There is an interesting NASA report ion some research involving navigation receivers and interference (mostly from FM broadcast sources) which states that the most sensitive receivers where more affected (which makes a lot of sense of course). Partly based on this report my challenge was to make a navigation radio that would be sensitive yet robust with respect to interference. It can be done but you effectively have to throw away the traditional superhet receiver if you want to keep things manageable and embrace new ways of making receivers which avoid some of the issues by fundamental design. Luckily - just that is now possible using some relatively newly released chips and an almost enormous amount of pretty complex maths. As I mentioned earlier - a completely ridiculous effort to produce a simple AM receiver in the most complicated way possible. But once done, bits and bytes are cheap and the result is quite respectable... Rainier |
Rainier when will this radio be available in North America?

The N16 has just been released for production a few days ago - usually takes 3 to 4 months to first shipping unless there is an issue getting hold of some components - don't think there are any shortages at this point since it shares much of the circuitry with the V16. I'll probably send off a N16 in the next two or three weeks for FCC (not strictly required but makes it easier to get these things through customs). Rainier CEO MGL Avionics |
