Hello.

Actually I am anything but a mud duck.
I run the minimum power needed, sometimes less than 100 milliwatts.
I make an effort to do a clean RF signal, frequently on AM I will limit myself to 90% modulation, both from a clarity standpoint as well as spectral conservation.
I use telephone type drop in modules with audio filtering or perhaps carbon elements in this effort.
I keep transmissions short and to the point, hello, the point, good bye.
