for a kit i recommend the SSTRAN AMT5000 weighing in at about $295.00 followed by the AMT3000 for $95 for certified the first choice would be procaster $695 followed by a talking house Version 5 $95 for FM the Decade MS100 all the way at $500
i personally avoid hamilton (customer service issues) and the iAM Radio transmitter (search the forum archives for the explanation of why not) avoid the TH external atu unless you can acquire it for $50 or less. it’s not worth much more than that imho. certainly not worth $295.00 plus the large shipping.
the TH ver5, and both SSTRANS will do 540 khz. the procaster cuts off at 1200 khz
