Open Box Used Acceptable ICOM IC-7300 with MARS Mod SN02016910
Open Box Used Acceptable ICOM IC-7300 SN02016910. Radio has been used and has been MARS mod'd. Internal packaging is open and includes power cable/microphone and Manual does have some slight bends and stains.
The Icom IC-7300 is Icom's latest SDR HF/50 MHz Transceiver. It offers 100W of output power and receieves from 0.030 to 74.800 MHZ. It operates on SSB, CW, RTTY, AM and FM modes.
The Icom IC-7300 features a RF direct sampling system, 15 discrete band-pass filters, a real-time spectrum scope and a large 4.3" color touch screen display. Additional features of the IC-7300 include a built-in automatic antenna tuner, 101 channels, SD memory card slot and 3 CW functions. In the box you will find the IC-7300 transceiver, a HM-219 hand microphone, DC power cable, fuses and plugs along with a warranty card and manual.
Output power: 100W (25W AM)
RX Frequencies: 0.030-74.800
Receiver type: Direct sampling
RF direct sampling system
The IC-7300 employs an RF direct sampling system, where RF signals are directly convert to digital data. Then processed in the FPGA (Field-Programmable Gate Array), making it possible to simplify the circuit construction as well as reduce noise that can mask weak signals.
The new “IP+” improves the 3rd order intercept point (IP3) performance improving the ability to copy a weak signal that is adjacent to either a strong interfering signal. In this process, A/D converter is optimized to reduce or eliminate signal distortion.
Large color touch screen
The large 4.3” color TFT touch LCD offers intuitive operation of functions, settings, and various operational visual aids such as the band scope, waterfall function, and audio scope.
Like on the high-end rigs, the waterfall shows a change of signal strength over a period of time and allows you to find weak signals that may not be apparent on the spectrum scope.
Use the audio scope function to observe various AF TX/RX characteristics such as microphone compressor level, filter width, notch filter width and keying waveform in the CW mode. Image below shows the Audio scope with the waterfall function and the oscilloscope.
Real-Time spectrum scope
You no longer have to choose whether to listen to the audio or have the spectrum scope sweep for signals as the IC-7300’s real-time spectrum scope offers the simultaneous operations found in some of the more expensive rigs! This means you can use either the spectrum scope or the waterfall to quickly move to an intended signal while listening to the receiver audio. The ‘7300’s touch screen introduces a “Magnify” function. So, when you first touch the scope screen around the intended signal, the touched part is magnified. A second touch of the scope screen changes the operating frequency and allows you to accurately tune.
