IW3FZQ
microwave

I am very active in microwave world and not in contest and test only but equipment construction also! Except for the transceiver that I use to drive several transverters (IC202, IC402, FT290), all the rest are homemade gears: transverter, pre-amplifier, amplifier, guide-filter, horn, illuminators, etcetera. For the modules calibration I use homemade frequency-meter, homemade signal generator, a Marconi up to 18 GHz power meter and a Hewlett-Packard spectrum analyzer. After few years of work, I have achieved transverters for 1,2 - 2,3 - 5,7 - 10 - 24 - 47 GHz (3,4 GHz unauthorized in Italy). At the moment I have not idea to build 75 GHz transverter because I will be the only to have it and I can not to do qso with......myself !!! In the 150 KM range, there are many stations active in 6 millimeter band (47 GHz): IW2BNA, IZ2DJP, I4QIG, I3CLZ, I3ZVN, IK3NWV, IW3EHQ, I3SOY, S51JN but no one of them is QRV in 75 GHz band. Under, you can see some pictures of homemade transverters and relating particular, besides, the performance during some contests, including the 24 GHz/250 KM bilateral SSB QSO with S51JN/P and 47 GHz/188 KM bilateral SSB QSO with I4QIG/4.
