieving 110dB RMDR, rivalling that of top-of-the-line transceivers.
