Lee’s report coupled with Daniel’s might provide some hope for legal FM communitycasting. It seems, through experimenting, that a means to extend the range of a certified FM transmitter is elevation. Lee’s data would indicate that his FM system range is approaching what is reasonable to expect from AM.
As researchers say as they close their published reports, “Though this research suggests blah, blah, blah, more experimentation is needed”. More is needed but so far it looks good.
BTW Lee, I haven’t checked for a while but the Linx stuff was available from Digikey. Linx is rather restrictive in their sales policies so go elsewhere for their products. They are well engineered and well fabricated and I recommend them to hobbyists looking to experiment with part 15 devices outside the broadcast bands.
