Anchorage TV carrier in Germany ?

In the night of 30-June-08 UK DXers reported receiving transatlantic carriers on TV channel A2.
I gave it a try and found this very weak carrier on 55.239.982 at 22:50. At that time DX-Sherlock showed 6m skips northward, mainly to Svalbard



Around 23:50 very faint 60Hz sidebands appeared. I suspected it from the Carribean and to narrow down the direction I tried to move the antenna null in that direction, so NW should give a minmum. To my surprise the signal got stronger, and got strongest when the antenna finally pointed northward.



This shows a 3,5 minute stretch


At midnight the signal got strongest and then faded away, a little bit more strenght and I would have seen video.


So what was it?
I still suspected the 25Hz wide (= unstable) carrier coming from the Carribean, assuming Canada & US would use better transmitters. Cyrill suggested the signal coming from Anchorage, AL because the frequency matches. A bit far fetched I thought.

But then

Anchorage is likely at 7200 km (4500 miles). QTF about 350 degrees, see

JE7IDA has received it several times this season on 55.23999, once "wowing", see

http://www.big.or.jp:80/%7Eham/pubhtml/dxcl50.html

Here JE7IDA only quotes its frequency to the nearest 10Hz,

so it must be unstable to a few Hz.

Anchorage is also quoted as variable frequency, 55.23999V (June 10),

Watch out also for the Alaskan data tx on 40.68963

I remember at the time DXers on 11m were calling for "trans-polar" DX.

I have never heard this before on 11m.

Maps was showing northern skip at the time. Amazing conditions. Which I'd

checked it further at then time!

Congratulations Jurgen.

Conclusion
I don't have a final proof which should have been a video picture, but all indicators point to KTUU Anchorage Alaska.
It is a pitty that in Feb 2009 the US stops analog TV, so I will never have a chance of another trans-polar TV reception.

Thanks go to all who contributed arguments and facts, especially to Tony Mann.
