I use a different idea on LF from 2013    IRAUDAMP7S-150 - abt 200-220W RMS Output on 136 (one ch) at very long beacon's time with abt 90% total efficiency (~220V 50Hz -> 136kHz) now - I use Chinese full analogue ($38 2013) of  IRAUDAMP7S
The theory of Class D Audio (linear) PA
I do not know how to achieve the very high stability to your ideas

2KW PA from the same Chinese manufacturer IRAUDAMP9 on ebay  $179

2016-04-29 22:56 GMT+03:00 Eike DL3IKE <[email protected]>:

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?
