Hi,

1. set switching frequency to LF or MF band
2. remove output filter
3. add LF or MF Lowpassfilter
4. input NF
5. have high efficiency AM-Transmitter?

stupid idea?

These class d audio-amps are getting cheaper and cheaper...
Using one of this modules as a power supply for an LF/MF class d rf-amp  could be an interesting idea:

At the bottom there is a chat and some people asked about PCBs
The answer is: If you want to build one up for yourself, pcbs are available.
