Hi Peter,

Sorry, what I meant was to use only one Grove MOSFET board, to supply 12V to the QDX when it's on.

When that one MOSFET board is off, the QDX is powered by the string of diodes.
Yes, that would certainly work, but I needed to be able to turn off the power completely by remote control (this was so that I could switch to using an SDR receiver instead of the QDX over the USB extender).? Hence I needed 2 MOSFET switches and they could be in parallel or series, it doesn't make much difference.? Incidentally, the Grove MOSFET boards are pretty cheap - only ?3.80 each here i.e. a handful of dollars, so they didn't break the bank!
