Icom 7300 Specs Important To Me


Waiting on the delivery of my new Icom 7300. It should be here in a week or two. I have been looking at the manual and other papers on this radio, as well as other websites. Here are a some of the Icom 7300 specs. This is what I’m looking for in a radio (*).

Icom 7300 Specs

The Innovative HF Transceiver

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.

*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.

*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.

*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.

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

    I saw Ham Nation where they had the IC7300 on and the radio will do 100% duty given that everything is wonderful with the world, and we do not do things like psk31 at anywhere more than say 5-10 watts. no, I am not saying that this is the unkillable digital radio, but it looks like an awesome HF rig, I do not have the bucks anymore having bitten on the ic7100 that I purchased for doing digital, with 1hz tuning, all the modes and all the bands I use, I bought it fully knowing that I was going to be running it with things like hrd and wsjt-x. Had I 2000 bucks in the shack spending account, I could see buying it and a dual band rig for vhf/uhf.

      Hi B.T.,
      I think I saw the same Ham Nation video. I had already put my reservation in, so I am pleased to see clips like that showing some of the Icom 7300 capabilities. So far, so good. The way I see it, it’s always a risk buying a new, first gen radio. It’s safer to wait. I have an Icom 7000 that I just put in my vehicle for full time use. I like the LCD on that rig and it has been a good reliable radio. I’ll be selling my Flex 1500. I love PowerSDR and using the waterfall/panascope. It’s fantastic. I hope to get the Icom 7300 running something like HDSDR eventually.

      When I get the 7300 I’ll do some videos on it. Thanks for dropping by and commenting. Hope to hear you on the band, 73 good DX. – Rich, K0PIR

    The IC 7300 has a lot of internally-generated noise…what can be done about this??

    • K0PIR says:

      Hi Steve,

      It’s nice to hear from you and I hope all is well where you are and I hope you and your family are good.

      I don’t get any internally-generated noise. Maybe it is something locally. The NB and NR work well on it. PCs can be a problem. See this, maybe it is similar to what you are experiencing.

      I am using a ferrite kit for the lines going into my ICOM radios.

      I hope you can find the cause of the noise, be safe and best 73!

      Rich, K0PIR
