Hi Noel,
That's a Grundig MicroSat STR-100 receiver for analog ATV
It has Low Threshold settings, and runs from 12V!
The CAT5 port is used for the infrared remote "eye"
I use that RX also to provide the LNB voltage (19Volt out of the 12V supply)
That way I do not need a step-up converter when running 12V portable!
All very much work in progress
EDIT: finished drilling the lid! All 128 holes...
ventilation is everything!
