RBN instructions and tips
Beacons serve to indicate the band conditions through
the signal strength received from many different parts of the word.
Generally, beacons are automatic transmitting stations on fix
frequencies, mostly in CW. By listening on these frequencies,
one detects the actual band conditions. As example, the NCDXF
Beacon Network, which operates worldwide 18 different stations
that transmit every 3 minutes on the same frequency.
E.g. by listening on 14.100 Mhz one note the band conditions on 20m.
The RBN (Reverse Beacon Network) works just
in the opposite way.
Instead of operating a number of transmitting stations, a number
of automatic receiving stations are used to monitor the CW stations
on several bands. They receive a broad bandwidth, decode the
heard stations and communicate the heard call signs over the
Internet to a central point.
An intelligent software allows to decode the callsigns, measure
the signal strength, and filter the received data. This way, very
conclusive information about band conditions is obtained.
The automatic receiver stations are called Skimmer, and consist
of an SDR receiver, an intelligent software and the required
Internet connection.
Interesting:
I recommend e special sequence, which will a large number of
reports will be received from RBN.
A insturuction with graphic display of the RBN reports, and the
recommended sequence (ed. 25.Sept 2014).
The fasted way to get it, is by search with GOOGLE with:
"RBN-introduction.pdf"
