Dave, G0IVA and Martin, G7MRF, set up their equipment at David's house during late February 1999. Here are Martin's own words, received in a recent email to the webmaster....
Here’s a brief resume of our initial 47GHz tests that we have carried out at the QTH of David, G0IVA
Over the winter, David built his transverter based on the DB6NT design
using the DB6NT local oscillator and a 2m IF. I have built two of
the DB6NT transverters but using 1296 as the IF and the usual DDK004 and
WDG009 as my local oscillator. David is using a 35cm offset dish with
his own design dish feed and myself a 10" dish with a cassegrain feed.
After initial alignments in the shack, we moved outside to set up both systems together at the bottom of the garden, looking back at the signal source that David has modified. After netting my DDK local oscillator onto David's (to help with later trials) we were both taking 59 signals from the test source and, with the diode on the output of the test source removed, using just a harmonic, signals were 51 on both systems.
After more playing we both concluded that it had been a successful initial shakedown and started to plan our first outing (gradually increasing the distance if all goes well). We hope to be active in the April 24/47GHz contest as well as the RSGB 432 up contest in early May.
It is our intention to write up our construction of the 47G systems for inclusion in the RSGB Microwave Newsletter. This will be a more detailed piece than these notes
