Using a setup for which I had made done some calculations, tonight I was testing the QO-100 (CW / 2.4 GHz on the uplink and 10.4 GHz on the downlink) when a German station (DL3GAK, Udo) called me.
Despite being with the helix antenna (home made) in the hand, outside the window (!!!!), the signal produced is more than enough to make QSOs. My performance as an antenna rotor was poor because I produced a lot of QSB when I’m looking to other stuff…
Next step will be the production of more helix for the OMs of the Quinta do Lambert Amateur Radio Society*… Just after that I will put up all antennas in the rooftop. That will take a litle longer because it will be necessary to attach all equipment in a watertight box.
I would like to thank the many OMs who had shared their knowledge, some of which are Portuguese.
TKS ! CU at QO-100!
* This Amateur Radio Society doesn’t exist but we are 3 OM that live really close by and we like to call ourselves that way…
A ANACOM acaba de me conceder autorização (20FEV2018) para operar no novo satélite geoestacionário do serviço de amador por satélite. O meu pedido foi apenas para o transponder banda estreita (NB), porque não tenho interesse no transponder Wideband (TVA).
Aliás, a potência necessária para chegar ao transponder WB necessita de muita vontade, esforço e investimento do radioamador (100 W numa parábola de 2,4 m, e uma largura de banda de 3,33 MHz, ou seja, 1,33 x 2,5 MSymbols/sec). E a TVA nunca foi do meu gosto!
Assim, partilho o pedido que fiz no site da ANACOM, na área reservada ao serviço de amador (área reservada e com login para cada radioamador).
Comece por entrar na sua área.
É preciso lembrar que o uplink do satélite está fora das bandas atribuídas ao serviço de amador (ver eQNAF).
Então, escolha a opção assinalada.
Agora comecemos a preencher os dados.
Quaisquer que sejam as datas de inicio e fim, devido ao facto de se tratar de uma estação fora das bandas de amador, a ANACOM apenas pode conceder autorização por 1 ano, no máximo, devido à legislação.
Nas condições técnicas adicionais, a emissão será “apontada” para cima.
Para calcular o valor da elevação, sugere-se a utilização do site SATLex, que pode ser encontrado aqui.
Depois escolhe-se o QTH ou indica-se outra localização (no meu caso escolhi a estação fixa principal).
All radio amateurs are invited to participate in Portugal’s National SOTA Day, tomorrow April 1st, an event that is meant to both highlight and encourage participation on the Summits on The Air program.
The “party-on-the-air” is also meant to celebrate SOTA – Portugal´s sixth year in activity, started precisely on this day, in 2011.
Long time and current participants, as well as amateur radio clubs, are particularly encouraged to invite other amateur operator´s to tag along their planned activities in order to increase the program’s awareness.
Certificates (electronically sent) will be available to activators, chasers and SWL registered on SOTA´s Database and after the upload of their day´s logs.
No other rules apply other than the Summits on The Air own set of procedures.
This is not a contest, just another way of enjoying and celebrating SOTA´s unique pleasure of amateur radio activity.
All queries regarding Portugal´s National SOTA Day 2017 should be sent to his email (lookup QRZ.COM) or diasotaCT@gmail.com
The following station annouced their intentioon to activate one summit tomorrow, April 1st, to celebrate the CT National SOTA DAY (no special order)

After long time without any Sota activation due to a respiratory infection, the weather forecast indicates that Sunday will be a sunny day. 🙂
It will be a cold but sunny day!
So, I decided to give a try to my lungs!
Early in the morning I went to Serra da Freita Power station and parked the car.
It was a perfect day for this time of the year, with a cold and strong wind. But who cares ?
My first bad decision was to take advantage of a tree instead of erecting the fishing pole.
A rock helped to launch the string over the tree. Then the rope get tangled in a branch.
The half burned pine tree shown no cooperation… Fires in the summer are enough. A SOTA activator seems to be too much!
But one should never give up, right ?!
Second launch and the rope was not in the correct position. So, I pulled a little.
Bingo! The rock turn around a branch and now is firmly tie to the stubborn pine tree!
Pulled from several directions and nothing!
So, the fishing pole was used to untie the rope and the rock .
Problem solved just after 40 min… 😦
Another small pine tree are waiting to hang the end of the rope…
Easy one. The rock will be used as weight.
My thought at that time was”…unwrap the wire, erect the fishing pole and it’s done. I will be on air.”
But things are never that easy…The small twigs left by the burn bushes made the task very difficult. The wire get rolled up and… It seems to be an easy task!…
At this point I start laughing ! It took me over 1 hour just to have the wire in the air!
Everything set, let’s CQ CQ on 60m…
What could go wrong ?!
I notice something strange in the SWR of the KX-2. At beginning the tune is perfect and SWR=1:1. Shortly after the SWR increased!
I stop. Checked SWR with ATU: “All systems go”…
Starting CQ again. CQ CQ CQ SOTA DE [SWR going up]. Stop.
Less power. Same problem…
Let’s give a try in another band. Same behavior!
Forcing CQ, I get one spot on 14 MHz (6 dB SNR in G-land)…
ZERO answers, no QSOs!
One must to understand when it’s a “no day”! 🙂
So let’s enjoy the mountain and forget SOTA, i e, phase 2 of Sunday.
On 1st April 2017 we celebrate six years of SOTA program in Portugal.
So, we invite all amateur radio operators to take part in those celebrations named National SOTA Day 2017, which will take place on April 1, 2017 (Saturday).
The essence of the celebrations is to have multiple summit activations all over the country on this day.
Last year almost 50 activators in 21 SOTA summits produced 750+ QSOs (7 MHz to 1.3 GHz).
Despite the bad wx and propagation conditions Portuguese callsigns (CT/CS/CR/CU) in SOTA ref were in Portugal mainland , Azores and France.
The activity aims to promote the SOTA program and allow sensitize the amateur radio community for this kind of healthy and funny activity.
Although there are certificates to the participants (activators and chasers), the National SOAT Day – 2017, as well as the SOTA program, it’s not a contest.
It will be a “SOTA on-the-air party” and therefore all amateur radio operators are invited.
All Portuguese clubs were invited to join the activity.
All amateur radio operators who are Activators are specially invited and encouraged to bring other hams or prospective hams for activation, enabling others to experience a SOTA activation.
It is suggested that the activations should take place:
• From 09.00 and 18.30 (local time) on April 1, 2017;
• Using their own call sign (/ p);
• Using the simplest possible equipment (QRP in most cases, including portable radios V / UHF);
• In SOTA summits with the highest possible score:
• In the amateur’s radio operator area;
• In any CT/CU/CT3 summit.
The KISS concept (simplicity, simplicity, simplicity …) will be used throughout the activity: The only rule is to comply with SOTA rules and having fun!
As explained before, there will be certificates to the participants who activate a summit (by SOTA rules) or have a QSO with one activator/summit on that day (chasers or SWL). Other than that, they should send photos or videos of their SOTA activity to CTsotaday@gmail.com
This will be a great opportunity to chasers abroad Portugal.
Please feel free to ask any questions to the email.
In behalf of National SOTA day organization,
