Nothing new

Nothing has really happen since last weekend.
Worked some on the moon during the weekend but very low activity so mainly some tests with Bernie ZS4TX using different polarization.

Have continued with the Italab pallet amp I purchased a while ago but the progress is slow.
Did CAD and milled a PCB for the ON7EQ Arduino controller and put in screened box with feed through caps and inductors on the board that will hopefully work as RF sheild to avoid problems with RF on the input pins to the controller.











Will reprogram it later to also include the designer ON7EQ in the startup sequence.
I just did an initial test and tried to familiarize myself with the code.
The startup sequence fault handling seems to jump the 50V supply voltage because it never stops there as it stops on every other voltage or current measurement so I need to test some more another evening.

Have received the boxes for the preamp and balun but need to CAD and print a support for the balun before I can put everything inside and attach it to the antenna.
Hopefully the weather will be good in the weekend as now its very damp and wet so everything is soaked.
