New ICOM 7300 Unboxing unbox video.
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.
RMDR and phase noise characteristics
The IC-7300’s RMDR is about 97dB* (typical value) improving the Phase Noise characteristics by about 15dB (at 1 kHz frequency separation). The superior Phase Noise characteristics reduce noise components for both receive and transmit signals.
* At 1 kHz frequency separation (received frequency: 14.2MHz, MODE: CW, IF BW: 500Hz)
15 discrete band-pass filters
The RF Direct Sampling is protected by an array of bandpass filters. The signal passes through one of the fifteen bandpass filters, where signals outside the passband are rejected. To reduce the insertion loss, the IC-7300 utilizes High Q factor coils.
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.

FT4 Mode - faster than ever
The WSJT Development Group has announced the “general availability” release of WSJT-X version 2.1.0. This major upgrade formally introduces the all new FT4 as a finished protocol for HF contesting. The Group is providing a separate WSJT-X version 2.1.0 installation package for 64-bit Windows that offers significant improvements in decoding speed. That is what I am using.
A detailed list of program changes since WSJT-X version 2.0.1 is included in the Release Notes. Installation packages for Windows, Linux, and Macintosh are available.
Visit the FT8/FT4/JT9: WSJT 2-Way Narrow Modes for Amateur Radio Facebook page for additional information: https://www.facebook.com/groups/FT8.Digital.Mode/
There is a 'Files' section that has great info (link in left sidebar)

Shameless performance that is addictive. Try it — you'll like it.
