A good receiver, decent antenna(s), and an effective preselector.
What more could an SWLer ask for?
Well, there's always something MORE that we could use ... right?
So all it takes is some cash, a few electronic parts, basic tools, lots of
thought, and a tremendous amount of understanding from whoever is your
physical, moral, emotional, and intellectual custodian, keeper, master, boss,
and/or supervisor.

Mine is all that, and she also cooks, does the laundry, and cleans the house
- especially the rooms I don't often use ... and she actually allows some of
this stuff in the family room!

I'm truly blessed!
I hope you enjoy this site. In time it's going to get fairly large - maybe there
will be something that you can take from here to enhance the enjoyment of
this hobby. - Bob, N1KPR
