Hello ED and al
> Any idea on what kind of TX power is being used for the weather satellites?
In case of NOAA POES - APT trasmision:
" ...The signal itself is a 256-level amplitude
which is then frequency
carrier <http://en.wikipedia.org/wiki/Carrier_wave>. Maximum subcarrier
modulation is 87% (±5%), and overall RF bandwidth is 34KHz. On NOAA POES
vehicles, the signal is broadcast at approximately
40dBm<http://en.wikipedia.org/wiki/DBm>(10 watts) effective
radiated power <http://en.wikipedia.org/wiki/Effective_radiated_power>."
