BC-DX 789 05 Jan 2007 Private Verwendung der Meldun

6075 was again a distaser this morning until Sines left at 0755. The kind
of echo is similar to the multipath echo we simetimes hear from distant
stations on high frequencies. Although the echo was very slight when RMP
started in the evening, it became more prominent later in the night, and
reached a degree where it was quite disturbing. It would seem to be a
better idea to run two transmitters at Sines in//at diffent azimuths
during the night.

NG: Maybe Moosbrunn would be a better site in midday?
I don't know how 6155 performs elsewhere in Europe, but it should indeed
be possible: Moosbrunn has a second HQ antenna, at present in use only for
30 minutes of AWR German a day, and this will go when the B06 season
ceases.
NG: But at re-check 1445 UT 6075 was up to 9+20 and a steady signal - am I
"suddenly" hearing a ground wave signal for some reason?
You are about 80 km away from Skelton, right? I think at this distance
groundwave can be certainly ruled out.
NG: Is WER still on air?
Yes, and just today they started a greater amount of AWR transmissions
which were on air from Al-Dhabbaya until yesterday. So things can go the
other way round as well, or as somebody put it: Don't be afraid, they will
not starve.

6075 Sines/Skelton synchro messed up.
6075, next act: At 1700 UT suddenly a second audio signal appeared on
6075, 1.3 seconds ahead of the running one. This must be Sines, coming on
6075 as scheduled, which also means that Skelton has the delayed audio.
Until yesterday 6075 was daily from 1700 a synchro operation of Wertachtal
and Sines. The carriers were locked to the same reference (I think GPS),
and audio was kept in synch by catching modulation with identical
equipment (some receiver which is more or less a common standard for
professional applications, can't remember the brand right now) from the
very same source (Hotbird 6, transponder 155).
Apparently the Skelton and Sines carriers are now locked as well, at least
there are no signs of any SAH. A possible scenario for the 1.3 seconds
delay: VTC feeds 6075 in their usual manner, by picking up the source at
Bush House in London and routing it through their internal distribution
system, resulting in another satellite hop with another encoding/decoding
procedure. If so it would be really a poor idea, no matter that "we always
do it this way". Didn't they pride the flexible service offered to DW?
Anyway the result is an absolutely unlistenable mess, and I'm curious how
long this situation will persist.
A quick-and-dirty recording (sorry for the noise level) can again be found
in the Yahoo group.

Frequency 6075 certainly has aroused much interest after years of just
"being there" every day. And satellites/isdn lines have certainly
introduced more complexity into operations that the DW/VT is attempting.
But then, it used to be "fun" for we dxers to hear some of the direct
'off-air' relays that the BBC, VOA and RFE/RL attempted in days gone by.
