I recently attempted, and failed, to buy a sstran amt 5000 for $229. after two months of waiting I opened a claim with paypal to get my money back. After I received my refund I impulsively bought a Procaster AM transmitter for $696 with $55 for shipping for a grand total of $750 plus about $100 worth of pawn shop studio equipment as well as wires, ground rods, and a long aluminum pole to mount it on. The tx has amazing range of about two miles when well tuned and grounded and is connected to a audio and power source inside the house via a cable that i believe is nothing more than a length of phone cord. This allows for the tx to be almost entirely controlled from inside the house with the exception of the tuning and frequency selection. The only problem i have withe the tx is that there is no good way to ground it without breaking part 15 law. The instructions call for an eight foot grounding rod, however this combined with any length of wire would violate part 15 law leading me to believe that when the fcc was inspecting the tx for certification, it wasn't grounded at all. Bearing that in mind i, knowing i had to ground it for lightning protection, bought forteen feet of six gage wire and an eight foot copper ground rod and plan to add even more grounding in the future.
All in all I'm very pleased with the tx. Even with my minimalist approach to the part 15 hobby i can still cover my neighborhood as well as several others in the area. I haven't had any problem from ether the fcc or the tx and i don't think i will. if you're looking for a good part 15 tx the Procaster is what i recommend.
