New technology is changing the way receivers are being designed and the IC-7300 is an industry first as an RF, Direct Sampling System is being used in an entry level HF radio. The ability to digitize RF before various receiver stages reduces the inherent noise that is generated in the different IF stages of a radio. We feel the performance of the ‘7300 will far exceed your expectations for a radio considered entry level.
Output power: |
100W (25W AM) | |
RX Frequencies: |
0.030-74.800 | |
Receiver type: |
Direct sampling |
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.
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)
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.
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.
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.
Scope system | FFT (Fast Fourier Transform) |
Sweep speed | Max. 30 frames/second (approx.), selectable from slow, mid or fast |
Span width | 5kHz–1000kHz |
Resolution | 1 pixel minimum (approximately) |
Waveform display area (vertical axis) | 80dB |
Reference level adjustment | –20dB to +20dB |
Peak level hold function (Max. hold) | ON/OFF/last 10 seconds |
Other functions | Averaging indication Touch screen operation VBW (Video Band Width) adjustment |

Received updates from MTC every step. Radio arrived fine, double boxed and BEAUTIFUL! Thanks Christine, Richard, Tammy & everyone else at this great ham store in Paris!!!

Well I'm not really sure what to say other than this radio exceeded my expectations. I haven't had my General ticket very long. I just got it back in July. To be quite honest I haven't been a ham very long either. I got my technician back in March of 2021 and have been going a little crazy with radios. But I love the hobby.
The 7300 was such a great addition to my Icom 5100 which I use for 2 meter and 70cm. They are both great performers. I didn't have a Hf antenna so I tuned up a wire in some pine trees around my house and have been making contacts on 20/40/and 80 meters. Just waiting to install my new Moonraker vertical Hf antenna to see how it really performs. Thanks MTC for both my base rigs.

I never give a 5 rating. Always room for improvement in anything. The 7300 by Icom gets high marks for ease of operation, all the things a serious operator or the casual rag chewer is going to love. Every custom adjustments and any filter you would like to engage. From narrow for CW to arm chair copy wide. Your number of profile for taylor made setups is limited only by the size of the SD card you have to store them on. Good radio for sub $1000 range. Get one

I have been pleasantly surprised with not only the performance of this compact rig, but the ease of use as well. I've always been more of a big rig no menu kind of operator, however, particularly with the touch screen and excellent menu organization, this is very enjoyable to use and has a very short learning curve compared to other rigs I've had. The value versus what you get is unbeatable. 73, Ken, KT7C.

Love this radio. The scope is awesome. Very intuitive controls. The sub menus take a little work to learn. The cost is right in line with what you get. As with most ICOMs the speaker could use a little work. I ordered the ICOM external speaker.

A good transceiver for both the beginner and the more experienced diex player. Very nice, adequate size and excellent audio. MTC treated me very well and the communication was excellent.

Truely innovative design, loaded with useful features. May be the best deal for an HF transceiver ever. Love it

So far going great. it is perfect for what I do. I mainly use digital modes and emergency comms. right size and right features for me.

I’m IN MY semi truck 80 percent of the time and ham radio has been a great company keeper for me; We run a lots of miles in the trucking industry; Having said that I had several hf rigs and the IC7300 plays well in my Big Rig; Very quiet as well as sensitive rx with powerful NB and TX is great, I am very satisfied with this radio; KI4IRS
