Steve,
there is a greyline between Seattle and Indian Ocean going roughly along the
70th meridian between 0100-0125 UTC. It corresponds nicely with location of
Diego Garcia which lays in that area: 6 dgr. South, 72 dgr. East (est.)
The greyline bends a little bit to north-east, so there is no greyline
between Seattle and Afghanistan at that time of the day.
So I would really suppose that the feeder is located in Diego Garcia.

This is supported by propagation charts for path between central Europe and
Indian Ocean.
The chart says that signals on 8 or 9 MHz should improve rapidly between
1300-1400 UTC. And that is really true - I am just observing the signal on
8700 kHz comming up stronger and stronger during last 30 minutes from
nothing to very good level (it is 1345 UTC at the moment).

So I would bet on Diego Garcia.

BTW - this morning I saw on our Prima TV a shot about psycho war in
Afghanistan. They showed some American aircrafts and radio technicians
tuning their transceivers (around 21400 kHz :-) ). In the shot the speaker
(not the technicians) was talking about dropped radios with "permanent
frequency and battery" - but what was interesting was a guy from the BBC
Monitoring (maybe Dave Kenny would know him) who said they were pesimistic
about airborne broadcasts to Afghanistan. He said that the way how the texts
and comments were written could easily irritate people in Afghanistan and
the music played is not the one which would fit today's situation in
Afghanistan.

It seems to be similar to a character of airborne broadcasts in 1999 in
Kosovo which I have been happy to receive daily from an aircraft flying
above Serbia/Kosovo almost 1000 km (700 miles) from my location and
broadcasting on 1003 kHz. I understand Serbian and I found the broadcasts a
very strong propaganda against Miloshevich, repeated again and again by
angry voices and bad language (probably the speakers were Serbs living for a
very long time in the U.S. - they had a strong American accent). Such a
broadcast sounds more like an enemy broadcast than anything else...
I am a bit suspicious that the U.S., a big nation living more or less within
its own world, have a problem to find a way how to speak to smaller nations,
living in distant locations of the Globe...
But that was not what I wanted to write about... I think the greyline was
the matter...sorry...

GOOD DX,
