    dose sun spot activity effect long wave propagation? If not what dose? I use a large loop anteanna with very good results for receiving . Also I keep receiving a signal @225kc in code, _... ..../ bh. Any ideas? Very curious.

    No, sunspots do not affect LF propagation. Two big factors are:
    -Geomagnetic activity
    -Lightning noise levels

    Actually, BH is on 224 kHz. It is the NDB (non directional beacon) for the Birmingham, Alabama, Shuttlesworth International Airport (BH for "Birmingham").

    Thanks. That answers that guestion!
    I really injoy listening to LF . Started out using the sound card on an old laptop. Worked for the VLF but not the LF. Even drove copper rods in the ground for antenna.
