Default dxAce, are your antennas by the lake?

so damn many locals at night here in Florida, it is hard for foreign
stations to break through!


Bob, it's not the "ocean" effect, it's the "sea gain" effect and it
operates only on MW mediumwave. It does this over the salt sea water -
it is not clear if it works over freshwater like dxAce's lake
Michigan.

Sea gain does not seem to work for SW, only MW. It was first
discovered and written up in scientific papers by British BBC
engineers 60 years ago.

Bob I'm sorry you don't get any TA reception on MW = you should, even
on your Redsun RP2100 if you take it down to the beach one evening at
sunset. Give it a try.
