Pulsars take a big dish and they aren't all that good as a standard. A
friend of mine proved that at Aricebo years and years ago.

I've vaguely heard that there are some new ham allocations in the works
below 500 KHz. How about setting up a beacon network that works like
LORAN, but at a different frequency. A simple downconverter could then
feed the signal into a LORAN receiver?
