CW/MORSE |
With a proper, manual or
electrónic key, the message is transmitted under the form of "
points and strokes " code/alphabet invented by Mr. Guglielmo
Morse to who if must also invents it radio-electric. Is therefore with
entire justice, he has known as the " Father of the
Rádio"

SATÉLLITE |
They are
Intercontinental or National communications that they around take off left
of repeaters placed in some satellites placed in the space of the Land.
Radioamadores highly specialized in electrónica, had been the pioneers in
this new type of communications that of nowadays is of generalized use. |
LUNAR RFLECTION |
With well direccionadas
equipment and specific antennas, many radioamadores Clearly obtain
spectacular contacts taking off broken of the position and " phase
" of our natural satellite - the MOON that technique is necessary
much and " carolice ". |
TELEVISION |
Many are the radioamadores
that spend part of its time sending and receiving television pictures the
long pitch, in the known type of picture as " Slow Scan ".
Currently it is already in practical, but still in desenvolvimente, the
local television destined only the fans, whose type of transmission is
assigned of " Fast Scan " |
DIGITALIS |
The Computers had
revolutionized in overwhelming way the modern societies, of the Plant to
the Office, of the Pharmacy to the Homes, nobody were exempt of its
influence and, clearly, also here, the radioamadores had been of the first
ones to be used to advantage of its potentialities. Thus, daily, thousands
and thousands of communications are done taking off left of the Computer
that, a on time to a small " Modem " codifies and decodifies the
messages that are sent and/or received with the existing equipment of
radio already. It is a wonder!!!!.
The used emissions more are: RTTY, CW, PACKET if well that many others are
available. Digital AMTOR and PACTOR are modalities that they also are of
hamradio use. |
