Hi,
I am thinking of building a simple FM receiver following the circuit on this website **broken link removed**
I have most of the components available, except for L2 (22uH RF Choke). Can I wind it myself in the same way as winding an inductor? i have built various FM transmitters and usually hand-winding works well.
If I cannot do it myself, can I use the resistor-like inductors instead? There are so many for cheap prices on ebay. Btw, is the value critical?
Alternatively I have a few old broken radios, can I possibly salvage it from the existing circuit?
Any advice is appreciated. Thanks.
