Hi Kelly,
In France , young Students create FM radio area without authorization for fun on weekends . Kits are also commercially available but the frequency is not stabilized by a PLL. The idea is to make a diy issuer of good quality for a small budget so they do not disrupt étidiants receipt of the official radio stations.
I capapble to design such a project alone but if others wanted to participate in the forumers tor elaboration minimum feature I opened the topic.
Thanks for your help.
François
