Airplane scatter logging

[crainbebo]

Today in Bothell, WA, I got Daughtry's "What about Now" on 95.3 FM. Could this be CKZZ Vancouver or E-skip?

Other loggings from airplane scatter
105.7: CBU Vancouver
PERFECTLY!!!!!
87.7: CHEK-TV Victoria with news

I don't think airplane scatter would be stable enough to log any DX since planes are relatively small and move fast. You'd have better luck logging "DX" from inside the airplane.

I used to notice airplane scatter when I lived in a rented house on final approach.
I would pick up distant VHF TV stations on my analog set, but it would only last for a
few seconds until the plane passed. Was almost like having my own primitive radar station.

I sometimes look for airplanes up in the sky for any airplane scatter... ;D

In Sutherlin, OR, west of the Cascades, I once heard KLTW 95.1 Prineville, OR 110 miles away on the other side of the Cascades for a few seconds...these mountains normally block the central OR FM signals OR from reaching the Sutherlin-Roseburg area.

If anything, I've noticed passing aircraft destabilizing stations that you're hearing courtesy of tropospheric ducting. They're coming in fine, then as the plane passes over, the signal wavers madly from strong to weak. The signal becomes stable again a minute or two after the plane has gone. Usually low-flying aircraft do this (< 3000') and never have I seen it cause a previously unheard signal to suddenly come because of it.

I've lived right under the flight path for the Memphis airport before. Airplanes can do one of two things, either make what you're DXing fade out, or make another station come in. For example, you could be hearing the 105.1 out of Little Rock, and if a plane flies over it could change to the 105.1 near Jackson, MS. Other times a station could bounce off the plane and come in for a few seconds when there was nothing coming in before.

Tropo is caused by a temperature inversion. Colder air is near the surface and warmer air is higher up. Jet engine exhaust is hot, and that temporarily disrupts the inversion.
