The rebuild<\/h2>\n\n\n\n

Construction has commenced and currently the transmit upconverter is being tested. The F6BVA 3cm transverter that was going to be used seems to be not suitable because the bandpass filters incorporated into the PCB appear to be much narrower than anticipated and centred on the narrowband segment around 10.368GHz. An alternative using a Mini Circuits connectorized mixer and Mini Kits multipliers is being developed. <\/p>\n\n\n\n

Parts have been sourced from many individuals keen to see GB3XY back on the air. Here is a list of what has been procured so far:<\/p>\n\n\n\n
