I was using a 70 foot longwire and a 6 foot ground rod I could also hear these signals with the portable radio whip antenna at a long distance from power lines and houses so I do beleive these signals are real they were active throughout March 2011 also heard woodpecker tapping and strange odd musical scales giong up into the ultrasnic ranges and guinea pig-like squeals going up in range. The activity lasted until April 3rd and have not heard it since.

OTH Radar, Over the Horizon Radar

You have my cat's full attention.

Could be radar, local QRM, signal sweep, or just your receiver

[calcvids]

Sounds like electrical interference
