The ability to simultaneously monitor up to 4 freqs is going to be a huge selling point for small airports and heliports, FBO's etc. If this comes in under $800 I think it will be a good selling radio for that market and will probably induce me to get one too.
I would think most any airport, small or not, would already have the ability to monitor [and communicate on] multiple freqs - And they are also heavily into redundancy, so would not purchase a single receiver just because it could monitor 4 freqs at once ,, But they might indeed get one to compliment existing monitor only setups.
I wonder how it avoids audio conflicts when multiple freqs are active, separate output for every VFO I am guessing ?
I agree that it sounds intriguing and I also agree that research must have been done on its potential market, and that market is not the hobbyist market. My cutoff would be around $600 [unless it has some kind of hyper-search ability], in which case I would also be in for around $800.
