The HF DF Rig here is a preamplified resonant shielded Ferrite loop feeding a Radio Shack Model DX-400. The preamplifier can be seen on the left.

The "Ferrite Beam" positioned for maximum signal on my favorite Southern CA stations.
High Frequency radio direction finding is quite a challenge. Weak signals, rapid QSB, brevity of ssb transmissions, varing angles of arrival, all combine to exasperate the would be HF radio direction finding enthusiast!

From here in Davis CA, On 40 meter SSB, I get good maximum signal strength readings from the LA/Orange County area at approx. 140 degrees, most of the time, with some interesting exceptions.
The unidentified politico-sexual psycho jammer station, commonly known as "Ralph" or "The Raghead" also seems to come from the same general direction. He could be a little further to the East but the equipment's lack of angular resolution, at this Northern distance, does not help.

When Southern California signals are weak, I get a peculiar anomaly in the reading. Many times, the signals actually peak to the North East, at about 35 to 40 degrees. This could be off by 180 degrees, due to the bidirectional pick up pattern of the antenna. I have theorized that this could be a reflection off of the High Sierra, from the Vaca Mountains 10 miles to my West (or a resonant metal light pole just over my backyard fence). The ferrite loop aimed at the possible reflection
