Weird Bomber Noise on shortwave 4310khz? -4400khz 05:05utc 3/29/11

I heard this very strong S9 humming signal kind of like a large fleet of world war 2 bombers with their massive three bladed propellers it slowly drifted up in frequency then would drop down in frequency first heard it on my homebuilt crystal radio with SW first heard on 5740khz area. The crystal radio has very poor selectivity which allowed it to be tuned in without having to follow it up in frequency It sounded pretty cool running through my guitar amp . Later I heard it again on 4310 to 4400khz this time I used my Realistic DX390 in SSB mode. it continued until about 05:50utc .Never heard anything like it before??

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.

What are you using for an Antenna and ground?

it sounds like aboriginal music.

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

[calcvids]

Sounds like electrical interference
