Hello,

Anybody know of an integrated I/Q modulator that can work with LO down to 500KHz? It seems all are tailored for LO at 50MHz or more.

I need it to do some vintage experiments with AM C-QUAM stereo modulation.

Any suggestion?

Thanks

Let's hope to see soon some new photos
 
Liebe Freunde und Wegbegleiter,
heute vor 15 Jahren wurde das Wunderland eröffnet. Wir haben heute also quasi Geburtstag und wollen das als Anlass nehmen  Danke zu sagen und ein bisschen zurückzublicken – gefeiert wird dann nach der Italieneröffnung. 
Hinter uns liegen fünfzehn fast märchenhafte Jahre. Hätte uns jemand im Gründungsjahr erzählt, dass wir jährlich um die 1.3 Mio Besucher aus aller Welt haben und zu einer der bekanntesten Sehenswürdigkeiten in Deutschland gehören werden, hätten wir ihn wahrscheinlich für verrückt erklärt. Gerade in der Zeit vor der Eröffnung wurden wir häufig als Spinner bezeichnet und kaum jemand glaubte, dass man mit Modellbahnen Erfolg haben könnte.
Um ehrlich zu sein – auch wir hatten bei allem Optimismus am Anfang große Ängste. Am ersten Tag hatten wir auf eine lange Schlange am Eingang gehofft, es kamen aber nur ein paar hundert Gäste. Am darauf folgenden Wochenende dann die Erlösung mit einer Schlange bis weit vor die Tür und der Start eines Märchens, welches uns erlaubt jeden Tag  an kreativen Spinnereien zu werkeln. 
Und genau dafür wollen wir uns bedanken. Mittlerweile waren fast 15 Mio. Besucher im Wunderland und dieser Zuspruch ermöglicht es uns so verspielt zu sein. Wir haben 350 Wunderländer, die mit viele Liebe und Hingabe kleine Dinge erschaffen. Wir können uns erlauben zu spielen und nicht nach Zahlen und mit strengen Vorgaben zu arbeiten. Es geht nicht darum in einer gewissen Anzahl Stunden etwas zu erschaffen, sondern gute Geschichten zu erzählen. Diese Freiheit ist sicher nicht immer effizient, aber der Raum für kreative und liebevolle Details und Ideen. Unserer Meinung nach lässt sich Liebe nicht in Zahlen ausdrücken. Uns ist bewusst, dass wir so nicht arbeiten könnten, wenn nicht so viele von Euch Jahr für Jahr zu uns kommen würden. Dafür ein ganz großes DANKE und ein kleines Versprechen.
Mit 15 naht die Volljährigkeit und die Pubertät verleitet dazu kindliches abzuwerfen. Wir werden uns dagegen stellen und alles dafür tun, dass das Spielen, Tüfteln und Erschaffen immer an erster Stelle stehen wird.
Wir sind unendlich dankbar für jeden der letzten 5479 Tage und hoffen auf viele weitere.
Danke für die großartige Unterstützung!
Eure Wunderländer

Dear friends and companions,
today 15 years ago we opened the doors to Wunderland. It is our birthday, so to speak, and we want to take this as an opportunity to say thank you look back a little bit – the celebration will have to wait until after the opening of our Italy section.
We are looking back on fifteen, almost fairytale-like, years. If somebody would have told us back when we opened Wunderland for the first time, that we would receive around 1.3 million visitors a year from all over the world and would one day belong to the most popular attractions in Germany, we would have surely thought they were crazy. Especially in the last few months before the opening we were constantly called nutcases and almost nobody believed that model trains could lead to success.
To be honest, despite all our optimism in the beginning, we were still scared as hell. On the first day we hoped for a long queue at the entrance, but only a few hundred guests actually came. Only on the following weekend salvation came with a queue leading far outside our doors. This was the beginning of a fairytale, which enables us to tinker with creative ideas every day.
And this is what we want to say thank you for. Since then we received almost 15 million visitors in Wunderland and this strong support is the reason we can focus on all our small playful details. Over 350 “Wunderlanders” are creating small things with lots of love and devotion. We can afford to play around without looking to closely at the figures and without following strict rules. For us, it is not about creating something in a set amount of time, but to tell great stories. This freedom surely is not always very efficient, but leaves us room for creative and loving details and ideas. We believe that love cannot be expressed with numbers. And we are well aware of the fact that we couldn’t work like this, if not this many of you would come and visit us year by year. For this, THANK YOU and a small promise: When you reach the age of 15 you get closer to becoming of age and puberty makes you want to dismiss everything childish. We will stand against this and will ensure that playing around, tinkering and creating will always be our number one priority.
We are unbelievably thankful for the last 5479 days and are hoping for many more to come.
Thank you for your wonderful support!
Your Wunderland Team

From +Quartz -- interesting analysis -- heard something similar from someone who lived through transition to Euro in Spain and noted its effects on people's jobs/economy

Brexit might be the wake-up call Europe needs to prevent the EU from wrecking the whole global economy.

