I am 15 miles off Long Island Sound, I have a son in Oakland, California. My antenna at home is 40 feet of copper wire running north/south facing due east - a dozen feet off the ground. Facing east, there is virtually nothing but a 660' hill about a mile away. When in Oakland, I'm using a portable with its included longwire.
The Asian based transmissions (including the BBC) are an easy catch in Oakland and seldom gets in Connecticut. Among my Oakland gets in (check shortwave section HFU posts) late April 2019: Radio Nikkea, Voice of Korea, RNZI, KBS, Voice of Korea, Voice of Vietnam, NHK, FEBC, Voice of the People, KNLS, and KCBS. I did find the European/African broadcasters and pirates almost nonexistent out there. However, Radio Habana Cuba boomed in 🙄.
