| Our
10GHz
rover stations A
nice part of microwave activity is to go outdoor and make the
contacts (as long as it is nice weather). This is really
portable activity, needing some optimization and ideas to get
all things working flawlessly. We are beginners, but we didn't
want to reinvent the wheel, thus we took some inspiration on
the Web from more experienced microwavers. Hopefully, we
did some improvements...

| The
MicroWave
contacts
we made While
being very far to set new records, we had great fun with
every single contact we tried. Even at the first test from a
corner of a room to the opposite one, we felt the challenges
of being a microwave operator. In
this page we keep a Logbook of the 10GHz contacts we have been
able to establish with our equipments, together with a photo
gallery and some comments.

The
3cm
SSB transverter
we built
Also listed in Our Projects page, we describe here
one of the two 10GHz SSB transverters we built around pieces
of LNBs for satTV. There are faster and easier
ways such as commercial kits, but the fun/$ ratio is much
lower. And we learned a lot too... |

A 1W
Power Amplifier
upgrade for the 10GHz transverter
We briefly describe here the 2-stages PA built to increase
the power of the transverter without impacting its originally
compact design.

| GPS-based
universal clock generator
As expected when we
presented this project some time ago, a perfect application
is in microwave ham stations. Frequency accuracy is a key factor
for a successful long range SSB microwave contact, together with
stable antenna mount, accurate beaming and good propagating
conditions: only the last factor should be the one out of your control.

| An
experimental 10GHz
beacon Soon
we learned how much important is to have a reference signal in the
3cm band to make on-the-air tests of equipments and antennas.
To help ourselves and the hams in our area that will (sooner
or later) start-up their activity on this band we have built a
3cm CW beacon, identified as
IW9ARO/B. While we write this page, you can check its location
and status at the site www.beaconspot.eu

WORK IN PROGRESS

Antennas,
feeds and cables
Few mW at microwave
frequencies can do miracles if you have a good antenna setup,
and at 10GHz gains in the range of 30~35dB are very manageable
for amateurs. Home building microwaves antennas can be easy and difficult at the same time:
small sizes allows simple
structures and light materials, while mechanical tolerances become very
tight. We just started working in this field, and
we like to present our early results.
