Then their antennas must be awfully directional, so they'd have to set their aim at about 300 degrees to hit me with that kind of strength. As it stands now, Brazil's Radio Nacional Amazonia comes in much stronger here, despite being farther away.
I have to rely on my R75 for S unit readings, because the Sangean portable's meter has a scale of 1 to 10, and I don't know what the equivalent would be in S units. Signals sound like they're the same strength on both radios, even though I'm not using an external antenna on the Sangean.
SWBC can no longer be counted on for DX, because so many of the stations are received through relays in the U.S. That takes some of the excitement out of it. The only truly distant stations I pick up, besides the one in Brazil, are BSKSA in Saudi Arabia, the Voice of Korea in N. Korea, the Voice of Greece and Radio Romania Intl. RNZI used to come in fairly strong here, but lately I'm not hearing them at all.
If I want DX I'm better off monitoring the ham bands. Voice is so much easier to make out in sideband mode that I wish all the broadcasters used it. The FT8 digital mode is even more reliable, decoding signals I can't even hear through the noise, but the transmissions are so short that there's virtually no content worth looking at besides the station IDs and locations.
