Kalundborg longwave antenna work
Kalundborg 243 kHz: A face lift will remove the top structures that in 1954 were added to the towers, which are 118 meters high freestanding, grounded, steel framework pylon towers.

The 2 towers in front carry longwave
243 kHz (but only until Feb 14, 2007 2330 UTC), and the tower in the back-ground carries mediumwave 1062 kHz.

Radio Itatiaia
Here is a photo of the new antenna at the new site of R. Itatiaia, 610 kHz, Belo
Horizonte, MG, Brasil.  (It's on a fairly steep sidehill, which explains the interesting perspective!)
This is now in operation 24/7 except for short periods of return to the old site to allow additional construction.  The associated HF, on 5970 or so, will be moved over to this new site within the next couple of months as well.
It might be possible for DX'ers in W. Europe to hear this one, as 610 is 2 kHz off the Region I & III frequency spacing, and it is 100 kW with a cardioid pattern whose maximum lobe is true north from S 19 59 W 43 53, and the radiated field over the arc from north east to NE (45 deg. T.) is over 4400 mV/m @ 1 km.
