full French transcripts on the next page.I did not realize Djibouti
was so mountainous, even above the timber line, judging from the
only illustration on the website. Hints it may be based in Colorado?

VANUATU An update on the new frequency from Vanuatu. Adrian Sainsbury,
Frequency Manager at RNZI advises that yesterday was the first day on 5055
kHz and the transmitter is only 1.5 kw on 5055 kHz at present. It will be
operating 24 hours a day over the next few days (open carrier noted at
1815 UTC but nothing evident at 0515 UTC check).
Adrian also advises there will be some tests on 7260 kHz at some stage.

5055.000 Radio Vanuatu, at 0740 UT, Pidgin, fading-in with talk by a
woman and island music. Parallel 3945 kHz. So, I wonder if 7260 kHz is
also on the air? Feb 19.
And this I have on 5054.973 kHz? 1.5 kW only.

5055 R. Vanuatu recorded from 0700 to 1100 UT on Febr 21. Barely
discernable audio at half-hour checks. Seemed best after 0930 to 1100 UT
stop. QRM from 5050 kHz started at 0957.5 UT. If I could have seen the QRM
pattern, the Perseus could have been set to eliminate the adjt channel
QRM. Will try that with a later recording from 1100 to 1400 UT tonight.
Vanuatu OFF air on Feb 23, but on air again Feb 24th.

125ms - round-the-world-echoes -, comment by Nils to Glenn Hauser.
Nils' paper doesn't deal with "real" RTW signals, but with "near" RTW
signals. This means: transmitter & receiver are not at exactly the same
place, but about 600 km apart. This also is the scenario, for which the
cited paper is valid.
The results are a follows:
- with transmitter and receiver some 700 km apart, the short path goes its
textbook way, whereas the long path goes a crooked way. This way is some
2500 km shorter than that of the textbook long path.
This is, what Nils found.
- with transmitter and receiver being apart a couple of 1000 km, the
textbook version of long and short path seem to work properly
Nils' paper gives examples for both cases.
