Just letting you know that I just worked Sweden from Olympia WA on CW (Morse code) using a homemade radio from the 90s at 5 big watts to a longwire antenna up 40 feet in a tree.
Bear in mind that at this power level you could run 8 stations like mine off the light socket in your refrigerator. _Not_ the fridge itself. Just the light socket. (That's a 40W bulb.)
Because CW rules and sideband drools.
