(Araucaria) Res: Reverse Beacon Network News

[Renner, PY7RP]

Luc,

O N1MM suporta spots vindo do cw skimmer?
Seria uma boa que os spots do cw skimmer aparecessem
no Band Map do N1MM ALÉM dos spots vindos
do DX Cluster.

Seria bem interessante deixar um SDR e um
pc dedicado ao skimmer num CQWW em 80m
ou 160m, já que nessas bandas os multipliers
são importantíssimos, right?

Caros,

Felipe, PY1NB e Pete, N4ZR estão liderando uma iniciativa para 
construção de uma rede de Skimmers - um software com capacidade de 
decodificar CW e distribuir o indicativo das estações ouvidas em uma 
rede parecida com a rede DXCluster.

Neste fim-de-semana vou fazer alguns experimentos com o Skimmer na 
ZY7C. Sugiro que todos que tenham um mínimo de conhecimentos em modos 
digitais (alias, quem faz Digital está preparado para rodar um node 
Skimmer) a tentarem integrar a rede Skimmer.

Abaixo um email do Pete com detalhes sobre como montar um node Skimmer 
sem a necessidade de usar um receptor SDR, pode-se usar o HF normal.

O benefício da rede Skimmer, ou rede "Reverse Beacon" como vem sendo 
chamada, será enorme para toda a comunidade DXista e Contesteira, e vai
muito além da discussão entre o bem e o mal.

The reverse beacon network has started to take off. As I write this, we 
have 8 CW Skimmer reverse beacons active, and 14 have been on the network 
in the last 24 hours. 20 and 40 meters are currently covered, and stations 
are active in the US east coast and midwest, as well as northern and 
southern Europe. The US west coast came on last night, and will be 
back. I have a promise that a station will be activated in VK-land soon.

Reverse beacons come and go at will. The network is constantly 
changing. You can find out which reverse beacons are active by going to 
http://skimmer.dxwatch.com/skimmers.php. See the spots pour in at 
http://skimmer.dxwatch.com.

Felipe, PY1NB has also activated a pretty sophisticated query capability on 
the main site at http://skimmer.dxwatch.com/ With a little thought, you 
can find out what is being heard by a given reverse beacon, by whom, on 
what bands, etc. For example, you can see what European stations were 
heard first on a given band on a given day in the US - F5RRS opened the 20M 
band today, all up and down the East Coast.

A couple of notes for prospective participants:

-- A wide-band receiver is not absolutely required to try out the reverse 
beacon idea. Download and install a trial copy of Skimmer 1.1 (you can do 
this again even if you downloaded a trial copy of version 1.0) from 
www.dxatlas.com. Download the "aggregator" from 
http://skimmer.dxwatch.com/downloads/skimmer_aggregator.zip. Connect a 
cable from the audio of your transceiver to the Line In jack on your sound 
card (any old sound card will work for this).

Run Skimmer and set it up in 3-KHz radio mode. Fill in the operator 
tab. Tune your radio to an area of activity on any band, and you should 
see CW streams on the Skimmer waterfall. Start the aggregator, and your 
spots will go to the network - that's all there is to it.

One caution - Skimmer works best if you use its frequency controls to 
change your radio's frequency - you will have to set up Omni-Rig for your 
radio, on the CAT tab in Skimmer's settings, and set up for computer 
control of your radio if you don't already have one. My experiments 
suggest that if you tune your radio with that big knob in the middle you 
will have to stop and wait a bit before Skimmer gets sorted out and starts 
decoding properly again.

-- Be sure you enter a 6-character grid square in the location field of the 
Operator tab in Skimmer. We will fix this, but for the moment, if you do 
not have a full 6-character grid, your spots will not be displayed by the 
server. If you don't know the last 2 characters of your grid, just use XX.

See you on the reverse beacon network?

73, Pete N4ZR
