The plant in question has six or perhaps seven Brown Boveri SK 53 F3
(motorized manual tuning, plate modulation) transmitters, installed around
1975. Has its exact location already being established? It is not at the
coordinates given by TDP, they refer to a point next to the Brazilia
airport (which got a new lane only after the images used by Microsoft
Virtual Earth had been taken). No transmitter site there or in the
surrounding area.

Is that the president has extinguished RadioBras, which was responsible
for the txs. Until it is decided which govt agency becomes legally
responsible for them, the txions, even if they continue, will be
precarious.

History Oct 1994: BRAZIL RadioBras has difficulties to synchronize two 250
kW txs at one frequency. Deutsche Welle relay in Spanish to SoAM at 2300-
0050 UTC is registered on 11810 kHz using two 250 kW txs in parallel. But
one tx moved up to 11813.1 kHz, causing a strong interfering whistle tone.

Actually it's one site, with separate transmitter buildings for SW and MW,
but they are fenced together and share one power substation, located
