The 2.4 GHz transverter has been completed and I used it in the vhf/uhf field day on the weekend of 15/16 November.

Construction began on Sunday 9 November with the first components soldered onto the sequencer board, finishing on Friday 14th November when I finally measured the transmitter output power.

The next day I was on Mt Ginini, with a 24 db gridpack dish (obtained from The RF Shop) attached to the transverter, receiving a big signal from Ted VK1BL at Mt Coree.  I replied to his call and asked how he was hearing me.  He replied immediately! This was my first contact on 2.4 GHz, made all the sweeter by the knowledge that the transverter was home made.

Together with some other “firsts” on this field day, it made for a very good weekend.

I have written up the details of the design and construction and submitted it as an article for AR magazine.  The article was published in July 2009 and can be found in the AR archives here.
