The > conventional wisdom in most industries is This is the commercial point of view. I compare this to the Microsoft-approach. They need lots of money for producing, testing and supporting operating systems and Office. You can get similar for free with Linux and OpenOffice, both using older abandoned software parts, recycled, collected from public domain, contributions from companies that want to improve certain functions (more cost effective than creating a new operating system from start) .... > that for small-scale stuff, the MSRP should be roughly 10 times (yes, TEN) > the raw BOM costs, in order for > you to not go broke in the first couple of years. For mass-produced items, > margins can be allowed to slip into This is commercial thinking. For hobby or student projects you don't ask if it's profitable or not. It's just for fun or for educational purpose. The SSRP receiver board was about $120. So, what's the risk of bankruptcy ? > streamlined and optimized for cost. But *in no way* is developmental SDR > hardware in the "mass produced" That's why it is more expensive than my cheap GSM mobile phone, $30 with lots of digital/RF electronics included. I think for $100-$300 you could build a good SDR with mass-market chips (USRP uses quite common chips), affordable for students and hobbyists, with certain trade-offs regarding maximum performance.
