I own several HF radios (FT-1000 MARKV full filter), ts-870, TS-940, and tons of vintage equipment (all of hybrid made by yaesu and kenwood), my last ICOM was IC-751A and IC-735 which was one of my favourite RTX.
The 7300 has the same size of the 735 and even if it hasn't the slidind door, i like it so much

.
I am testing the 7300 and at the moment i have no complaints about it.
There is no other HF rig of the same price range that can compete with it. Who will buy a TS-590 or a FT-DX1200 now? no way.
I was thinking of buying a mint icom 781 but i ended buying the 7300 to try this new kind of transceiver.
SDR technology is really awesome for the possibility it can offer to the operator, but i could not mentally support the idea to use my computer instead of a real radio. Using a PC for making audio communications is like using a flight simulator instead of real flying. I need to touch the radio, to rotate the controls and to ear the voice from a radio speaker instead of the PC speaker.
I don't' want to ear or see a facebook or email pop-up while i am ragchewing on the band.
I even not support the PC fans in the background.
So the 7300 is so interesting. I can do real SDR radio without a PC!
The receiver is very good, and the NR works great , also the NB is really effective. The 7300 is very ergonomic and simple to use, i have no complaints at the moment.
I have hooked the usb cable and it is very simple to operate all digital modes.
I have also tried the 12khz mode output thru usb and it's not a problem to use HDSDR or DRM software.
It's very nice to record the audio on the SD card it's a really nice feature for SWL.
The display is very sharp and bright (i still use it with the plastic protection) and the real time spectrum scope is really realtime not the slowmotion panadapter of the more expensive 7600 . here we have a realtime waterfall display , the same of the more expensive sdr radio of the market.
The Icom remote software let you control the 7300 by the internet and have a real remote station without any limitations.
I was planning to install a HF radio station on my RV so i can use radio when i am on holidays , now i have just to bring my laptop and 3G router to use my home station from RV.
I love boatanchors and my favorite radio are heavier that 5 or 6 7300 , i am really pleased with the performance of this rig.
