How about a long carrier, GPS or rubidium? It's a long shot but it's a low loss path and the time of year is good for several hours of coherent integration. I can easily see 10uW from 1000km in one hour over a path with a lot of land. West to east over water will be lower loss and four or six hours integration will make up for the lower ERP. -- Paul Nicholson --
