Description
This is the BLANK PCB for the Portsdown DATV system multi-band switched local oscillator filter 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.
It is highly recommended that you use one in the Portsdown transmitter – see https://wiki.batc.org.uk/LO_filters for more details and the parts list and schematics.
