Description
This is the BLANK PCB for the Portsdown DATV system 2 way RF switch. It decodes a signal sent on the symbol rate switching lines (all 3 high, which was previously unused) which is used to switch between the LimeSDR output, rather than the Filter-modulator board.
It is NOT the assembled unit as shown in the picture but just the BLANK PCB to enable home construction but please note it uses fine pitched SMD components.
See https://wiki.batc.org.uk/2-Way_RF_Switch for more details and the parts list and schematic.
