Registar QSOs SOTA no Log4OM e produzir o ficheiro CSV para upload automático….

Configuração SOTA

Convém criar uma configuração para o SOTA…

Faz-se – primeiro – um cópia da configuração existente  (indicativo, nome, etc.…

Assim, clica-se no símbolo indicado…

Abre-se a janela de definições e escolhe-se Clone Config

A página de definições fica aberta.

Substitui-se o nome pela designação da nova configuração…

Acrescenta-se o cume activado e demais detalhes…

Grava-se (ícone da disquete)…

Escolhe-se o perfil desejado para registar os QSOs (neste caso escolhi o perfil CT1DBS SOTA)…

Escolho a opção indicada (make active)

Grava-se (ícone da disquete)…

E sai-se do programa…

E volta a abrir-se o Log4om…

Registar QSOs SOTA

Registam-se os QSOs como normalmente.
Todos estes QSOs virão já com a indicação da nossa refª SOTA, com a potência indicada, etc.

Se se tratar de um QSO S2S

Regista-se o QSOs como normalmente.
No caso um S2S com o HB9BIN/p…

Antes de terminar a gravação do QSO, abre-se o separador Country IOTA SOTA (F2) e regista-se a referência do n/ correspondente.

No caso, a referência dele era HB/SZ-027…

Grava-se o QSO como normalmente, clicando em ADD.

Produzir os ficheiros para a base de dados SOTA

Abre-se o separador Utilities e escolhe-se Statistics and awards.

Abre uma janela (abaixo).

Nela escolhemos, sucessivamente os separadores AWARDS e SOTA

Abre a janela embebida SOTA Status.

Em Select award escolhe-se SOTA MIXED.

Clica-se no + (para escolher todos os países)

Em View type escolhe-se Activator

Introduz-se a data de inicio (do que queremos escolher) em Start date.

Clica-se em no  botão View

Aparecem as activações feitas a partir da data indicada (no caso 11-01-2020).

Em Export escolhe-se Current Data.

Aparecem os QSOs registados, referentes às activações indicadas.

Seleccionamos Export as Activator

Escolhe-se a directoria/pasta onde queremos gravar o ficheiro CSV para upload na base de dados SOTA e damos um nome ao ficheiro…

Agora, na base de dados SOTA, faz-se upload do ficheiro, sendo assumidos os QSOs e os cumes SOTA  associados.

Wow… A “software PLL” FOR RX QO-100!

G4ELI, Simon, just presented the world with the latest version of SDR-Radio (Release 3.0.7) which incorporate a very useful feature for those who desire to receive the QO-100.
It a PLL-like but made with software.

The software lock into the upper beacon (NB / BPSK) and compensates the drift of the LNB.
So, all those who have a PLL LNB without GPSDO or TCXO could use this important feature to listen accuratley the QSOs on the QO-100.

In my modest view, this a major breakthrough fore a lot of amateur radio operators!

BIG TKS Simon!

Latest version of SDR-Radio could be downloaded here:

I’m not related with Simon’s work – I don’t even emailed him – but I think that we all should support him by donate some amount.
He deserve it!

Wow! Sotabeams Digital Audio filter

It all started with a 49er kit bought from China (ebay)
Its power output was 550mW. So, I made a few modifications and the power output raised to 2 W.

That was great but RX is a mix of signals.

It needed an improvement but build an effective filter will take a lot of time and effort.


Just after finish the 49er I bought a Foxx-3 (20m) from Kanga UK.

Rx is better but as AF filter will be a added value…

Just about that time, Sotabeams announced a new pcb populated with SMD components without disclose the use.
Shortly after, Sotabeams stated that PCB is, in fact, a digital AF Filter.

Was the this the answer that my TRX kits I needed ?
So, I bought one.

When it arrives I assembled it but until yesterday I hadn’t the time to fully test it.

Fully testing it means to me be on the air with it.

So, yesterday evening I went to 40 m band and no sound on my headphones…
What a hell is happening ?…

Cautious, I check the connections and, after sometime checking and rechecking, I found the guilty piece: A 3.5 mm female audio jack !
I picked another one from the junk box and “hellas” I have dits and dahs on my headphones. 🙂

Testing mean try which I did.

I choosed the Elecraft KX-1. Filter set to 1 Khz (+/-).

First tried to change bandwdith with the switch.
Wow!  I even called Mrs DBS to notice the difference!

I had 3 stations in my headphones but when I narrowed the filter 2 are missing.
And now the small frequency steps aren’t useless…

From Sotabeams site : “The 1,000 Hz bandwidth filter is great for tuning around while the 300 Hz filter allows the user to “home in” on a signal of interest.” – Checked! And wow!!!! 🙂 🙂 🙂

I noticed that I could use the signal led (green on my set)to decode visually once the cw signal was tuned.

The overload led is also very effective. With it is very easy to set the AF input level.

The I tried the gain switch. Not a big deal but it was useful with some sort of signals. Another tool in this little device…

I measured the consumption. It was 31mA@12.5V DC with gain=1 and 35mA with gain=4.
Change of the bandwidth (W to N) just added 1 mA more.
So, considering the possible error in my multimeter, the consumption is within the range publicised by Sotabeams .

Now it goes to proper box.

For sure, it will be used in some SOTA activations, especially in those ones that occur simultaneously with CW contests!

Another good job from Richard G3CWI!
