The IC-7300 is a revolutionary compact radio that will excite HF operators from beginners to experts. This new model has a high-performance real-time spectrum scope and employs a new 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.
The IC-7700 HF/50MHz transceiver shares many features with its 'big brother', the world famous IC-7800. With two independent DSP units, a +40dBm* 3rd order intercept point and ultra wide dynamic range to name but a few of the features.
Icom has developed the flagship model IC-7800 which is a fusion of forty years analogue RF circuit development expertise, with cutting edge digital technology.
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.
