I'm forwarding my reply to the ARDF discussion reflector to get more input...

It took me a bit to figure out what "MS" stood for, as my first thought
was meteor scatter, which didn't make sense: it's the IARU Region 2 
Monitoring System:

There are a lot of handheld 80M ARDF receiver designs out there.  The big 
question (to which I do not know the answer) is whether or not a handheld 
receiver designed to DF a 1-5 watt signal less than 10km away by groundwave 
would be entirely suitable for DFing a skywave signal that might be much, 
much weaker, etc.

And of course you probably want designs for 40M, 30M, 20M, 17M, 15M, 12M, and
10M, too...
