Hello all.

I am looking for interested hamradio ops in 1.2 GHz testing from any #.

My system includes an IC-910 with 1.2 GHz module (10W TX), heliax coaxial and 33 el. tonna yagi. May operate from KM17tw (that's where is my QTH) or portable.

Hello sir,
Nice system you've got there!
Personally I have not got a 1.2GHz system but a 10GHz system, but another member may be interested to make a QSO with you.

I am looking for 10GHz QSOs in Greece and Europe but I am missing a final part in the chain, a WR90 flexible waveguide 20-50cm.
If anyone has that part for sale please let me know.

Thank you vy much for your kind reply!

I iish I had the time to make/buy a transverter for the 10 GHz band that really seems really interesting (like all the rest of the microwave bands). I hope that in time I will obtain one and will try.

There is some recent information about licencing on use of this band from SV land here(Greek language):

62.103.213.195/10Ghz.htm

The use of the band in Greece for the hamradio ops is on a secondary basis, unfortunately.

Thanks for the usefull info, really interesting for the Greek members!

You cannot buy many equipment on 10GHz. Usually the equipment is homebrown in 10GHz and up.

I have sent my transverter project at Dubus for publication. It will be published on 3rd or 4th issue of 2009. After the publication at the magazine I will make it available in the Greek Microwave Group site in the projects section.

It is a transverter than anyone can build, like a puzzle. You do not need expensive PCBs and materials to build it, I think it is really interesting.

I have sent also an email to the person in charge, maybe they will let us put the relevand form in the GMG website, in order to be available for the Greek members to download it.

It will be also great to put a link of your website here, in the GMG site, as it is very interesing website. Just click on the "Submit WebLink" menu after you login to the site.
Put a link of the GMG to your site too if you like, we will appreciate this.

UFB!Thank u vy much fer info!
I will be looking fw to seeing the design.
I had in mind the DB6NT transverter www.ssbusa.com/mkutv2.html but homebrewing is fun and wallet saver :)

you can see a picture of mine here neazoi.com/lab/dsc01149.jpg
but this is ages ago, it has been much inproved sinse then.

Yes the one that you show is a classic transverter, all in one.
I have seen it in many constructions but I prefer making one on my own the way I want it :)

Note: Transverters are lossy and bad compared to direct conversion equipment.
There are ways to make direct ssb modulators/demodulators for 10GHz, that are far better than transverters. See www.microwave.gr/index.php?option=com_content&task=view&id=80&Itemid=104 for more info. They are more complex though...

TU fer info!

I am also looking for the 55 elements version (one day!) 2x stacked scenario at 19.9wl each....
