YUP, that's the common misconception caused by the misuse of terms. I read that exact quote earlier today. TRUE GROUNDWAVE propagation requires vertical antennas relatively close to the ground and basically peters out drastically above 3 MHz. Ever notice how a broadcast station on 550 KHz can be heard much further away than a similar powered one on 1600? That is the difference in groundwave versus frequency. I don't expect you to believe or even agree. You have never been wrong before so why would you start now.
