|RF Coil Former Pack|
Coil former, ferrite slug and shield can. Can be used for SiDRADIO (one set) or the Vintage TV A/V Modulator (two sets required).
We supply the SBK-71K. The Jaycar LF1227 set originally specified for SiDRADIO is no longer available. There are a few differences so some slight modifications need to be made in order to fit the new coil former on the PCB:
1) The SBK-71K has five pins rather than two. The extra pins can be cut off or, where they will fit into an existing PCB mounting hole, used as tap connection points.
2) The SBK-71K is slightly smaller so you will need to use 0.25mm diameter ECW rather than the 0.3mm diameter specified in the SiDRADIO parts list. The number of turns remains the same.
3) You may need to bend the pins slightly to fit them into the PCB mounting pads.
