I was reading some reviews and discussion about the IC-7300 radio. The sentiment was always something that it was an "SDR in a box" or "glorified SDR". I know that the IC-7300 uses direct RF sampling instead of the more traditional superhet technology. Is that basically it? Are these rigs really that bad? Everything is software defined these days- even your cell phone (it's literally an app). I've been interested in that particular model radio- but all the bad things said about it make me think twice and second guess.
