Looks great, some useful info on there too.
A couple of side notes. You seem to be using a old out of date and insecure version of SMF RC3. I'd be worried about that. The version of TP is also behind.
The article about, the BelkinFMTransmitterModification, doesn't seem to describe the problem, and what it was set out to achieve. I'm assuming it's showing you how to upgrade the antenna? I know the range isn't too good on these things.
Apart from that, nice job.
