OMG What am I going to do with this??

I was not aware that transmitters needed FCC approval to be used on ham bands. Sold specifically for ham band use, commerically, yes.

They just need to meet the requisite power and bandwidth rules.

As far as AM goes, I hear AM all the time on 80 and 40 meters,
and even on 160 meters at times.

A broadcast band transmitter of say 1 or 2 kW or less, if not specifically designed for only the lower parts of the band, should be easy to get to work around 1.9 MHz. It would be crystal controlled, of course, but any competant builder could build a tube or transistor buffer amp to take output from a synthesizer or VFO and use it to feed the nominal crystal oscillator.

If the transmitter did not have a built-in audio limiter with essential bandwidth filter, a simple external filter would satisfy the bandwidth requirment. If it did have that, the internal audio filter would need serious modification.

Somebody should take this transmitter and do it!
