Bought 2 - easy to build & both worked first time. No instructions supplied, but found a site which was very helpful :- Google "Step-by-Step-Guide-to-Building-the-FM-Radio-Receiver-HEX-3653-Chip-Kit" This is a great step-by step guide, though the author describes the crystal as an antenna! Tip - if using an external antenna, use 2 jumpers (only 1 supplied) linking pins 1-2 & 3-4, or use bits of wire cut off other components instead of header & jumper(s). To use earphone cable as antenna link pins 3-4 only (nearest the headphone socket). Great value for money.

The kit was good and works OK. Best on a separate aerial rather than the earbud cord BUT the sketchy online documentation fails to point out that you need a second jumper on the remaining two pins to ground the earbud common when using this aerial setting. Many other inaccuracies in the various on line posts about this kit.

All of the components were available in one plastic bag. Although there was no cct. diagram in the pack there was plenty of information on the vendors web site. An enjoyable project which gave me a marvellous sense of achievement when I got it working.
