Morse Day! 27th April

The best way to celebrate Morse Day was to do some CW QSOs.

A friend asked to be helped to make his the first CW QSO.
He was successful and very very happy at the end of the QSO.

It seems that this is a true image of what was going on during the QSO…

My first CW QSO using QO-100

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…

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!

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!
