Very interesting notes, Karel. What you say about shifting conditions 
is true. LA West coast below di equator is very rare in Italy and 
seems to follow long time cycle patterns. I can for instance recall 
the first and only log from Ecuador (Democracia 1290) in 1988, in a 
location non that close to the sea (the Po river valley, screened by 
mountains to the West and South) by Giuseppe Zella, perhaps the most 
skilled DX-er here. Curiously stations from below the equator tend to 
bypass your local sunrise factor, here, especially for spring equinox 
and winter conditions. On the sea in Deiva, Sestri Levante and 
Camogli, rarest stations from Brasil or Uruguay did rather come up 
during their dusk/sunset (Voz do Oeste or Radio Maldonado both on 
1560). Peru on 1390 seemed seemed to be favoured by a complete 
darkness path the other week in Deiva (Cpn on 1470 was closer to its 
sunset time, though); While it's true that Colombia in autumn and 
winter usually fades in late in the night, closer to our sunrise 
slot. That's almost invariably true for NA stations, even in late 
summer nights, while Canada and northern East Coast could pierce 
through right after their sunset (that was several years ago, now 
side channel QRM tends to prevent that).

I wouldn't call him or her "fanatical", wish I had time and 
opportunities to be one! That's just the point, as Rocco stressed in 
our reply to Jan-Erik. We're really just a few, scatterd individuals, 
with no organized and coordinated dx-pedition activities going on. 
Many of us live in crowded urban areas, where not that many 
neighborhood are noise-free enough (I think this holds true for Czeck 
Republic too). In this conditions no regular monitoring of what could 
really be heard is possible. I still remember our initial feeling, 
back in the mid Eighties, when we discovered the effect of wires 
strung on the seashores in Liguria, with carriers and modulation from 
Brasil or Venezual coming as early as 20.30 Utc in the winter. 
Nothing to compare with purely nordic conditions of course, but one 
of our colleagues' advantages is their regularity, especially with 
"institutions" like Lemmejoki.

Cheers,
Andy
