Very nice looking units.

I have the Kuhne boxes to make up a 10GHz to 432MHz transverter which I need to put together again, and I was given an old narrowband transverter for 24GHz that a friend realigned for the part of the band that is now in use. The other problem is that it uses a switch to swap from transmit to receive, so needs a bit of manual intervention...

I'll take some photos and post them up when I get a moment.

Hi Iain many thanks for the write up, it always amazes me how people manage to build kit for those high frequencies as the thing likes inductors and capacitors must be very challenging to fabricate.

Interesting and I have to admit I've plenty to learn on this subject, great thread starter thanks.

Since there's not much in this section yet I thought I'd kick it off with some pictures of a recently completed project, namely transverters for 24GHz, 47GHz, 76GHz and 122GHz. Each transverter is in the same sized diecast box which fit a common dish antenna.

As well as the 4 transverters, the cases hold the FT-817 I.F. radio, a 10MHz OCXO reference, 3 LiPo batteries (3 cell) and a boost converter to maintain 12.5v output from the batteries (which are nominally 11.1v). The necessary power and coaxial cables are also kept in the cases.

The transverters sit in the lower cradle. Each has a waveguide feed that illuminates a sub-reflector fixed in the dish.

The FT-817 sits on top and the 10MHz reference is attached to the side with velcro.
