I have the Opendous-designed NooElec H.F. up-converter. Conventionally, when this converter
is enclosed in the specified aluminum shield box, the power to the converter is to be supplied via a usb
I preferred the converter independently powered from batteries, and with those batteries also enclosed
in the shield box. I went ahead and tried it, and it has worked out well. Here's the write-up with pictures:

I also show an experiment with the converter which involves only analog electronics, no SDR etc. involved.
