IC-PW2
The IC-PW2 has succeeded in realising the world's first*1 DPD as a linear amplifier for amateur radio in combination with the IC-7610. This technology corrects the signal distortion from the IC-PW2 by applying inverse distortion to the output signal from the IC-7610 exciter in advance*2.
*1 According to Icom research as of July 2023.
*2 Not applied in non-linear modulation such as FM, FSK, and MSK modes. 2 × 6 Automatic Antenna Selector
Two radio inputs and six antenna connectors provide fully automatic antenna switching capabilities. Each antenna can be selected independently when changing a band on either transceiver. You can operate it as if you had two linear amplifiers. When using dual independent receivers, which the IC-7610 and IC-7851 have, you can watch dual bands at once by using two antennas. Powerful SO2R Features
Single Operator Two Radios (SO2R) operation is possible with one IC-PW2. While calling on one radio*1, you can watch another band on the other. The transmitter lockout function*2 prevents simultaneous transmission of two radios during SO2R operation.
*1 Performance may deteriorate depending on the performance/specifications of the BPF and exciter, antenna installation conditions, and other factors. In such cases, please take measures such as using two sets of BPFs.
*2 Compatible Radio linked operation is available with IC-7851, IC-7610, and IC-7300 (firmware upgrade required.) SO2R Operation Possible with Just One Multi-band BPF
Conventional linear amplifiers require two multi-band BPFs to prevent suppression of receive sensitivity by their own transmit signal when operating SO2R. However, the IC-PW2 automatically connects the multi-band BPF to the receiving radio when you select either radio to transmit. This makes SO2R operation possible with just one Multi-band BPF*.
* Performance may deteriorate depending on the performance/specifications of the BPF and exciter, antenna installation conditions, and other factors. In such cases, please take measures such as using two sets of BPFs. RX-ANT Connectors for Multi-band BPF and External Equipment
User supplied bandpass filters (BPF), preamps and attenuators can be connected to the [RX-ANT] connectors. When you use two radios with the IC-PW2, one multi-band BPF can be shared with these radios by switching the receiving radio. In addition, the band switching of multi-band BPF can be controlled from the band signal output connector. [BAND 1] and, [BAND 2] signal output connectors can each be set to either [INPUT 1], [INPUT 2], transmitter side, or receiver side. It can be linked with band switching of various external devices. Completely Linked with Icom Radio Operation*
With compatible Icom radios, various settings are easily made so you can get the full performance out of the IC-PW2. When you operate the transceiver by changing bands and frequency tuning, the IC-PW2 automatically works in conjunction with it. It provides an extremely quick response in contests and multi-band operations.
* Compatible Radio linked operation is available with IC-7851, IC-7610, and IC-7300 (firmware upgrade required.) Built-in Automatic Antenna Tuner
By using mechanical relays, the antenna tuner can quickly retune the operating band in two to three seconds. The IC-PW2 has also succeeded in reducing unnecessary emissions during tuning. The antenna tuner works even when the power amplifier function is not used. Detachable Controller with Colour Touch Screen Display
A remote-control cable (3 m, 9.8 ft) enables the amplifier to be mounted away from the radios for a big station installation. The 4.3-inch touch screen colour display provides a graphical user interface. Connected antennas are graphically shown on the display. Supplied Accessories

- IC-7100
In 1995, almost three 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, Icom has once again changed mobile HF communications with the introduction of the IC-7100. - IC-7300
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. - IC-7610
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. - IC-7760
In today’s connected world, the IC-7760 introduces a new connected system consisting of a remote control head and RF deck connected with a commercially available control (LAN) cable. This concept increases the flexibility of your station installation, making more space available on the desktop by placing the RF deck in an area closer to the antenna feed point. In addition to the direct connect feature, control head to RF deck, utilise your home network to make any tabletop your shack and a PC is not required! - IC-7851
Contesters and DXers are always looking for that competitive edge to magically pull out the weak signal that is either that rare country or multiplier they need to climb up the list. Larger antennas, higher gain pre-amps and other devices in line are great. However, what happens inside the radio with all those signals coming down your feedline can defeat all your efforts. - OPC-2501
