Hi,
Since yesterday we see only 30 watt of output power in the telemetry of the beacon. Both Walter and myself are on holiday returning July 15th. So the 1296 moon beacon will not be active in the coming week.
We will report when the spare or main PA is back on line.

Today the PA got re-installed again at the 1296 moon beacon. We got several suggestions on the mods, following modifications have been done to the W6PQL PA . The output board has been glued to the copper spreader using Silver Epoxy ( CW2400 ) Soldering the components back to a new board has been done using Pb , Sn , Ag solder ( 2% silver ) A new MRF13750H has been soldered to the heat spreader 4 output capacitors in parallel are on the output mounted vertically VDD is now at 40 VDC output power is around 400 watt. We cross our fingers and hopefully these modifications will hold.
