The closest ham transmitter that might be useful for MW is a 160 meter rig, modified to operate at the lower frequencies of the MW broadcast band.
I had a ham rig a couple decades ago, a Yaesu tube final unit which covered the old ham band that is now the “X” extended AM band and tuned down to 1.630Mhz. Was neat to fire that unit up into the CC coupler on 1670…but the audio was for doo doo because it was very narrow band for voice..about 3khz and lower.
Anyway, you will need to do some serious modification to a ham 160 meter rig, both for frequency of operation plus filtering, AND open up the tin can bandwidth of audio it will have so you can have decent audio quality on the MW frequencies.
Over at my forum I posted information and schematic to a perfect linear amp to drive a CC coupler..ie your T-8 coupler. And that linear amp can be driven by the TH transmitter, or any other Part 15 compliant transmitter such as the AMT 5K. And trust me, it will be a heck of a lot easier to build that amp than it would be to modify a 160 meter ham rig for use in the X MW band.
