Don ND6T has been helping us come up with a good simple low pass filter for the MMM (Steve Smith and the FCC insist). At the end of one of his e-mails, he shared this QRP Colorburst gem:
Be prepared to be occasionally amazed. Back in the late 70's I worked all over the western U.S. with under 1/2 watt. Regularly. Even a QSO with a UA0 (Siberia) with under 1 milliwatt, he having answered my CQ! I was seeing if I could "get out" using a single "D" cell flashlight battery that was too weak for the flashlight. All using a colorburst crystal. Oh, and a dipole 100' high stretched over a creek.
