For 24GHz a smaller horn fits inside the 10GHz Horn. It is fed by circular waveguide from the rear of the dish in much the same way as the 10GHz system. The "Wave-guide" is made from a standard (Engineering not plumbing) pipe with an internal diameter of about 10.7mm. The Horn, Waveguide and circular to rectangular transition were made by Ian G8CPJ.
This recording is of echoes from G4NNS. It has been made by sending brief elements of the callsign and editing together the resulting echoes. The elements were sent as G 4 NN S.
Listen to W5LUA in QSO with G4NNS on 24th June 2006 24GHz
The QSO has been edited so that you hear both callsigns, the Report RM, RR and 73.
The transverter is placed behind the dish with dual mode circular waveguide feeding the horn at the front. The Blue object it the TWT producing about 25W at 24GHz.
