Re: Misuse of the satellite bands



Hello Sangat and Chritoffersen

- Hi and I must say excellent report from Ib.
- Our situation is not much better, in the sat band in VHF you find spurios
transmissions
from overloaded / mistuned FM broadcast stations, a net of pirat stations
working in UHF
436.290 (SO35 up link), wich can be outruled with the beam antenna, and
local police
working a repeater in 144.590, and many other wich I do not remember at this
moment.
- The Brazilian Goverment Agency, ANATEL ruling the use of radio and
spectrum is to-
tally inactive in this matter, doing absolutely nothing due to unknown
reasons, they are
working only as tax collectors and you receive mail fron them only if you
did not payed
you license.
Regards and luck
Nicolau, PP8DA