Introduction

Ciao a tutti, mi chiamo Paolo, alias Samvise. Un soprannome un pò curioso, non vi pare? Tutto é iniziato anni fa, quando intrapresi per la prima volta la strada telematica... feci parte di un Net amatoriale inspirato al romanzo "Il Signore degli Anelli" di Tolkien, RingNet appunto, ed é proprio lì che assunsi questo alias.

Classe 76, ho sempre vissuto in Italia, se escludiamo alcune brevi parentesi lavorative e turistiche. Di formazione tecnica, ho iniziato a usare i computer già da 9 anni, scrivendo piccoli programmi in Basic su un tascabile Sanco TPC-8300, per poi passare a un Apple //c e quindi ad un PC.

Inizialmente programmavo solo in Basic, poi ho provato il Logo (a scuola, che ricordi!), il Pascal, l'assembler, il Visual Basic, per arrivare infine al puro e semplice C. Non visual nonsochediavolocosa, ma il puro e semplice C che, con la scoperta di Unix, ho proficuamente integrato con quelli che sono gli standard posix, iniziando così a parlare anche di fork e non solo di printf ;)

Conosco anche il php, il python e la gestione di database (in particolare mysql e postgresql ).

Ho studiato dapprima elettrotecnica, per poi cambiare "in corsa" e finire in elettronica.

Dal punto di vista lavorativo ho fatto un pò di  tutto, dall'operaio all'operatore di call-center, dal tecnico manutentore al  sistemista informatico, dal progettista elettronico per finire oggi nel mondo dell’aviazione.

I miei interessi  sono molteplici, e spesso focalizzati sull'aspetto tecnico delle cose, ma non solo.  Gli hobby di tutti i giorni sono fai-da-te, fotografia, modellismo (in particolare ferroviario, ADORO i treni), ma quando c'è  l'occasione mi piace anche viaggiare, camminare in montagna, andare al cinema, al  ristorante o andare a un concerto.  Ho provato vari sport, e l'unico che mi riesce decentemente é lo sci, anche se ultimamente non lo pratico più di tanto.

Mi piace molto anche la musica. Ascolto un pò di tutto, dalla lirica al metal, con pop e rock i generi più ascoltati. I Toto sono il mio gruppo preferito, ed un tempo suonavo con i GGM, il migliore gruppo di amici ch'io abbia mai avuto. Sono anche appassionato di computer graphic e mi diletto a fare piccoli fotomontaggi, anche se non disdegno il disegno tecnico con il CAD.

Sono stato negli scout Agesci per quasi 6 anni ed ho imparato ad apprezzare il "fai da te" e la vita libera. Apprezzo la forchetta e si, un bagaglio di troppo c’è, ma fortunatamente non é troppo esagerato.

Sono donatore di sangue presso l'AVIS Milano e per anni sono stato volontario presso la Croce Bianca Milano, associazione di volontariato e pubblica assistenza.

Hello everybody, I’m Paolo, alias Samvise. A funny nickname, don’t you think so? Everything has begun several years ago, when for the first time I used a bbs… I was member of an amateurial network inspired at the fantasy romance “The Lord of The Rings” from JRR Tolkien, RingNet, and it was there that I first took this nick.

Born in the ’76, I always lived in Italy, except few digressions for work and tourism. Of a technical background, I started using computers already at 9 years old, writing little Basic programs on a pocket Sanco TPC-8300, to switch later on to an Apple //c and ultimately to a PC.

Initially I coded only in Basic, then I tried Logo (at school, what memories!), then Pascal, Assembler, Visual Basic, to eventually land at the pure and simple C. Not visual IdontKnowWhat, but simple C which, with the discovery of Unix, I successfully integrated with some posix standards, thus starting to write fork and not just printf ;)

I know also php, python and database management (in detail MySQL and PostgreSQL).

I first studied electrotechnics, to change “on the way” and end up with an electronic degree.

From a working perspective I did a bit of everything, from factory worker to call center operator, from engineer technician to network administrator, from electronic R&D to end up today in the aviation world.

My interests are many, and often focalized on the technical aspect of things, but not only. My everyday hobbies are DIY, photography, scale models (expecially model railways, I LOVE trains), but if there’s the right occasion I also like travelling, hiking the mountains, watch a movie, and going at the restaurant or attend a concert. I tried many sports and the only one that I can manage decently is skiing, although lately I don’t do it too often.

I like music a lot. I listen everything, from opera to metal, with pop and rock among the most favourite genders. Toto are my favourite band, and time ago I used to play with GGM, the best friends' group that I ever had. I also enjoy computer graphic and now and then I like making little photomontages, although now and then I also like doing technical drawings with CAD.

I have been in the boy scouts for about 6 years and I learned to appreciate the DIY and the free life. I enjoy eating and yes, I have some extra baggage, but luckily it’s not too exaggerated.

I am a blood donor and for years I have been volunteer in the Ambulance EMS (Something similar to paramedic, although with less qualifications).

Hallo, ich bin Paolo. Obwohl ich ein bisschen Deutsch sprechen, meine Fähigkeiten in diesem wunderbaren Sprache wirklich niedrig ist.

Also bitte, wenn Sie können, schreib mir bitte in Englisch, danke.

你好我係Paolo(保羅). 我的老婆教我講小廣東話.

因為我的廣東話係唔好,寫我英文,唔該.
