Thanks for the ARS TECHNICA link, conachair. I think that article is great background and lays out the potential of SDR reasonably well. The comments are an education as well (if you skip the Apple bunfights)
I do think that it underscores the fact that SDR right now is mainly a development tool and (not counting military use) that new devices, protocols and uses will eventually come out of work started now. But it's also important to note that it would take hundreds to thousands of dollars and often bulky SDR and computer hardware
to duplicate today the functionality of a $200 VHF
transceiver, or a $120 GPS
, or a $100 AIS
receiver... and the SDR versions would not be as robust, dependable or efficient as the lower-priced dedicated units. I mention this only because this is a cruising forum, and our electronic aids must work in our conditions. A boat isn't a lab bench or backyard shed.

economy is declining. Not to be concerned, the higher end customers need integration efforts and that level of business will remain. A good waterproof tablet with say linux
or android which the end customer never sees anyways is a very viable integration platform. Comments most welcomed as I love this stuff..
The rugged unit will eventually appear. I've often toyed with picking up something like a Panasonic Toughbook to have as a go-anywhere test bed
, but my "research" budget
can't yet accomodate the price
, even for a used one. I make do with some ASUS eee netbooks which are reasonably durable (so far) and good value, but certainly not marine-survivable platforms.
I wouldn't be surprised to find that the Raymarines of the world are already working on a "marinized" tablet display or similar, together with a rugged dedicated central processor, that would be the platform for the next generation of marine
